Does anyone care to ask an amplifier designer a technical question? My door is open.
I’d like to add this: I appreciate the fact that there are two professionals contributing here, despite the fact that there is tension that’s been created by disagreement. I’m trying to read through the commentary to the points being made, the exa...

Haha... Nimble Tube-Roller Society! That exchange must have been just before I started buying stereophile (1986). I agree that having the freedom to choose different power tubes for the same amplifier is liberating from an owners standpoint (well,...

What prompted my question regarding tube types was the discussion in this thread about 6sn7/12au7/6sl7/5751/12ax7 tube type use for preamps and amp inputs. But there is also the question of power output tube choices - el34/6550/kt88/kt120/kt150, e...

What causes a designer to choose a certain tube type for an audio circuit? Is the circuit designed around a specific tube, or is the best tube type found for the circuit that’s been/being designed? I know there are different electrical properties ...

@ramtubes. I’d like to personally thank you for taking the time to sift through all these messages and provide your input on many of them. There’s a lot of valuable information here. I’d like to thank @atmasphere as well! Differing viewpoints give...

I wanted to weigh in on the power cord debate. I purchased a few of them several years ago. I did it because so many people were raving about how great they are, including one friend of mine in particular. When I replaced my stock cables, I did so...

@ramtubes. I will measure the Axiom with a meter. Actually, after considering your comments regarding my experience with the passive, I reinstalled it in my system. This time I reduced the gain of my phono preamp, and I’m giving it another go ‘rou...

@clio09. I believe bdp24 was suggesting I consider having Roger build me a passive (for switching and level control), not a phono preamp. In addition to an input for phono, I’d like to have at least two other inputs, and preferably two outputs as ...

@bdp24.  I’m thinking that may be exactly the avenue I’d like to explore further. I’m looking at phono preamp options as we speak. I have a very simple passive device, which I did try, but didn’t care for. I am very willing to try other passives t...

@bdp24. All understood. Thanks. I guess the trick is to figure out what’s causing it, why it’s happening, and how to fix it. That’s what I’m hoping to learn more about. I believe that my speakers, my amplifier, and my vinyl playback system are bet...

@bdp24 .. I had an older CJ preamp, a PV-8, which sounded as you describe. I replaced that with this one, a Rogue Perseus Magnum. It improved on the sound I was getting from the PV-8 in some areas, but I also felt like there was something missing ...

@ramtubes. Thank you for your reply to my questions.You asked: “If you have a good preamp, why change?”. I’ll list a few things that have me looking elsewhere. 1.) I bought this preamp new, and after about two years it developed an issue. Every fe...

It doesn’t make sense to me that some people get so angry/defensive/personal/nasty when discussing audio equipment! It’s fascinating in a way, but doesn’t do much to educate anyone, and most certainly impedes oneself from getting an education. I l... 
Does anyone care to ask an amplifier designer a technical question? My door is open.
@ramtubes. I’m not ready to abandon passives from one less than favorable experience. The passive I have is a Luminous Audio Axiom... one input, one output, and volume pot. I listen to vinyl 95% of the time, so I was feeding it from the output of ... 
Does anyone care to ask an amplifier designer a technical question? My door is open.
@bdp24 That's actually a good suggestion, and easy for me to do, and I have no good reason why I haven’t. I had a Forte model 4a for awhile as well (50 w class A), but never tried that on Maggies either. I have different systems in different areas...
