Adding a Rotel RMB-1075


I have a Rotel RSX-1057 5.1 Surround Sound A-V Receiver used primarily for music and less for HT. I now have a Marantz SACD player and am absolutely loving this new format in multi-channel 5.1. Fabulous. Am building my collection of SACDs now. The RSX-1057 is conservatively rated at 75 watts/ch x 5 in to 8 ohms at 20hz-20khz all channels driven. My two main speakes are the B&W DM603-S3 with the full complement of B&W center channel, surrounds, and two powered sub-woofers. Sound is out of this world. I'm thinking of my next upgrade and am considering adding the Rotel RMB-1075 multi-channel 5.1 amp at 120 watts/ch in to 8 ohms all channels driven and use the RSX-1057 just as a surround sound processor. What would I get out of this addition? Would I get more out of my mains and center channel because they're now being driven by more raw power? Would I realize more of the potential out of my B&W speakers? WOuld I really hear a considerable difference going from 75 watts/ch to 120? More slam and punch, more detail, more information, greater soundstage? Thanks all.

Hi Pdn

If you want to stick with Rotel, I recommend the RMB 1095 (200w x 5)as you would need that much power increase over your 75w x 5 to make a real difference. Your speakers will handle 200w so long as you do not play at rediculously high volume.

An altrernative would be to upgrade by going to a seperate proecessor/amp set up. Like the RSP 1068 pre/pro or, if you need HDMI, the 1069. Couple that w/ an RMB 1075 (120w x 5). I used to drive my surrounds with the 1075 and found it to be a great amp.

Thanks for the advice. You are in agreement with Mekong56 so that would be the way to go. I guess going up to 125 watts x 5 from 75 x 5 will not produce a noticeable difference. That's what I needed to know and why I started this thread. Thanks guys.

Mmarvin19:

You mentioned if "I want to stick Rotel....." Are you suggesting another brand? What other suggestions would you have and why? I would love to hear back from you. Appreciate it.
I think at its price point Rotel is hard to beat. If you want to move up what is your budget?

If you can afford it, I recommend seperate boxes: a pre/pro and a matching 5 or 7 channel amp. But,there a number of avr receivers that outperform Rotel. These are in the $2000 to $5000 price range.

Also, do you need HDMI input (for DVD, Blu Ray Disc, HDTV)?
how about using your current unit as a pre-amp and adding a large 5 channel amp / mono blocks ?

you can never have too much clean power on hand - it adds a certain amount of ease and authority to the music. what blows a speaker driver is when it receives a 'clipped signal' from a amp (amp does not have the current to produce the signal cleanly)

btw, b&w's match beautifully with classe amp's.
I have zero interest in HDMI and video circuitry from an AVR. This is all to do with audio sound. I have an HDMI DVD player connected directly to my Sony Bravia LCD TV and that's more than adequate.

My budget would be around $1500.00 for this next step. Can you name the AVR's that outperform Rotel at the $2K point? I need those recommendations and why. I love the features of the RSX-1057 such as separate volume controls for the center channel speaker and the subwoofers. I use those features reguarly from the remote. I love that the Rotel defaults back to a preset volume level each time you turn it on. This way there's no surprises if you know what I mean. It also has many surround sound "music" format choices, more than I've seen on other units such as Marantz. Marantz AVR's in my opinion are definetly more geared to HT than music. It decodes HDCDs into two channel which I have a number of that I play and sounds fantastic. It has multi-channel input for my newest SACD player.

I've always just wondered if Rotel power is still a bit too polite compared to others. For example, what about a comparable NAD AVR or separates? Would that have more oomph, slam, & punch than Rotel? How would you compare the two in terms of pure audio? That was my experience back in the 1980s and early 90s before AvRs (2 channel receivers) and I guess it's still stuck in my head.

Mono blocks I just don't know enough about and I really don't have the physical room for them anyway but thanks for the suggestion. Yes CLASSE amps are super but probably out of my budget. Again, $1500.00 to $2K.
