From someone who has had both of the popular OTLs in his system, I will tell you that it is truly a personal taste issue. The Atmas and the Joules are great matches and a lot depends, IMO, on ancillary equipment and whether you prefer vanilla or french vanilla. By this I mean that they are more similar than different in their immediacy. I found the Joules had a slight bit more emotional impact and the Atmas were faster and more dynamic. If you have a balanced pre, its a no brainer to me, Atma all the way. I did not at the time and after having both in my house for some time, I ultimately settled on the Joule but went to a slightly faster cable than the Cardas GR, which I found to be a great match w the Atma. I would upgrade the speakers and then consider the amp next. OTOH, if you find a killer deal on a great OTL, I would jump on it. YMMV.
