Can a recommendation or experience with the type of amplifiers Nuforce or Jeff Rowland, of course, working with RM30 or some other model VMPS speakers. Any criticism, review or recommendation is welcome.

I can't speak for direct experience with the RM30s and the Jeff Rowlands, but as a NuFORCE dealer, and a VMPS dealer, I have often used the Reference 9 monoblocs with the 626, RM30, and RM40 models.

I also have many VMPS clients who like the VMPS/NuFORCE combination.

VMPS by design will allow one to hear gear differences much better than many speakers.  This means you can hear differences in electronics and even cables maybe a bit more clearly than some.

That said there are many fine sounding electronic brands to consider, and I think you'll find a pretty broad spectrum of users enjoying them.

If you go with NuFORCE, I can say that the newer V3 (version 3) boards and also the SE (special edition) models are nice improvements sonically.

I like tubes on ribbons.  I didn't care for ICE (switching) amps on them.  I say this only because I bi-amp and use ICE amps on the woofers.  ICE is great on woofers.  Even the big push pull tubes are not as good on woofers.  So you have to choose what you like.  For me, the mid range was too sterile with ICE amp.  Others like the clean (lean to me) sound.  You have to hear for yourself.

I have tried several amplifiers with my RM-30M and I came to the same conclusion as Woodsyi. The mid-range neo-panels and the ribbon tweeter mate best with tube amps.  I strongly recommend a tube amp if you are going full-range with a single amp.  If you're biamping, I'd suggest tubes for the mids and tweeter and ss or ICE for the woofers. 

If you have a chance to try a tube and a ss amp, I think you'll hear what we're talking about.

X3! Tubes on the panels.

I use an EAR 534 which is a 50WPC EL34 based tube amp on the whole speaker, bi wired. Excellent, IMO and I do believe there is a magic with tubes on the RM30, 40, 50, etc. I have not really felt the need to bi amp my RM30's as I a getting very good bass with just the one amp.

Alex,

I'll have to invite you over to hear my bi-amped RM30s.  Removing that big low pass inductor coil on the woofers and replacing it with an electronic crossover really uncorks the speaker.  Bi-amping also allows judicious room correction EQ on the woofers without mucking up the midpanels and tweeter.

MiniDSP module + Woofer Amp + a little XO surgery takes this speaker to a whole 'nuther level.

Hey Russ,

Alex actually has the RM30C, but if you have a GTG, you have to try some of his Wiring/Cables on your system too.

I'd love to hear your RM 30's...let me know.

My friend Roko is the owner of the model RM2, which is connected to the Vector P6-preamp/A6 bass amplifier (solid state) and the tube  to the panel. He plays it quite well, though for my taste a little too soft in the middle and high. But it's a matter of personal taste, taste is not about debate. Regardless of musical genre like blows from bottom to top, of course it includes the performance and speed. At this point its RM30 listen via Marantz PM15S2 whose declared power 2x90 watts / 8 ohms. I know someone that this sounds strange, little integrated amplifier on a large speaker. I am aware that it can not be expected from the extreme control-attack and so muscular. However, I am interested in how the panel works with it, and what is the speed of performance. I assume that mono-blocks of the Marantz might be an ideal solution, but somehow I was quite huge box amps, so think about efficient amplifiers, even if it were in the style of performance NuForce, Jeff Rowland, or something similar.

[Russtafarian]

Darac,

The RM30 is a very transparent, revealing speaker.  The better the amp, the better the speaker will sound.  If the amp is not smooth and delicate in the mids and highs, the RM30s will deliver the unpleasant news to you. 

That said, I've heard good things about the latest Marantz amps and I'll bet the one you mentioned will work well with the RM30.

Here's a review written by my friend Frank about that Marantz amp and matching SACD player.  You might find this interesting.

Let's talk on Sunday at the LAOCAS meeting.

Sounds good...see you Sunday.

I have the RM30M speakers and use one Son of Ampzilla SS amp. It is said to have tube characteristics and was well thought of in this combination.

Hi Hipper,

No doubt, one of the more perfect matches depending on your listening preferences, but Darac might not easily find one in Croatia.

In the last ten days I had the chance to try the Marantz PM15S2. The sound is slightly soft, but it is by no means laid back as it can read the reviews. It has its charm, especially if you are listening to Bossa Nova-Latin Jazz, while the classics still missing that final attack. The reason I see a lesser effect, although it is rated at 90 watts per channel. However RM30 with  four Kicks by 16cm and 25cm woofer need more power than the average integrated amplifier provides. I think some would-Amping combination provides optimal results, listen to my Marantz has expanded the horizons, and added it to a narrower selection of amplifiers. Who knows, maybe Marantz combination with another brand of awakening something like a winning combination ...
