Thanks

 

I assume you refer to a tube tester.

 

The settings should be in the Tube Setup Chart.

or do you mean data sheet?

Just got myself a couple of 6SN7 for comparison on my WA22 paring with LCD2 hp: Tungsol BGRP, RCA brown base, standard Tungsol clear glass, Shuguang Treasures CV-181, and Brimar CV1988 black glass.  So far the BGRP wins with it's clear, light and airy presentation, bass is nice and tight.  Switching from it to the RCA brown base I can feel that the music got heavier, slower and overall thicker feeling.  The Tungsol clear glass is a bit better, but sounded dull compared to BGRP.  The Treasures is closer to BGRP but still falls behind slightly with its grainier/dryer presentation, but over all enjoyable.  The Brimar is the closest and I would choose its or BGRP depends on the mood, the Brimar is a slower, but feel smoother than BGRP, I like Brimar better for vocals and BGRP better for classical.  One thing I noticed is that the BGRP has a tad, just a tag, higher noise floor than the rest of my 6SN7s, noise disappeared once you the music started, even between songs I don't really hear it, but it's higher.  The Treasures has the least noise of all my 6SN7 tubes.

 

Are my observations consistent with that you guy are hearing?

I have the TSBGRP & TS clear glass with WA22 & my experience is similar to the above expect I do notice any noise floor with TSBGRP.

I got these couple of days back & have been in awe since then.This for me is the undisputed King (I know it is not a 6SN7 but as it is a drop in replacement in most 6SN7 amps I am posting it here ). I will not use any adjectives as all the good ones are applicable to it, I have decided to stop buying anymore 6SN7 or equivalent tubes after these, I feel no need anymore, I have reached my destination :). (please see my profile for my 6SN7 collection).

What is it and where can I buy it?

post #4087 of 4214

Mullard CV 181, these have the most crazy prices amongst 6SN7 (& equivalents) , I searched for these almost for 3 months before I could get them within my budget. Considering the fact that these have killed anymore urge for 6SN7 tube rolling (I had around 4 pairs of 6SN7 on my Ebay watch list to buy, which I have now promptly deleted), I consider it money well spent :D.

post #4088 of 4214
Hmm how much did you paid for the pair? Any recommendation on where I can get a pair? My quick search didn't show up any lead. Thanks
post #4089 of 4214

I got it on Ebay for $ 450 pair ($390+60 shipping).

That is a bit steep for me especially after the ts bgrp. I'll watch out for it when my wallet recovered. Thanks
post #4091 of 4214

Yes, I know. It was a more difficult decision for me to buy this than the decision to buy WA22  , but it is a diff amp now so dynamic & fast.

I got RCA VT231 Grey glass from *Bay, plug to my SET 300B as input tube replace the Sylvania VT231 brown base.

Sound of the grey glass more warm, nice but loose detal and high...sound litle bit dull in my amp.

 

I change my interconnect (ic) cable from DAC to amp to Analysis Plus oval, I always use this IC when system feel dull.

The amp sound more detail, vocal of Ingram Washington more pleasant.

 

My personal opinion, the grey glass is perferct for vocal ; warm but soundstage not wide as Sylvania VT231 and lose details..

For all round music I prefer Sylvania VT231 brown base;wide, deep,detail
