I encountered this forum via a reference from a well known audio forum, whose initials are AK. The thread in which I saw the URL was discussing audio software, which is of interest to me.
I've got a system that's a mix of two channel audio and home theatre, with a bit more emphasis on the two channel side of things, although it works fairly well for the time being for both.
I use an Oppo DV-980H as a CD/DVD player, a Parasound AVC-1800 for a pre/pro, a Yamaha MX-1 amplifier as well as a Yamaha DSP-A100 amp. I only use the DSP-A1000 as an amplifier as I pulled the jumpers sending the signals from the preamp side of the integrated amp to the amplifier. It works very well as a plain amplifier, and considering their cost, is a very good value indeed. The MX-1 is the main amp, though, feeding my Yamaha NS-1000M speakers. My center channel is a Klipsch SC-2 (IIRC) which I have bi-amped from the DSP-A1000, which has two center channels, so it works out well.
The low end is handled by a Velodyne HGS-10 sub, which integrates with the NS-1000Ms very well. I'd like to get an additional sub in the future, but it's not a high priority presently.
I'm only using three channels as it stands now for HT, but do have a pair of JBL L100s that I intend to use as rear speakers. They were my main speakers until I found the Yamahas, and have a custom crossover that helped them tremendously. The crossovers, in kit form, were a wee bit over two thirds of the cost of the JBLs, which were pretty much market value for the most part. I need to get some cables for the rear channels, which is the only thing holding me back. I know the JBLs will be overkill for rears, but they're not being used for anything as of now. I'll drive them with the DSP-A1000.
I'd replace the Klipsch center channel and the Parasound AVC-1800 if i were to make a change now. Actually, I'd like to add a tube preamp to handle the two channel side of things, and perhaps leave the Parasound. Dunno, that's somewhat up in the air for the time being. No hurry -- the setup works reasonably well as it stands.
I'm sure I'll be able to glean some knowledge from the denizens of this forum.
