To Jeff Fritz,

First, I want to thank you for the many great reviews you have been providing enthusiasts (including myself!) for years.

If I could ask you for a small request with a simple, honest question. Would Jeff Fritz trade in a Simaudio 700i integrated amplifier for a T+A Elektroakustik PA 3100 HV integrated amplifier? Hoping that the PA 3100 HV is better in all aspects. Much Appreciated.

Thank You,
Pat Del Sordo

What would Jeff Fritz do? Hmm, that’s a bit different than what would I advise you to do. But here goes: I would not make the trade, and here’s why. First, the Moon Evolution 700i retailed for $13,000, and has now been superseded by the v2 version. That means its trade-in value is not as great as it might be if it were a current product. The PA 3100 HV retails for $23,500. That means your out of pocket for the “upgrade” is likely to be well into five figures. If I were putting that kind of money into my system I’d look elsewhere. The 700i is a terrific integrated amplifier and, honestly, probably holds its own versus the T+A in most ways. Might the T+A edge it out in certain respects? Sure, but I’d have to hear a clear advantage in favor of the German amp before spending that kind of money, and I’m not confident that’s what I’d hear.

If it were me, and I had the space, I’d look at separates -- a power amp and a preamp. That’s probably the best way to get a sound-quality upgrade commensurate with the money outlay we’re talking about. So that’s what I would do, but I’d love to hear back when you know what you’re going to do. . . . Jeff Fritz

To Garrett Hongo,

I read your reviews with interest. I’m currently looking for a mono cartridge, and trying to read between the lines, you seemed to like the Ortofon Cadenza perhaps a little better than the Miyajima Premium BE? How would you characterize their sonic differences? Is the Miyajima bolder/more robust? Any other recommendations around this price point or a little above, but not in the $3k-$5k range, which is too rich for what I want to spend?

Many thanks
United States

Thanks for your question and appreciation of these two old reviews of mine on mono cartridges!

To answer you truthfully, “it depends.” If your mono collection is mainly of contemporary reissue material, I can heartily recommend the narrower, line-contact-stylus Ortofon Cadenza Mono cart. If you have more vintage LPs dating from pre-1958, I’d recommend the larger, oval-profile Miyajima Premium BE cart.

For a cartridge equally adept at both eras of LPs, though, pre-’58 vintage and contemporary reissue, I recommend another cartridge completely -- my reference Miyajima Zero ($2150). Mind you, I still have the Cadenza Mono and also an Ortofon SPU Mono CG 25 Di MkII cart and its companion dedicated step-up transformer. I listen to them all. But the Zero is my all-around. I think you’ll be happy with it.

There are also two other versions: the Infinity version that’s $3375 and a 78rpm version for $2250. . . . Garrett Hongo

To Jeff Fritz,

Thanks for your great review of the Auralic Vega G2 DAC. I have had one in my system for a year and am in firm agreement with your observations.

I did take the plunge and added the Leo GX clock. I wanted to demo the unit and see if there was any noticeable difference. I don’t want to disappoint you, but the improvement is just night and day -- as great as the G2 was over the Comet that I used previously, [this is an even greater improvement].

I don’t really understand why, but there is even more clarity and air around instruments, yet the musicality is front and center. Too often I have auditioned equipment that is claimed to be revealing, only to hear that etched, clinical presentation that drives me from the music.

The Leo GX is a revelation and worth an audition. You have to change the interior clock cable in the Vega G2 to use the Leo, but otherwise, it just fits in.


To Jeff Fritz,

I trust you are keeping well. If you were in my place and ever got the itch to upgrade from [my Rockport Technologies] Avior, what direction would you take? I am considering the Rockport Technologies Cygnus and the Tidal Contriva G2.

South Africa

Those are certainly two fine loudspeakers you’re considering. They are both topflight full-range floorstanders, and neither could be considered a bad choice by any means. That does not mean they are interchangeable, however.

The main difference will be in the tonal balances presented by the two speakers. In short, the Cygnus will sound fuller in the bass, and perhaps play a touch deeper into the low frequencies. Rockport is known for its generous bass response, and the two 10” woofers in each Cygnus are very capable in this regard. And although the top end of the Cygnus sounds more open than Rockports past, it will still sound a tad subdued when compared with the way many speakers present the treble. On the other hand, the Contriva G2 will sound more precise, with more finely delineated images placed on a more pinpoint-precise soundstage, due in part to the perception of increased treble information. The Contriva G2 will sound more airy and holographic in the highs, and faster in the bass.

