I use a separate amp to power my mains and center. I have my speakers (NHT 2.5i) bi-amped. Using a Parasound HCA855A (85watts 5ch). I am currently using a old Kenwood 8070 ProLogic receiver. I hope to be going digital by the coming summer.
I got my amplifier from Frank Carter. Hi ya Frank, the amp is working great, sounds wonderful.
I must say, I really like Bi-Amping my front main speakers. I would strongly recommend that you try this if your especially if your speakers are inefficient, like my NHTs.
Phil O, I also have the Parasound HCA-855A and NHT 2.5i. Currently I am using the pre-outs of my Pioneer VSX-35TX to run (a single channel of amplification to each speaker) to my 2.5i's, my AC-1, and 1.5's. It is a nice surround setup. But maybe I should try to bi-amp the 2.5i's for giggles. Could you describe what kind of bi-amp you are doing (passive or active) and what kind of connections you have made to accomplish this. Thanks, Curtis
Use preouts here as well.... Yam DSP A1 ( their flagship a few years ago).... to nOrh Le Amps monoblocks.
Not even close (which is not to say the DSP A1's amp section are not capable), as the nOrh amps are overbuilt and simply clean the Yam's clock.
Keep in mind that the DSP A1's amp section are truthfully rated at 110W per channel; and were even tested by an independent source as consistently delivering 125W per channel. Conversely, The nOhr Le Amps are listed at 100W per channel on their website. However, John Curl tested them at 75W on his test equipment, after much hoopla in an AA thread (a bloody kicking match), I should add.
Bottom line, the nOrh Le Amps outperformed the DSP A1 in spades. And kicked the Marantz MA 6100 monoblocks (125W THX Ultra certified) with no questions asked. All amps are the same.... right.....
Steven, Chris, I passively bi-amp my speakers. I didn't really notice much difference in the high end, but the mid range did improve some, and the bass was better. I wouldn't say that it was an earth shattering experience. However I don't want to go back to the (not so any more) normal way.
Now I need a two ch. amp for the rears (NHT 1.5). But that will have to wait a while. :frowning:
I am currently using a Pioneer Elite VSX-39TX as a pre/pro. I use a Parasound HCA-1205A to power the 5 main channels, and an AMC 2100 stereo amp to power the two rear center channel surrounds ( 7.1 ). I absolutely agree that pre outs on a receiver are a must, and that in most cases the amp section in receivers can not keep up with a decent seperate amplifier ( especially with all channels being driven ).
I think pre-outs is a necessity for anyone posting the question. If you are here, it's because the "bug" just bite you...
I started with a Yamaha HTR-5150 for 6 months. Then RX-V2200 for 2 months, then RX-V3200 for around 6 months. Then the "separate" bug bite me. Add a Rotel RMB-1095 (5X200W). 1 month connected on pre-outs of the RX-V3200. Then sold the 3200, now using a Rotel RSP-1066... Thinking of the Anthem AVM20v2 now...
If you are taking the time to post here, it's because you are really interested in HT. So pre-outs are a must for you.
For my father-in-law...different answer, because will probably will never use those... He will use those ONLY if he ask me to help him upgrade
Another for pre-outs, "just in case"...
