What LPs do you use for VTA adjustment
"On my Shelter 901 changing arm height by .04mm or less makes the difference between being in this sweet spot or not." Doug, do you set the VTA for each record in your collection? 0.04mm is 0.002". I measured the thickness of some of my records la... 
Top phono cartrige to match jfrech's system ...
"just a little cool in the midrange, just a little hot on the top end and images could be a little rounder"I've never used the Amperex 7308s in a phono stage, but I do have experience with using them in a line stage. If that is transferable (I don... 
ikeda mc-transformer
"Any additional stage in the signal chain reproduction ( it does not matter the quality of that stage ) degraded the quality reproduction of this signal. Period." You said it. My point exactly. If you don't use a transformer then you must employ e...

And an extra active gain stage does NOT add extra noise and distortions? What planet are you living on? 
Is there a worthy 6922 presently made?
BTW, I payed $40 recently for a USA 'pinched waist' that is 'phono grade', clear markings, and the original box. I agree that $800 is 'way to much' to pay for a pair of these tubes. Also, regardless of what the seller on Audiogon said, I think the... 
Is there a worthy 6922 presently made?
It's the current OEMs who dictate the market and they do put a lot of price pressure on the mfrs. of the tubes. They can and do take measures to cut costs. Also, don't forget all the many specialty chemical suppiers who back in the day provided th...

John_tracy: Billions and Billions of 6DJ8? If that is factual there is no scarcity of NOS tubes and the price gouging is even more reprehensible. Where are they?I said: Billioins and billions of 'tubes'. Not 6DJ8s. If you just take the # of TVs pr... 
Is there a worthy 6922 presently made?
I've been accused (I think) of being a NOS snob. But look; in the 1950s when the 6DJ8 came into being, it was designed to be used as an RF amplifier for the -then- new UHF TV band. That market was HUGE! Billions and billions of tubes. Companies ha... 
Is there a worthy 6922 presently made?
I have both USA and Holland 'pinched waist' Amperex tubes and $800/pair is probably excessive. Anyway, they are too bright in my system; all amperex tubes are. They actually hurt my ears. I believe it's called tweeter burn. What seems to do the tr... 
TT setup woes
That's where I am heading. In the initial setup I had the cart. loaded with 300 ohms. Probably to kill some of that shrillness. Last night I was listening to the new Peggy Lee release, Latin A'la Lee and switched to 100 ohms. Bang! Peggy Lee start... 
TT setup woes
Thanks for all your help. Patrick, I did use HiFi News test record to reset the anti-skating bias. Tom, since the inside of the collett was fitted to a mandrel that was cut to fit on the lathe, the machining to the outside SHOULD be perp. to the p... 
Best tube AM/FM tuner
I have a modded Fisher 100b. VTV rated it a best buy in their tuner survey. They can be found on ebay for less than $200. New oil coupling caps, hexfreds in the power supply and a good tune-up and you will have a sweet sounding tuner. Also try a g... 
Which Dac is more "Musical Sounding" ???
I can't speak for the Kora having not heard it; but I can very much recomend the A21. I set mine up last Sat. and out of the box it impressed me. The first time I had a sound stage with CD (3D rather than 2D). Very analogue like. I have an all tub... 
Good Phono Pre-Amps...$500 to $1500
K&K Audio Phono Preamp kit. $1500. It will compete with the big boys. 
more help with vinyl..
If you are using a MM cart. loading is critical for reducing surface noise. Capacitance in parallel with the inductance of the cart. results in a high freq. resonance around 19K for typical cart. and 200pf cap. Ultra-sonic noise will excite this r...
