Among ARC preamps I have only ever heard the LS9 and, of course, have yet to hear the Pass 150.5. Further, I've never heard my current amp, (the CDA SDS), with anything else than a passive preamp, so it's hard for me to compare. But at this point I'll say that the LS9 seems very transparent and very dynamic. Also bass seems tighter and highs maybe just a little brighter. These latter characteristics might be explained entirely in terms of the LS9 being active rather than passive.
Hi Feanor.

The ARC seems to be more lively in presentation. Nothing boring about ARC. The Pass is more neutral and can be said to be on the warm side of things. The contrast in Both brands are dynamic....but the contrast in the two different sound temperatures( warm...lively)may make for a great synergy between the two.
