Been awhile, thought I'd update the thread (for posterity, if nothing else).
I did in fact get the Ars Sonum integrated. Loved it. Used it for 2 years with my beloved VSM-MME speakers. The combo was fantastic.
Over the course of our relationship (ahem), two shortcomings came to mind.
One, I didn't get a tape loop on it (got it used). This was a mistake. If you want to get an Ars Sonum, get one with the optional tape loop. Honestly I have no idea why this is an option -- it should be standard. Why? Well, the BAM module (which may well be the bane of my musical existence) needs to go somewhere and quite frankly, putting it between your sources and your integrated's inputs is a bit limiting -- unless you plan to buy a BAM with multiple inputs and a switch, or buy multiple BAMs and have one per source.
An aside -- I went the multi-input BAM route. It's a PITA and I'm still not sure that the selector circuit on the BAM is anywhere near the quality of the one in the Fila, so I was always thinking that the BAM implemented and used this way was the Least Valuable Player on this particular team. And without a tape loop, the options for comparison simply don't exist.
Two, the VSM-MME + Ars Sonum can put out very prodigious volumes, and in the room I had it in (too small, really), I managed to get some startlingly deep bass. When I switched rooms, to a much (MUCH) larger open basement, I suddenly found that the bass, while very tuneful, true, and altogether wonderful, might not benefit from a bit of a kick in the nether(world) regions. So, an experiment in adding a pair of subs became an exercise in frustration. The line out on the Fila is a fixed-volume (rec out), so that couldn't be used. Using the speaker-level inputs on my subs was an option, but those Cardas binding posts made fitting multiple sets of spades just about impossible. But whatever I chose to do, there was still the non-bypassable BAM, which was rolling off all very-low-freq info oblivion. [Sigh].
Well, at least WRT to the subwoofers, I'm told one can get a standalone Velodyne SMS-1 to add/correct that BAM-induced roll off for your subs ... assuming you have a variable volume line out. Which the Fila doesn't.
Ok, so that said -- and all my deep-bass/large-room challenges aside, did I mention that the Fila sounded wonderful? It did. Is it perfect? Almost!
I sold my Merlin VSM-MME's last summer, and the Fila at about the same time. Why? Time to upgrade! Late last year, I was lucky enough to take delivery of a full set of Joule-Electra gear and a spanky new pair of VSM-MXRs. But that's another post. ;-)
