Currently looking at Woo amps again for my beloved TH900. I used to have the WA7 before and it was fantastic with the TH900 (ended up selling it though because at the time I just was not using it much and needed to free up some funds. However, now I am in a much better place financially and am craving for a good amp to pair with my TH900.
So far on my list of possible choices is a WA7TP (previously I had just the WA7 without the tube power supply upgrade), the WA6 and the WA6SE. Anyone want to comment on how the WA7TP and WA6/WA6SE compare?

I don't know much about the TH900. So I looked it up. According to the specs it needs to be driven well.
It was interesting I didn't think the WA7 would power them well, however not only will it power it well it should do better than the WA6.
I think you could find the WA6 a little underpowered.
The WA7 doesn't have as many tube rolling options however there is a nice thread on the topic.
WA2 will be underpowered.
WA22 is what I own but it could be a bit pricey. Not much difference between the Duo WA7 combo tho. Lots of tube rolling options.
WA6SE would be my choice. Plenty of power and more tube rolling fun.
If you're referring to HDCD, I don't believe so since HDCD is a proprietary Microsoft format. Which is a bummer! I have support for Redbook, HDCD, and 24-Bit/ 96kHZ up-sampling in my modified Shangling T-100C CD player. These formats work very well when implemented correctly.
Relevant to what; are we comparing apples for oranges? A properly made 300B amp manufactured by high end company for loudspeaker equivalent and to the quality of the Woo WA5 would cost 3 to 4 times the cost. The Woo WA5 is actually a steal for this custom built point to point wired master piece!
I need to understand better exactly what the high and low impedance jacks do on a Woo amp. Is it correct to say that the only technical difference is that each jack is tapped from a different spot in the secondary windings of the output transformers? Which means that the high jack will deliver a higher voltage but with a lower maximum current? This explains why the high jack produces the same volume at a lower setting on the volume knob than the low jack. Now assuming I have headphones I can drive to my preferred volume perfectly well on either jack, is there any technical reason why there would be a SQ difference?
Let me partially answer that... I assume output impedance (http://nwavguy.blogspot.com/2011/02/headphone-amp-impedance.html) as presented to the headphones is also changed by where you take the tap? While output impedance supposedly has big effect on freq response for dynamic drivers, it doesn't affect planar drivers, right?
