Here you go, Aesthetix IO: https://www.audiogon.com/listings/phono-aesthetix-io-2017-07-25-preamplifiers-48392a1b-fe5d-450b-926... I have no connection to the seller but this is one of the finest phono stages out there IMHO. |
I've been enjoying the ModWright PH-150 Reference Phono for the past year. It's a very flexible MM/MC, 2-input, RCA or XLR tube phono stage that fits in your price range (MSRP $8K). Sounds great IMO with the stock tubes, although others have tube-rolled with good results too. Front panel controls for all loading adjustments are a bonus. Dan Wright is an excellent manufacturer and tech advisor for this product. |
In that price range, I would definitely be getting the Zesto Tessera. Some reviews out there by Bob Levi and Michael Fremer. But it has all the flexibility in the world on the front panel as well. I had the lesser Zesto Andros and was the best tube phono pre I've heard. My dealer is a Zesto dealer and feel free to let me know if you want to talk with him about it. |
Based on your system description thread it appears that the outputs of the phono stage would be driving the analog inputs of a Benchmark DAC2 HGC. The analog inputs of the Benchmark (which are only provided as unbalanced RCAs) have a specified impedance of only 20K, which will be marginal (or worse) for use with many tube-based phono stages, including some of those that have been suggested. For example, the Lamm LP2.1 has a specified nominal output impedance of "typically 2.3K," which I suspect is significantly higher at deep bass frequencies, and even 2.3K does not meet the rule of thumb guideline of a 10x minimum ratio. Also, the ARC Ref Phono 2SE has a recommended load of "50K-100K ohms and 100pF (10K ohms minimum and 2000pF maximum)," which would seem to imply that a 20K load is not ideal. Regards, -- Al |
Rhodes, from a technical standpoint the Sutherland PhonoBlock appears to be suitable for use in your system. Regarding output impedance specifically, John Atkinson’s measurements indicate "200 ohms across the audioband," which is fine for use in conjunction with a 20K load impedance. As Jond alluded to, though, the sonic quality it is capable of providing figures to be limited by the Benchmark, and I suspect also by your power amplifiers. Good luck, however you decide to proceed.

If you can find one, the Jadis JP-80 is incredible. But they are hard to find on the used market. Once you upgrade a few of the caps to V-Caps, it is unbeatable.Here’s a new one for $16,000. Another one to consider is the Coincident Statement phono stage - $6,000. It takes 4 x 12AX7 tubes. |
The groove SRX by Tom Evans (Audiodesign) is simply amazing. To me it sounds better than gear priced at 10k and it’s less than half the price. I use it with a Cadenza Bronze and it’s a perfect match (but also with my previous Denon it was good). There’s a purity in the sound that I simply love (my system also comprises D’Agostino amp and WA Alexia speaker). With your budget you can aim at his top end phono stage (the master groove), but I've never had the chance to listen to it so I cannot say if the price difference is worth the extra cost Ciao |
rhodes-if you haven't seen this listing, this Rogers tubed unit is very nice. Made in the USA! https://www.audiogon.com/listings/phono-rogers-pa-1a-tube-phono-preamplifier-trades-ok-2017-08-12-pr... I have heard a couple of systems with one, and all the expected sonic characteristics were there-and being tube, it's quiet. |
+1 for Sutherland. Ron doesn't get much press in the audio rags but he is very well respected. For your budget I would recommend that you seriously check-out his full featured preamplifier, the N1. I have owned mine for about 7 months. It combines his state of the art phono stage and his well respected line stage. Bullet proof and quite possibly the best sounding preamplifier at any price. Loosing interconnects is always good!

The N1 is in another league with no disrespect to any Parasound product. You just need to take the cover off for 2 reasons: 1) to see the build quality 2) set loading & gain for your phono cartridge. Be careful not to salivate on the circuitry! The sound is simple to describe, just gain with no signature of it's own. It gets out of the way and lets you hear exactly what's in the grooves or any other source. As I stated earlier, possibly the best sounding preamplifier at any price on the planet! |
I have had a NVO SPAII for a few years. I recently was without it for a few weeks and had to listen to my solid state phono stage instead. I can't express how much better I find tube phono stages. The NVO, I believe is one of the best. The blackness of the background is surprising, the energy fed to my preamp is unbelievable. Very full and rich presentation, and the smoothest and easiest on the ears I have ever heard. |
"I have had a NVO SPAII for a few years. I recently was without it for a few weeks and had to listen to my solid state phono stage instead." tomathome-I have been intrigued by the NVO after seeing listings years ago here, on Agon. Personally, I would NEVER have a rig without a tube phono stage. SOO many bottles in that box! I would imagine just a couple are really the "money" tubes for tweaking the sonics? Based on pictues, I wasn't too impressed with the build. Tube sockets on board, case finishing looks a little underwhelming?Sonics however....all the reviews are favorable. I would consider a used one for the right price. |
Stay away from those phono stage using 12au7s. High end tube gain stage should not use those cheap tubes w/ high output impudence and non-linear gain. High mu tubes may not Sound smooth as directly heated tubes, but at least be able to drive equalizer network w/o too much variance. Also, the real cost no concern phono stage should use inductors in equalizer. |

Also, the real cost no concern phono stage should use inductors in equalizer.I can't agree with this. First, the 12AU7 is based on the 6SN7 and has similar linearity. Their main problem (which is not an issue with 6SN7s) is microphonics. They are not particularly 'high output impedance'; in fact are often used to drive power tubes. Inductors say nothing about phono EQ one way or the other. One issue with using inductors in a phono stage is ringing; this calls for careful design to make them work. @rhodes Have you considered using a balanced phono setup? All cartridges are a balanced source and it sounds like you have an amplifier that has a balanced input. An advantage of balanced operation is the effect of the interconnect cables in the system sound is reduced. |
Btw,atmaphere amp sucks: its output impedance is so high that only speaker has reasonable punch driven by those type of otl amps is eletrostatic speaker. Furthermore ,even after extentive mod, atmaphere amps longtail differential driver stage is too weak (guess which tube number is the dtiver tube :)). |
The world is your oyster my friend - you have a brilliant choice out there: for tubes: 1. Tron 2. Thoress 3. Aesthetix 4. Manley Steelhead that's just four Solid State: 1. Whest Reference 2. Tom Evans Groove Master 3. Moon Audio (not sure model name - but amazing SN ratio) 4. Pass LAbs 5. Van Den Hul (the grail I think) you are gonna have to speak to dealers and ask if you can borrow one to plug into your system and listen for about a week or so. You are shelling out a lot of cash so enjoy the journey so to speak. If you have a lot of pre 70's records look for a stage with adjustable EQ. |

Its also quite clear that the gentleman has no idea what he is talking about as the circuit he refers to does not exist in the amp. As an example the most common speaker used with the M-60 was for many years the Merlin VSM, which is a 6 ohm loudspeaker. |
