Minimum Power Needed to Drive Klipsch Cornwall IVs? - Considering Erhard_Audio Ray


I'm new to the the hifi world but have taken up the hobby with alacrity. I recently purchased a pair of Cornwall IVs to go with my Rogue Audio Cronus Magnum 2. At the time I purchased the speakers I had no idea what speaker sensitivity is. Now that I do, I realize that I have a lot of interesting options when choosing an amp. I have been toying with the idea of getting an Erhard-Audio Single-Ended Ray along with their Aretha pre-amp. The amp is only 4W/channel. I'm highly skeptical but I've been told that 4W is plenty to drive a 102db speaker and that the sound of an SE amp is amazing.

Wondering if anyone has experience driving Klipsch Cornwall IVs (or other high sensitivity speakers) with a low wattage amp. I'm also interested in experience with SE amps.

My system consists of the following:

Technics 1200G
VAS Nova cartridge
Rogue Audio Triton 2 phono pre-amp
Bluesound Node
Musican Pegasus DAC
Rogue Audio Cronus Magnum 2

My room is 15' x 30' with 14' ceilings. It's a photo studio in an old mill. I'm often moving around so I need the sound to fill the space. BUT I've gotten noise complaints from my neighbors so...

Musical preference is all over the place. Today I'm listening to Dire Straits, Sturgill Simpson, Paul Simon, Miles Davis, Tycho, Post Malone, Taylor Swift, Michelle Gurevich etc.


I would go with a tube amp. The heritage line loves tubes. Or a class A amp.

For example, I have an ARC75se, 75W/ch, with klipsch forteIII, and at roughly 5-6 watts, it is plenty loud and sweet.

I have a lot of seat time w buddy Cornwall i restored / updated. He uses a 300 B Toolshed integrated ….. sounds lovely. When i was working on them a MC240 really made them sing….

Is there something you don’t like with the Magnum combo? Just asking because it’s on my list for the same speakers. Always heard that the Cronus Magnum had some warmth. It had some balls as well. Kinda what I’m lookin for. 

i heard the ones I bought at the seller with an Ayon I think Triton 3 . It was real good. Different room etc but Ayon is on my list as well.
