Danger Will Robinson, Danger! I tried a Lyngdorf TDAi2200 in bygone years and despite knowing I'd have to be extremely careful with volume settings across both it and the DSP5500s, a moment's lapse in concentration between remotes meant that a full volume white noise calibration signal was sent to the DSPs, which were also on full volume. The deafening hiss lasted for a few seconds before the tweeter output wilted markedly, to terminal effect. That gaffe cost me a new pair of tweeters from M. So I say proceed with caution...

Cheers
George
