Newb Tube question
Caveats, in relation to "tube rolling".  First, in my experience mediocre sounding gear does not become wonderful sounding gear via tube rolling.  If you don't like the sound of your preamplifier, don't expect to transform it by buying expensive "... 
Went from brilliant to distortion
desalvo, Do I understand correctly that you replaced 12AX7s with ECC802?  The ECC802 is equivalent to a 12AU7, which is a much different tube electrically, compared to a 12AX7, as noromance already suggested.  You made some remark about needing mo... 
Right channel makes raspy noise when playing records
Microphonic tube.  Yes. 
ifi iPhono 3 "Black Label" Anyone?
Thx guys. My conflation of your separate opinions is a product of reading on my cell phone. 
ifi iPhono 3 "Black Label" Anyone?
Based on the classic geometric proof, "things equal to the same thing are equal to each other", can we infer that you like the Allnic H1202 better than the ARC Ref 10 and the Zesto best of all, so far?

Robert, please define “optimizing the left and right channel high frequency response “ for frequency >20khz and how you would do it. Thx. 
Pioneer Direct Drives - Now and then?
twoleftears, Clearly, you are correct.  The SL1200 Mk7 does have a coreless motor.  Basically, I couldn't imagine how they could sell it for so little and still retain the coreless motor, or why that would be a wise marketing decision.  Anyway, th... 
Pioneer Direct Drives - Now and then?
Helomech, seems like you have an intuitive understanding of what Herb Reichert might have meant when he used the term “forced weightiness”. I do not. Sounds like nonsense to me. So if you could expound on what you think it means, I’d appreciate it... 
Pioneer Direct Drives - Now and then?
helomech, Was interested in your comment about "forced-weightiness and digital-like glare typical of DD tables".  Would you care to back that up? Exactly what turntables have exhibited those qualities in your system?  And can you define "forced-we... 
The Hardest Naturally Occurring Substance on Earth
If you have a decent LP collection, you might play any one particular LP 4-5 times a year, if it's one of your top favorites.  On the other hand, every second of listening to LPs is courtesy of the diamond tip tracing a groove.  Compared to any si... 
Is there an ideal (ish) cartridge output?
While I would agree that low moving mass is a desired quality in a cartridge, it cannot be the whole story. And if low moving mass per se is the major goal, then there are moving iron, induced magnet, and other types that inherently have lower mov... 
Is it really worth it to get a phono stage over $10k
+1 for Dave Slagle. He is also a designer of EMIA, mentioned by Mike Lavigne. 
Is it really worth it to get a phono stage over $10k
I think you can certainly do better than your current AI preamp, and you don’t have to spend $11.5K to achieve that goal.I personally am not a huge fan of John Curl phono stages I have heard, but that doesn’t mean you need to be restrained by my o... 
Minus k Technology BM-8 Isolation Platform
In my opinion, minus K or the Vibraplane are superior to any of the built in suspensions in the turntables that you named. But realize that you should not use an independently suspended turntable with an outboard suspension system like the minus K... 
How does Shure V15 Type IV compare?
I never was a big fan of Shure V15, in any iteration of it.  Not compared to any cartridge that is among my top 10 or so.  I used a V15 for years in the 70s, along with my AR-XA turntable; that was the standard set-up for middle class audiophiles ...
