Best 300B


Can anyone compare the new Genelex PX300B tube to either Svetlana 300B's, Western Electric 300B's, Sophia 300B mesh plates,newer KR300B tubes or Electro Harmonix 300B's.

From my experience the Svetlanas sound a lot like the Western Electric 300B reissues. New KR300b's are better than the older KR VV32B's, KR VV300B's or KR VV302B's and all the above are better than Electro Harmonix 300B's

My Sophia Mesh Plates sounded very good in my Manley Retros but after several listening sessions I put them back in their boxes because the bias kept changing at the recommended setting. Whenever I get around to it I'm going to compare them to others in one of my self biasing amps.

Thanks in advance,

Gsm,
Yes, I have to agree with you, depending on the 300b I can significantly
alter the sound of my SET amplifier. It makes sense when think about it
however. Very simple and direct circuits with a low number of parts used.
Each 300b is exposed virtually bare to reveal its sonic characteristics. I've
been fortunate enough to have heard 10 different models of the 300b and
everyone of them changed the amplier's sound noticeably. This is a
testament to the innate transparency of a good SET circuit, pure and
natural. Gary, you having a back up Takatsuki pair makes perfect sense to
me. I'm listening to my Takatsuki as I'm typing this. I rotate them and my
EML XLS every 3 or 4 weeks.
Charles,
There are obvious problems associated with execution of the following proposal, but it almost seems as if there could be a huge demand for a vacuum tube lending library, or perhaps a tube co-op. I'd be willing to spend 1-2K on a pair of 300Bs, but I would certainly like to have assurance that I have invested in the tube that I found most satisfactory. I know some of you have a couple of flavors that you retain and use on a regular basis, but not many people are going to pony up for a pair of NOS WEs, an EML, Sophia RP, a WE replica, etc, just to run the experiment.
Brownsfan: What you say makes sense. Especially a lending library. It would be great to be able to try a tube before buying a pair or a quad. Especially at today's prices for top-notch 300b.
Of the 10 different 300bs I've heard in my system, 5 of them were graciously loaned to me from fellow (trusting) audiogon members. There are good folks on this site. Bill, your idea is a good one, it's hard to know if you'll like something without actually hearing it yourself. Other's opinions only go so far even if their taste are similar.
Charles,
I once asked the US distributor/seller of Takatsuki if I could borrow a pair to try. He laughed at me.
