Best amp for Dunlavy V

I am a tube kind of guy, my wife is a tube kind of gal and we own SC-V's. My wife and I primarily listen to large scale late romantic music, art techno, and organ music. We love the Dunlavy's. But to get the most out of them you need a big room, big power and room treatment. We use the Sigtech DSP combined with a very simple ASC configuration. Measured, in my room, with the SigTech, they are virtually flat down to 22HZ. The room is about 7000cu ft. The amp selection goal was clean 108db peaks. In the room that measures out, allowing for Sigtech correction at about 400 watts. Given the impedance curve of the Dunlavys, if you drive them from a 4 tap on a tube amp you will need additional power for solid bass though this isn't an issue with most SS. The listening tests follow the measurements. In the last year we have driven them with Bryston 7BST, Spectral DMA 150, DMA 360, ARC VT-200, ARC Ref 600, monoblocks, CJ Premier 8 Monoblocks. VTL MB-750, Melos Soloists 400 watt triode monoblocks. On the Rite of Spring, and other large scale works, the lower power amps, including the CJ's choked. The Spectral monoblocks were too harsh. The Bryston was OK but too SS sounding and not in the same league as the other choices. I originally was going to biamp with SS on the large woofers and Tubes above. But while the bass on the SS units was excellent, the high powered tube monblocks was very close so we didn't bother. The choice between ARC, VTL and the Melos for us was a matter of subtle taste in tube sound. We like the slightly darker sound so we went with a custom version of the Melos Solists built last February between bankruptcies. They were specifically built to match my pair of Dunlavys based on the impeadance curves. That Melos amp also has a huge joule capacity power supply so peak power is no problem (measured as well as listened to). We've owned a lot of ARC stuff over the years and would probably have gone with them if the Melos opportunity hadn't come along but the difference to the VTL was a matter of taste. Bottom Line: 400 watts plus of pure musical power that suits your taste.

Great Input Plsl. Did you have the Melos custom built? I am getting excellent sound with the Wolcott Amps but still have an urge to audition another amp. What changes did they make from the original Melos?

Which sounded better on the V's the ARC VT 200 or the ARC 600?

The Melos was custom built on the output to match the impedance of the Dunlavy's. Also this unit was their new design including a revised power supply that gave it a Joule capacity equal to the ARC 600. These are both critical for solid bass and peak performance into the Dunlavy's. I don't think Melos was successful in their corporate reorganization this year so I think they are now out of business. The point of my original post here is to stress the need for LOTS of power to bring out the best with the SC-V's in a large room. Between the two ARC units I actually preferred the sound of the ARC VT-200 but as I said I prefer a warm sound. This is from having front row balcony seats for the Chicago Symphony for many years. The RCA classic recordings from the 50's were miked with that mid hall perspective and accurately captures the sound of the CSO. However, even before the Sigtech correction the peak capabilities of the VT-200 were pushed to the limit as measured and listened to. With Sigtech correction, there are places in the bass spectrum that required an 8db boost. This range of frequencies corresponds to the bass drum, so for Mahler or Stravinsky the amp demands are pretty outrageous when you then add a full brass choir in the midrange. I have measured the CSO at 112 db peaks live in that music! With the Sigtech, measured in room impulse and frequency response is superb. The musicality of these speakers is truely amazing. When we started listening last year we had budgeted a lot more for speakers and amps but for our tastes the Dunlavy SC-V's with the Melos gave us what we want. French Organ music is awesome. With the Melos out of business I would seriously consider a big VTL in Triode mode. I've not heard the Wolcott amps, but I would first like to know if they would be able to push 500-600 watt peaks into the Dunlavys.

I drive them with Classe CA-400.using Classe CP-45 pre-amp, STRAIGHT WIRE SERENADE bal INTERCONNECT BETWEEN PRE-AMP AND AMP A MUST FOR LIFE LIKE UNRESTRAINED SOUND. All that in a average size room.
