Joule vzn 80 or 100 for merlins?

I agree the VZN 80 is more than enough power with the VSM in most instances. The 100's may be preferable in a larger room but you don't give room dimensions. I had a VZN 80 in my 16X18/12X8 L shaped room with 10' ceilings, no problem at all. Dynamics may open up a bit more with the 100 monos but they will also introduce more heat output from 12 rather than 8 output tubes which is worth some consideration if living in a warm climate. These amps DO warm up a room.

The Joule is lovely with the Merlins, you couldn't want for more, especially with massed vocals and opera, the best I've heard the VSM for this type of music.

Just a note regarding power for the VSM. I'm going to be running my VSM-MMs (wich should arrive in the next couple of weeks) with 16 SET watts. After speaking with knowledgeable individuals with experience running the VSM with lower watts, I'm confident that they will sound great. The only issue being ultimate SPLs with the lower watts. This should not be a problem since generally I do not listen louder than 85db peaks and do most of my listening in the 75-80db range.

Hopefully I will be very happy with the results. I will report my findings when I get the speakers. I've seen many post that suggest you need 60,70, 80 or more watts for the VSM. I do not believe that is true. I'll find out in a couple of weeks.:-)

So, for people who are using lower watt amps and are considering the VSM, check them out. Give Merlin a call and talk to Bobby. He'll let you know if his speakers will work with your amplification. Happy listening.

Cheers

I have 30 watt Dehavilland monos driving my Merlin VSM MM speakers and am more than happy. Plays much louder than I care to listen to. Even without cranking it up my wife is always screaming at me to turn it down.

Do those Dehavilland monos use OTL tubes like Stargates or VZN80?

They use a large and strange SET tube, the name of which I can't think of. They are SETs, not P/P or OTLs.
