I've got a Woo Audio WA3-based custom made preamp, and the other day I noticed that there was a bit of a transformer hum coming from the unit. I discovered the hum by accident... I bent down to pick something up by my equipment rack, and my while I was bent over my head was really close to the preamp and that's when I heard the hum. So I don't know if the hum has always been there and I didn't notice it, or if it's a new thing. Do any other WA3 owners notice a transformer...

I have to laugh at the people that are chiding the poster for being impatient and for making his concerns about his dealings with hifikanon public... it's that type of enabling attitude that allowed Singlepower to do so much damage to the participants of Head-Fi. So thank you counterpoint for sharing your experiences with us in your dealings hifikanon, and I hope everything turns out well for you in the end.

The MPX3 was an improvement over the PPX3, but not by much, so I sold it. Now...
There are great sounding examples of both transformer and OTL amps available on the market, so I wouldn't get too hung up about it. I also wouldn't get too hung up on whether an OTL amp will cook your headphones - although I'm sure it has at some point happened, I can't recall anyone ever posting here on the boards about an OTL amp taking out a set of headphones, so it would seem that it's pretty much a non-issue. IMO the Woo WA3 OTL and the Senn 580/600/650...
In regard to the 3+ being able to drive HD 650's, I owned a 3+ and it had no problem what-so-ever driving 580's/600's/650's. IMO Senn 580's/600's/650's and the 3+ were made for each other.
