I am adding a Sound Blaster ZxR sound card to my system with 5.1 analog outputs (not interested in the digital outputs because they are all lossy). Apparently, in the last few years 5.1 analog inputs have become very hard to find. I am thinking that I can feed the 5.1 analog outputs from the sound card to the Emotiva UPA-500 and then to a set of 5.1 surround speakers, with the sub-woofer having its own amplifier. Does that sound reasonable? This is for a single room, perhaps 400-500 sq ft, so the power output should be more than adequate.. I also considered the UPA-700, but I don't really need 7 channels and each channel has a lower power output.
I started by looking for something a bit better than the really low end 5.1 speakers that Logitech and Creative Labs offer, but everything I found was discontinued with the exception of Logitech's z906 which doesn't get very good reviews (LOUD, good for gaming, bad for music). I then looked at AVRs -- which are really a LOT of overkill for a sound system -- but, again, they are all very, very expensive or don't have 5.1 analog inputs (mostly both). Since all I really need is an amplifier to drive the speakers, the UPA-500 appear to be ideal. Mid-level in cost, good performance with no wasted features.
Forgive me if it has been posted before. I'm really interested in the UPA500. However, I'm not really sure they claim 80W all channel driven is honest. From the user manual it used a 350VA transformer, so it can't be 80W or 140W all channel driven. If 5 channels deliver 140W that require at least 700W power supply, even on a 100% efficient amp. Did I missing something?
Ever heard of storage capacitance? Also, the load on an amp is not constant, like that of a light bulb.
I'd rather not have to get a UPA-700 as I have no use for 7.1 on top of spending $100 more
I know to use the Pre-Outs but I'm unclear on what cables to use.
Thanks in advance.
Would a power conditioner make a difference? Or a power strip for the rack?
For suggestions for other manufacturers' products, post in the new thread (or search for one of the many comparison threads).
Personally, I'd ignore the buddy and put the money into a better AVR or speakers rather than into an external amp for your first HT system.
