Wow. That's cool. New power suppling looking like the WA7. Can't wait for more information.

Thanks to Warrenpchi, this was my hotel room rig in LA. Suffice to say, the sound quality was excellent.

Anyone who uses the HD800, do you find HI or LO gain to be more suitable?

That's actually an impedance switch, not gain. Changes are rather subtle, mostly in the low frequencies. Hi-Z sounds more natural with the HD800 - the bass is fuller, with somewhat longer decay.

Ah yes impedance (no idea why I said gain). Yes I've noticed with HI-Z it sounds less 'veiled' than Lo-z

how is the treble change? on the low/high impedance, subtle? ofc with the EH Tubes.

This is harder to tell as when you switch impedance there's also a slight volume change. Overall the HD800 sound on Hi-Z is more extended. Highs on Lo-Z are muffled, but not to extent that would make it unlistenable. 
Using EH cryo tubes atm.

So what's the word on this tube power supply. Vaporware? Actually going to ship before Armageddon?

I talked with Jack Woo this Saturday in Babylon.....  Told me he is still working on it but its close to production... He told me the additional cost will be around the 350$ range.  Also the optical option will be around a 200$ish option.

I heard it at Babylon yesterday with stock and Sylvania 8514A tubes and bass became deeper with 8514s

Anyone with a lot of time on both the stock tubes and the EH 6c45 Gold plated pins?  Do the upgraded tubes make much of a difference?
I have a pair of cryo treated Sovteks from Tubeman I use and like.  I have read mixed feelings on the EH gold pins.

 

[olegausany]

I had over 300 hours on EH tubes and really enjoyed them , never looked back to stock ones

I have 100+ hours on the EH and have been using the cryo's from tubeman for a couple of months. I really like the cryo's - deeper bass and a bit smoother than EH. That said, the EH is a bit more detailed and also a great choice. Both of these beat the stock Sovtek imho.

Thanks for the answer.  Going to stick to the cryo's for awhile.

hmm woo posted the tube power supply on twitter. officially calling it the WA7tp.
 
was hoping for more details but that looks like its it for now.

at the socal meet the prototype was a push button to turn it on and off. i was hoping it'd be a turn knob to switch on and off but based on the pic, it'll be a push button still.
