High powered amps for low sensitivity


I have a pair of speakers that are 3 way with raal ribbon tweeters

Several amps I have do not like the 84 db sensitivity or 4 own load at higher volumes and with dynamics

The speakers sound fabulous when not pushing the amps limits

I am running out of usuable volume in my system due to a .24 mv mc cartridge and the high demands

Looking for something very dynamic and natural sounding that can handle a hard load to drive these

McCormack DNA 250, 500 or the 750 Mono's. I also like the Coda and Threshold amps. You can also easily find the Belles 350a that would be similar to the previously mentioned amps.

Personally, I use a Rowland M112 with my Evolution Acoustics MMMicoOnes that are 86db and 4 Ohm minimum.

Good Luck in your search!
This is a perverse quest.

High sensitivity/low power is the goods - do you have a friend who can let you hear such a rig - you may never go back...
Triode, I get where you're coming from... but not everyone needs to take the same path to musical audio bliss.

I feel both approaches can be valid so I'm not taking sides. Although you have a different preference, why discourage others from choosing another way?
Since you used "natural", have to answer Plinius. Dynamics without the dramatics.
Audiotomb-

You didn't say if you were looking for a tube or an SS amp.
It took me more than a few auditions and a while to find what I was looking for to drive my low sensitivity Totem Mani-2's (85db, 4 ohm), but eventually found contentment with, first, a Cary CAD-120S Mkii, and finally with a move to a pair of Rogue M-180 Monoblocks. Happy hunting.