These two speakers are both built to the loftiest standards, and are engineered to the highest degree possible. In those areas they are more alike than dissimilar. However, both products reflect the priorities of their designers, and which you’ll gravitate toward is very much a personal choice. Good luck and let me know what you ultimately choose. . . . Jeff Fritz

To Garrett Hongo,

I read your review of the Esoteric K-05X on SoundStage! Ultra. Thank you and great job in comprehensively covering a complex machine. I had an impression that the Mac is not compatible with Esoteric DACs. Did this change only with the K-05X and its siblings, or could the earlier K series (without the X factor) also have Mac-based feeds? And how was the setup process with a Mac? Many thanks for your attention.

Best Regards,

Thanks for your question. I’ve no knowledge of or experience with how the prior Esoteric K-series DACs may have interacted with Macs. But, as I wrote in my review, even Esoteric acknowledged that the K-series DACs prior to the K-05X tended to fall more on the analytic side of the sonic fence. It’s why the X-iteration came about. That said, setting up my Mac was a cinch.

The K-05X has now gone through yet another iteration in the K-05Xs, said to be even more smooth-sounding without loss of detail. But I’ve not yet heard it myself, much as I was tempted to buy it outright. . . . Garrett Hongo

To Jeff Fritz,

I’ve been reading your articles for quite some time now, and was hoping I could bother you with a question. I have been gradually upgrading my system over the past year and it’s time to get new speakers. My current setup is a pair of B&W CM9 [speakers], ARC DS225 [amplifier], and an ARC SP20 [preamplifier], so I’m sure you’d agree that my speakers have fallen behind. I’m looking in the range of $10-15k [per pair] and have been eyeing a pair of B&W 802 D2s, but have always been really keen on Wilson Audio, so their Sabrina would be a consideration for me. Alternatively, I could also hold on a few more months and shell out the $$ for Wilson’s Sasha 2s. What do you think? I am open to any suggestions! Thanks in advance!

Kind regards,
Dan Nathan

I’d expand your horizons some, Dan. If it were me, I’d look toward some other brands -- you’ll find that there are some outstanding models out there that may have flown under your radar. Here are the brands and models I’d try to hear if I were in your shoes.

Since I just purchased the Vimberg Tonda, and am thrilled with my set, I’d suggest you look into the smaller Mino. The Mino is still a three-way speaker and is built to the same high standard as their larger stablemate, but is better suited to mid-size rooms. A pair of them will cast a soundstage the likes of which you will not believe is possible until you hear it in person. The Magico S3 Mk.II would also be a fine choice. This three-way speaker has the proprietary drivers Magico is known for and, as a result of these fine drive units, is super resolving. Another solid choice would be the Rockport Technologies Atria II, which features the company’s new waveguide-aided tweeter for an open, expansive sound (not to mention that great Rockport build quality). Lastly, I love what Focal has been doing with their Sopra line -- this is another beryllium-tweetered speaker series that sounds sweet yet detailed, and of course the styling of the models is great, too.

In summary, get out there and hear some new stuff. And keep in touch -- I’d be interested to know what you eventually choose. . . . Jeff Fritz

To Jason Thorpe,

A brilliantly written review. From your review, I see we have a few things musically in common, one being enjoying “The Musical Box” at the Danforth Music Hall. I can’t help but write to suggest you watch at least the opening of a recent Nicolas Cage film called Mandy. It’s a pretty violent horror film and may not be to everyone’s tastes, but you may find the first few minutes interesting.

Thanks for sharing your audio experiences.

Mike Brown

Thanks very much for the high praise, Mike. I’ll check out that movie on your recommendation, although my tolerance for horror movies has diminished since I became a father. I’ll try to get through it! . . . Jason Thorpe

To Jason Thorpe,

Very nice review of the Vivid Kaya 45 loudspeakers. As a Torontonian now living in California, I enjoyed the Canadian references throughout the review.

I wonder if you can give me a little bit of advice. I am narrowing down on three speakers for my smallish office, 12’L x 11’W x 9’H: Paradigm Persona 3F, Vivid Kaya 45, Yamaha NS-5000.

I have heard the Paradigm Persona 5F and feel that the smaller Persona 3F with an Anthem STR preamp with ARC3 DSP would work. The same preamp [paired] with Vivid Kaya 45 [speakers] -- I am not sure because of the side-firing woofers. I have not heard the Yamaha yet since it is not available yet in the USA, though I understand it may be in the summer. I may come up to Toronto to have a listen this summer whatever the case.

