V-Cap CuTF .22 on Gain Tubes-- Primaluna Dialogue HP Integrated
I also put V-Cap CuTF between driver tube 6F6 an 300B output tube in my SET amplifier. Thank a lot to @zipost who recommended me to use V-Cap CuTF in this position. Even after just 30 hours they sound very good and sound is continue to improve.I u...

A question for 45 SET experienced listeners
Hi @atmasphere ,Do you know why so many designers use 6sn7 driver for 300B and even 211 and 845 tubes?1. Do they want to achieve a special slow signature of an amplifier sound?2. Do they do it as result of lack of knowledge and experience?Regards,...

I don’t understand why some digners use 12AX7 to drive any ouput tube in SET amplifier. I also don’t think that 6SN7 is a good driver for 300b.In my 300b amp 6F6g in triod mode is used as driver.And it doesn't sound slow at all. Coincidence Franke... 
Chord Qutest + MScaler
I improved the SQ of Qutest significantly when I changed BNC digital socket to Audio Note silver RCA and started using NBS Signature cable. I also removed the original brass RCA output socket from Cary CD player (used as transport). Thank a lot t... 
Chord Qutest + MScaler
Have anyone tried Sbooster with Qutest?I have a horrible experience with 2qute and a MCRU power supply. The sound was so odd and ringing like a glass. I sold the MCRU power supply on EBay but I lost 70% the of prise.

Analogue Productions has been reissuing many of the RCA Living Stereo titles. I have a hybrid SACD of Scheherazade and it’s down right fantastic given that it was recorded in the late 1950’s.I have hybrid SACD of Scheherazade and listen it on CD. ...
