Favorite 300B: Sophia vs KR

Gsm18439: RAM Labs and Tube Audio Store are one in the same. There are only two EML US dealers I am aware of.

Phaelon: I think you'll be satisfied. I'm confident I will based on my dealers insight. I used Sophia 274B in the past and they were very impressive, even against some revered 40's/50's NOS 5U4G's.

I'm sure the EML, KR, and EAT have something to offer as well. I read some very positive comments in the past about the EAT 300B. Just beware of tube specs/amp compatibility.

Would be interesting to read some of your impressions.

Update: It's still early to judge, but I like what I'm hearing. I thought I would. Only one problem; there was a noise issue with one tube so Sophia generously replaced with a free upgrade to the ceramic base. And unfortunately to my astonishment that pair seems to have an issue also (one channel is louder then the other, or possibly the other is lower in volume). All I know is that the loudness is unbalanced between L&R channels and it follows the tube when switching between monoblocks. Sophia wants me to give it 100 hrs and hear if it changes. Otherwise, replacement #2.

I ordered a matched quad. Setting the bias of my amplifier to its minimum setting, I still can't achieve the amplifier's recommended bias. Sophia said they are willing to test for lower emission tubes to meet my amps specs, but that these tubes will actually be more satisfying. I'm trying to do a little research that will aid in my decision.

My amps have no manual bias control. Did you order the Black or Ceramic base?

I want to add that Sue at Sophia has been most gracious and accommodating. If this were KR or another I think the situation would be quite the opposite. ;-)
