Some of the small signal tubes I've been auditioning in the Elise. Should be ready to post something definite in a couple of weeks.
Admittedly, the last few weeks have been taken up by the WA6. Getting the thing to sound good became a matter of personal pride. I read the Woo threads, tried some of the recommended tubes, and the thing still sounded like schiit. Getting a GZ34 was definitely a step in the right direction, but the amp was still sounding fairly mediocre. It came with 4 pairs of signal tubes and I picked up 3 more. Yea, the sound improved to a degree, but nothing dramatic.Not to the point where I was truly happy with the sound.
As mentioned above, I tried some of the bottles recommended in the Woo threads, including the heavily recommended Brimar 5Z4GY rectifier. I'll spare you the story of its burnin, its base coming lose after ~5 hours of play and my daughter's clear nail hardener, and get to the meat of the matter - it has a very nice, perhaps even impressive, spacial presentation. No real highs, no real lows, no speed, little articulation, no weight. The audio equivalent of a feather boa.
With that in mind, I decided to try the one signal tube
less recommended by Woo owners. A 6CY7. To say that it completely transformed the sound of the amplifier would be an understatement. Music played by the WA6 no longer sounded like it was covered in fog. The amp actually had bass. Not the sort of bass you simply know is there, but the sort that rattles the scull. Still limited extension, and it's a sin of omission I can live with.
Having found
the signal tube, it was now the rectifier's turn. A story in itself that I'll continue in part-2 of Tales of the Woo.
BTW, this was this evening's setup. Actually, still is:
The DV loaded with a CBS 6SN7GT and a Tung Sol 6BL7GTA. Decided to try DT880/600 with the setup tonight. The 6BL7 responded very well, so I stuck with the cans.
