Audiophilism is a hobby
True! I was listening yesterday to one of the first all-digital rock albums Peter Gabriel's Security. I had the original CD in a vintage 16-bit player and was amazed by the vividness of the sound quality!  I felt what I was hearing was the master ... 
Andrew Singer Of "Sound by Singer" passed away yesterday
I remember going to one of the NYC audio shows in the late 70's. Sound by Singer had a room there in the hotel. Equipment was set up - but NO sound! Visitors commented about this negatively. Why bother setting up an exhibit and refusing to play mu... 
How can I measure the noise on my AC mains with a 2ch oscilloscope?
Your components' power supplies are designed to putput clean DC to activate the circuitry. No need to worry neurotically about noise on the AC line. Competent engineering takes care of that.  
Mark Levinson Has Saved Me And My MUSIC!!
@wsrrsw : Digital recording and playback is a tried and proven technology. The music waveform is perfectly preserved. To believe otherwise is to remain trapped in neurotic confusion! Which Mr. Levinson wants you to be so he can get your $600.

Another cure in search of a disease. An obvious money grab!  
40+ watts SET, cost is not a problem
There is a Golden Tube Audio SE40 amp available now on eBay for $1000. It uses three 6L6GC beam tetrodes in parallel per channel It is single-ended, no phase splitter. I own one. Tube replacement is far less costly than 300B's, 211's, 845's ... Yo... 
40+ watts SET, cost is not a problem
So you want an SET amp? These typically have output impedances over 1 ohm and higher. Due to interaction with speaker impedance the result is a non-flat frequency response (Ohm's Law). The typical SET amp acts as a tone control as it tracks the sp...

"...silver takes away something from the flow and harmonics." LOL!  Another opinion not supported by Material Science.  
Could Class D really be that good?
@thecarpathian :  $149 with the 48 volt power supply. Yes, it is built with good parts.   
Could Class D really be that good?
A well-engineered product using the TI TPA 3255 power chip!  
Could Class D really be that good?
A simple upgrade is to order the Fosi with the 48 volt power brick. Go to ASR to read the recent test report.  
Can anyone recommend a new or NOS 300B or 805 vacuum tube?
If you don't want Chinese then there are the European companies like JJ, Sovtek, Gold Lion ...  
Can anyone recommend a new or NOS 300B or 805 vacuum tube?
Linlai  makes good tubes at reasonable prices! Don't fall for the belief that only premium priced tubes will do.  
300B SET Amp driving Wilson Sabrinas
@mijostyn +1: A 7 watt SET amp has a really limited dynamic range unless you have Klipschorns (100db sensitivity). To hear an appreciable increase in loudness with the Sabrina's an amplifier of at least 70wpc is required. 10 x the wpc = twice the ... 
how to fix a CD player
The transport mechanism rides on rails. These require lubrication - lithium grease. My old Pioneer has the same problem - it gets stuck a few minutes into all CD's. I will have to buy some lithium grease and lube the rails so the transport can tra...
