6SN7's
« on: May 26, 2015, 06:08:07 PM »
SO this is somewhat of a continuation of a thread regarding my new Modwright LS100 preamp/phono. I was not happy with the sound quality as ti has cheap chinese tubes in it. i have almost 300 hours of break in time on it now. I just replaced the rectifier tube with a Mullard and there was a slight improvement. But then i replace the 6SN7's with RCA Grey Glass military tubes (Circa 1944-1949). WOW that was it. This tube has glorious midrange, detailed highs and decent bass. It really has it all. I would highly recommend this tube. This specific tube was chosen to "warm up" the sound of my pre.

The improvement was so significant that I could notice the improvement while standing BEHIND the speakers. Granted I have hybrid open baffles  :rofl:

The improvement wasn't there until I let the tubes run in for about 15 hours.

You should go to Home Depot and spend $10 bucks and make one of those werd room audio fans  :lol:. I am not kidding they work good with open baffles like my hybrid Nola's.

  It has been awhile but any suggestions on 6SN7. Does anyone really know the sonic characteristics on the different brands ?

Black Treasure CV-181 garners consistent praise. Best one I've heard, but that was probably 6 years ago. Don Sachs recommends them for his Aikido-based preamp. ~$120ea   IME Treasure tubes are worth the money/best. Made in a commie chinese state factory.

Also the new Tung-Sol reissue (New Sensor) worth trying, cheaper than treasure.

Psvane/Grant has a couple expensive versions too. Privately owned chinese factory funded by Grant Audio - your fav  :-P

Well recently I have had tube go microphonic on me. So I ordered a set of RCA Grey Glass and a single CBS Hytron to replace  my bad tube. BTW, THE CBS is really good and doesn't get  much attention, therefore cheaper  :lol:
