Hi Simon,
Have you heard the WA5, comparing it to your 234? I've got the first WA5 built for the market, and love it! Now, after reading all these great posts about the Elrog 300B, would like to buy a pair....was almost going to go with a pair of the Sophia Royal Princess matched 300b's, but am going to hold off for now, even though it will probably be a long time before the Elrog is available.
I am curious though, as to the sonic differences between these two amps...there sure is a huge price difference. I do use the speaker outputs, like them a lot, in fact, soon will be pairing the WA5 with a high-end 2 way speaker which has a 94db sensitivity into 8ohms.
Interestingly, my reason for buying the WA5 in the first place, was to listen to my pair of AKG K1000's, which I also like, however I find I use the speaker output a lot as well. Have not heard the Audeze, the Sennheiser, or any other high-end headphone through the WA5.....that's another audition waiting to happen.
Thanks!
