The other day I went into a local hi-fi store to see if they still had Piega speakers I could demo. Sadly they'd re-arranged their layout and cut down on the number of speakers, so they didn't have any. They did have the ELAC BS314s, which I like a lot, so I decided to demo them again anyway.
First up we tried them with some huge Denon integrated that also had a DAC. The sound was awful. I sure as heck didn't remember the BS314s sounding this bad. Switching to the Mojo as the digital source the sound was much improved, but it was clear the amp wasn't so good. The best was using the Mojo as a source to a Mark Levinson amp (I forgot to note the model, but it was $15k or so). The sound was absolutely fantastic. If I'd had longer I would have asked to plug it in to their best system and compare it with whatever DACs were on hand, which were the usual fare of Luxman and Accuphase.
There are a couple of dealers here who might allow me to indulge myself in comparisons. One of them has the most amazing horn speaker rigs, but I hate asking as the owner doesn't seem to like me at all.
