Be aware Vidar has no concessions for HT - no relay switching, auto sensing or remote turn on. You'll still need the remote control power strip. And you might find 100 wpc a little ...enthusiastic... for near field listening. It's designed more for running speakers on the other side of a medium to large room.
[edit] Ah. I see the UPA-2 is rated for 125 w so you'll be used to overkill.
The power on can be handled by one of those smart triggering power strips, where I can plug the receiver into the sense outlet and the power amp into one of the switched outlets. When the sense outlet increases in power draw, the switched outlets turn on, and vice versa, so this isn't a huge problem. As long as - that is - the Vidar doesn't do something silly like enter a standby mode when it first receives power, in which case that option is out.
I actually bought the UPA-2 for my RBH sx-6300 towers I'm going to use for my home theater system. They are 4 ohm speakers and the manufacturer recommends 100-300W to drive them. I was worried my Deon AVR-x1300W might not be up to the task and wanted to supplement it on the two main channels.
Problem is my Denon doesn't have pre-amp outputs on the main channels. (what I thought were pre-amp outs for the mains on the back were actually pre-amp outs for a zone 2, which doesn't help me much
So, now I'm either going to have to buy a different receiver with pre-amp outs (I've only had this one for a couple of months, so that feels very wasteful) or just use the interrnal amp in the receiver to drive the sx-6300's. The manual claims it can handle 4 ohm speakers on all channels, but there is no spec for its output into 4ohms. It is rated at 80w intro 8 ohms. I'm just hoping it is powerful enough to not clip at normal listening levels, and doesn't have too terrible of a THD at 4 ohm.
Well, I've also read about these resistor devices that claim to take a high-level output and convert it to line level, but I can't find much in the way of serious testimonials for them, and they seem a bit like a risky hack... (though if anyone knows anything about these, I'd certainly appreciate input)
So anyway, yeah, that's why the UPA-2 is at my desktop serving overkill duty.
