Best small signal tube for a preamp?
Keshiri, I didn't realize your Zoe came with the 12AU7's. Mine is the newer model with black side panels (a recent demo) and I believe it came with the EH 6922's. Brian at Aaudio said they have upgraded some parts in the newer model, but Lector al... 
Best small signal tube for a preamp?
Rodman99999, thanks for the comments - those CCa's are excellent (and expensive as you say), but I suspect they do more for some equipment than for others. They didn't seem to help the SF Line 3 SE too much, probably since it is already a little l... 
Best small signal tube for a preamp?
Keshiri, I ended up taking out the 12AT7's and putting back in the stock EH 6922. Based on my limited experience with the Zoe so far, the 6922 tubes seem the way to go. As HP said, it is sort of fun being able to roll different tubes; but in the e... 
Belles 350a reference fireworks
From the Soundstage review;The 350A Reference is also AC coupled, while the 350A was DC coupled. The difference is essentially safety for your system. An AC-coupled amp will not pass DC to the loudspeakers, while a DC-coupled amp will if any is pr... 
Best small signal tube for a preamp?
Hi Keshiri, I still don't have the "feel" of the Zoe, and honestly have not paid too much attention to where the volume knob is set. It is a very nice preamp, and an absolute steal for the price, and I compared it head to head with the Vibe/Pulse.... 
Best small signal tube for a preamp?
Cyclonicman, I appreciate your comments but the Zoe is specifically made to operate with the range of tubes listed above. The preamp has a SATC (automatic tube adaptation) circuit and user switchable 6V/12V plate voltage, and the owner's manual sp...

Are you sure about the phase inversion? I did not know that. I will reverse leads and see what it sounds like. Keep me posted on your tube trials. I am in the process of getting a pair of NOS Amperex 6922's to try. 
Best small signal tube for a preamp?
Yeah, I copied Joe's paper a couple of years ago and noted he doesn't even discuss the 12AT7. That is the only tube my CDP uses. He also doesn't like 12AU7, saying - "I would say this is a fairly unexceptional tube family." I found it interesting ... 
Best small signal tube for a preamp?
For fun, I just installed a pair of NOS Amprex PQ White label E81CC's (12AT7's) that I had purchased for my CD player. I had to switch to the 12V position for those, compared to the 6V position for the stock 6922's. I will let them burn in overnig... 
future of 2 channel CD sound
Agree with John that a high definition music server is on the horizon. However, I would suspect the recording and mastering process would still play a large part in the sound, and unless something changes, the variability will still be there - you...

Hi Victor, thank you for your concern with providing us the most complete information you can. I know your posts here are much appreciated, but please don't sweat the website. Building a website is like painting the Golden Gate Bridge...once you f... 
Audio Horizons TP 2.0 Preamplifier
Thanks Stltrains and others for the comments. I believe Victor is going to send a pair of the Dimension IC cables for me to try when I audition the TP2.1 preamp. I will be comparing them against my Purist Aqueous Anniversary cables in the position... 
Audio Horizons TP 2.0 Preamplifier
Can any of you guys enlighten me on the basic sonic signature of the four levels of AH cables available (Concept, Harmony, Transparency and Dimension), and whether the conductors in these cables copper or silver? At the AH prices, I would be most ... 
Finding ultra-pure water locally...
I believe John adams sunnyvale is asking about a product that has undergone an extremely more rigorous purification process than either RO or distilled water commonly available for sale in grocery stores. The ultrapure water is likely used in spec... 
Tube sound with no tubes
Spaz, you didn't tell us your speakers, but if you want a full bottom end with little to no roll-off, choose a tube pre very carefully. The Calypso's output impedance raises to about 3,500 ohms at 20hz, so even your 20K input impedance (balanced) ...
