Need tube help with tube buffer 6SN7 tubes

Hey guys,

I just got a Yaqin CD3 tube buffer. It came with a pair of chrome top (I believe) NOS tubes that were labeled as follows:

JAN 6SN7WGTA

Philips ECG 8626

34167 USA ADC

I'm not going to comment on the effects of the tube buffer yet, except to say that I have heard a difference. I would like to get another set of tubes and was considering a pair of Sylvania Bad Boy tubes. I'm considering these tubes for no reasons other than that I've read good things about them and they are reasonably priced at under $100 for a matched pair.

I'd appreciate any comments regarding the tubes that I have and those that I am considering getting. I'd also appreciate comments or recommendations regarding alternatives. What I'm looking for is a good "all around" tube.

For what it's worth, I'm running an NAD C162 pre, Aragon 2004 amp, Emotiva XDA-1 DAC, Squeezebox Touch (fed by NAS), Paradigm Studio 10 speakers and a small REL sub.

Thanks.

In my experience, tubes used as buffers have much less impact on the sound when compared to tubes used in gain stages.

BTW, the Bad Boys listed for $120/pr are not real Bad Boys. True Bad Boys have Three (3) rivet holes, the ones pictured only have two rivet holes.

Yes...true Sylvania Bad Boy can be identified by:

1) 3 hole black T plates
2)1/3 Bottom getter flashing
3) Copper grid posts
4) Silver top and bottom rectangular mica.
5) Date code of 1xx, 2xx or 3xx were 1, 2 or 3 represent 1951, 1952 or 1953 and xx represents the week. Date code is printed vertically on the tube base.
6) Full black bottom base with Sylvania or JAN-CHS-6SN7GT in green letters with the green sylvania triangle.

As for the quality of the sound when compared to other Sylvania tubes, that is very subjective, but I prefer the Bad Boys.
