Speaker sensitivity vs SQ
@audio2design , Thank you for the link to the article.It is so sad that most audiophiles don't care about this one of the most important characteristics for speakers SQ.High efficient designs sound more alive, with better texture, micro and macro...

Spendor D9.2 vs Proac D48r
Why do you consider Spendor D series?Why don't Spendor Classical series or Harbeth?I like Spendor Classical and  Harbeth sound.I heard Spendor D9 and D7 at Montreal audio show and was deeply disappointed by their scratchy, not natural sound.  
V-Cap CuTF .22 on Gain Tubes-- Primaluna Dialogue HP Integrated
Does anybody try these capacitors?Duelund JDM Tinned Copper Foil Capacitorhttps://www.hificollective.co.uk/catalog/1-5uf-duelund-jdm-tinned-copper-600vdc.htmlAre they sound close to Custom series or to RS series? 
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...

All Spendor D line with LPZ tweeter is disaster. 
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,... 
Bigger drivers = bigger soundstage
Multi driver solution share heat between drivers and improves dynamic and decreases distortions. But it works for small derives as well for big drivers.  
Bigger drivers = bigger soundstage
Small drivers and speakers are good for marketing people:1. Better WAF2. Cheaper to built !!!3. Increase sales of expensive super powerful transistor amplifiers.IMHO the fashion and huge popularity of low sensitive speakers with small drivers is t... 
Bigger drivers = bigger soundstage
It is opposite:https://www.youtube.com/watch?v=w8jbJZq-qXc 
Bigger drivers = bigger soundstage
Smaller drivers with similar bass extension have lover sensitivity.Lover sensitivity drivers have more thermal distortion and compression. You can do nothing against laws of physic. 
A question for 45 SET experienced listeners
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.