I have heard the Vivid Kaya 90s, and liked them a lot, and the Vivid Kaya 45s are supposed to play in smaller rooms and can be placed closer to the back wall, due to the canceling of some of the rear sound waves.

My office is treated with acoustic treatments and it sounds real good now. Can you give me some feedback as to whether the side-firing woofers are a bad choice for such a small room?

If you have heard the other two speakers on my list, do you have a favorite amongst the three?

Manoj C.

Dimensions of 11’ x 12’ x 9' make for a fairly small room for the Kaya 45s -- it's also quite square. But if you do have it well treated, you might be fine. Also, if you’re using Anthem Room Correction (ARC), you may well be able to ameliorate any nasty standing waves. I also don’t believe the side-firing woofers will cause any problems, since low-frequency sound waves are so long, though the only way to be sure is to listen to them, unfortunately. I also suggest you contact Vivid themselves, as they can likely give you some further insight.

Regarding the Personas -- at the Toronto Audio Fest this past year, I had a chance to hear the Persona 9H loudspeakers driven by the Anthem STR integrated amp, and they sounded fantastic, so I think you have a hard choice ahead of you.

I also had the chance to hear the Yamaha NS-5000 speakers, but they’re large boxes, and might well overpower your room. But again, maybe ARC will be able to help.

In the end, though, if it were my money, I think I’d choose the Vivids. . . . Jason Thorpe

To Hans Wetzel,

I’ve read your article about the Gryphon Diablo 300 and you wrote that you used Sonus Faber’s Venere S to test, among other speakers. I want to ask if [the] Diablo 300 and Venere S speakers were a good match? I got the Venere S speakers and am going to change to the Diablo 300 or the T+A 3100 HV. Home demo is not available in my country, so I’m [wondering if the] Diablo 300 would be a good match for my Venere S speakers. Thank you.

Hieu Nguyen

I think Gryphon’s Diablo 300 is a fantastic amp, and with its massive power reserves, would work well with just about any loudspeakers, including a pair of Venere Ses. As you can tell from my reviews of both the Diablo 300 and the Venere S, products that I used in tandem with one another for each review, I certainly liked what I heard. I think you will, too.

I will say, however, that the Diablo 300 is probably overkill for this application, as is the T+A 3100 HV. Something like Gryphon’s Diablo 120 or T+A’s PA 2000 R, the latter of which I reviewed back in 2016, should have no problem driving the Venere S speakers to their full potential. With a 90dB efficiency rating and a nominal 4-ohm impedance, the S should be a breeze for either amp to drive, since each offers at least 200Wpc on tap into a 4-ohm load and plenty of current. Personally, I’d opt for one of these amps and pocket the difference for upgrading my DAC, turntable, or speakers going forward. Should you decide to plump for the Diablo 300, however, you can be secure in the knowledge that you’re buying one of the very best integrated amplifiers out there. Good luck! . . . Hans Wetzel

To Howard Kneller,

Thank you for your very insightful review of the Furutech cables and connectors.

I am in the process of changing my power cables and I’m strongly considering the FP-TCS31 as my bulk wire of choice. I currently already own the FI-28(g)/FI-38(g) AC and IEC plugs that I intend to use with this cable. I require ten cables in my system, so the choice is a big one and I cannot change my connectors to the NCF version at this point.

You briefly mention these FI-28(g)/FI-38(g) connectors in your review but I was hoping to get some more clarity. How would you rate the power cords’ performance with these connectors on them? I basically like a very open, transparent, and fast sound and wanted to see whether you think that combination would fit the bill.

If you have any other recommendations regarding bulk cable from Furutech or any other manufacturer I would be glad to have them.

Thank you.

Best Regards,

Thank you for your e-mail and kind words about my Furutech review. The company’s FP-TCS31 bulk power cable, which uses the Alpha PC Triple C conductors, is an excellent choice considering your sonic preferences. With the FI-28(g)’s and FI-38(g)’s gold-plated connectors, you may find another Furutech choice for bulk cable, the FP-S032N, for example, to be a bit too warm sounding and bass heavy.

I am not looking to have you spend more money, but do not forget the absolutely crucial role played by the AC wall outlet. I suggest your power products be from only one manufacturer, whichever one you choose. Sticking with Furutech, you may like the GTX-D NCF outlet, whose rhodium-plated conductors may also give you just what you are looking for.

Note that too much of a good thing can be just that. Sometimes, no one power cord or wall outlet works best in every area of a system. You may have to experiment with several products to obtain the balance that suits your sonic preferences. I would therefore take one step at a time.

I hope this helps. Please let me know how it works out. . . . Howard Kneller
