Once again WA7tp is power supply which replaces stock power supply included with amp. If you own WA6 you don't need WA7tp. Your way of upgrade should be WA5 or WA2 or WA22. I only heard WA6SE only once at the meet so can't comment it's worth to upgrade to it from WA6

All of this is good to know. Thank you. I will look into the WA2 and the WA22. The WA5 is, I think, a bit out of my price range.

So rather subjective question but I've been eyeing an upgrade from my Bifrost/Lyr and have been looking at some of the Woo amps.  For ~ $1400 is the WA7 + WA7tp going to be the better amp than a WA6SE or WA2 if I continued to use my Bifrost?  Currently running some AKG k712's with my eyes on the HE560 sometime soon, or maybe LCD 2's.  
 
Namely I'm wondering if the WA7 amp is as good as the WA6SE/ WA2 if I disregard the DAC portion?

Ordered the wa7tp and I ordered a pair of ECC802s gold pin tubes from eurotubes.com. These are long plated ones so they should have a fat, thick tone.
Can't wait to try them out when my wa7tp arrives!

Very nice I will also post impressions once I receive mine,
as I attained the Sylvania 5814A 12AUs matched pair to swap once I get it.
These were the tubes that gave more bottom oomph when I listened at the NYmeet..

Are the specs for the WA7tp available anywhere? I checked the Woo Audio website, but didn't see anything.

I would like to see what differences besides the tubes are there and what is going on...

It is giving more power or current or higher voltage swings or maybe the tubes are doubling as a filter or storage with their hot cathodes spilling those electrons in the tube vacuum?

Or maybe there is some kind of right/left channel separation? How is this supply designed?
What's inside that Lil box!
Fairy dust? Lol

These are rebranded 12au7 tubes , the tubes being discussed are specifically 5814a which has a slightly different spec to 12au7

I have a question. .
The woo wa7 is rated a max of 1W @ 32ohms. .
So what differences would I encounter with the WA7TP installed?

Will we see specs and/or internals of this unit?

I know for sure there will be sonic advantages as I have herd it,
But just wondering on the technical aspects of this unit..
