Yes, I think that's what it is. I must say, though, that the Lab.Gruppen is a temporary solution. I haven't had time to dwell too much into various power amp options, so I grabbed the IPD 1200 that was offered to me by the local dealer to very favourable conditions. But I'd like to switch to an analogue amplifier at one point. I am sure, the GSX-Mk2 pre-amp will pair well with just about any good power amp. Right now, I am pretty happy with the current setup.
