RMB1075 x 2 with PSB Platinum speakers

[Maxfli]

I am in the process of selecting components and speakers for a new HT. I haven't selected a 7.1 processor yet, but am thinking of the following setup:

Room - 19' x 15' x 8.5' (converted 2-car garage well sound insulated)
(2) RMB1075 total 10 channels 200W per into 4 ohms
(4) bi-amped to FR and FL
(2) bi-amped to Center
(2) single to side surrounds
(2) single to back surrounds

Speakers - PSB Platinum - 4 ohm 7.1 system

Does this setup make sense? Has anyone paired Rotels with PSB speakers? Platium series?

Thanks in advance for any advice or comments.

The 1075 is 120 wpc, not 200. You'll need the 1095 for that, which runs twice the cost of the 1075. I'm personally not a fan of the 1077 amp, but it may serve your purposes better here, and almost everyone else thinks it's a great amp. You should give it a listen. May even find you can skip bi-amping.

he is going into 4ohm not 8. Its not quite 200 but I think its close.

Thanks for clarifying the 4 ohms. I'd like to use the 1080 in place of one of the 1075s, but from all the literature I've seen, it doesn't appear that it will run at 4 ohms. Is that correct?

The 1080 should run at 4 ohms just fine And PSB speakers are quite nice, should sound lovely with the Rotel gear :T

[Maxfli]

Thanks for your response. Would you recommend bi-amping with the 1075 as described or using the 1080 for the Fronts and the 1075 for center and both sets of surrounds?

[aud19]

I'm not a big fan of biamping because most people don't crossover the signal prior to the amps and disable the crossover in the speakers which is the proper way to do it. In that case I'd go with the 1080/1075 as I'll think you'll get better performance/dollar as well as better stereo performance from the 1080. If you are planning on biamping properly, as I mentioned above, then two 1075's could be quite nice as well but it's a lot more work and more cost in crossovers and cables.

Ditto to the above post.

As for watts/ch, 100 at 8 ohms is equivalent to 200 watts/ch at 4 ohms. If the amp does not double exactly from 8 ohms to 4 ohms, you're probably losing something (most likely headroom).

I'm a bigger fan of the 1080/1075 idea. Again, you may want to look into the 1077.

looks like it does do 200x5 into 4ohm

I'm using a 1075 to power a set of PSB Stratus Silver i's in my 7.1 setup.
They sound lovely using this amp.

Rotel and PSB - I'm not alone?!

I've got the newer PSB Image towers and center powered by a RSX-1067 and backed by a new REL R series sub.

No complaints.

Looking at a pair of M2s and a C something (PSB) -- what models do you have?
