Has Anyone Uesed A PrimaLuna Amp With Harbeth Speaker's

I would suggest emailing Gig Harbor Audio as I am pretty sure they sell both brands and know they would happily give you the benefit of their experience no matter where you live. The owner is honest and always happy to help.

Just look at these Stereophile measurements: https://www.stereophile.com/content/primaluna-dialogue-premium-power-amplifier-measurements it has a pretty bad load dependent frequency response.

For those who don't read the article, the response is on a simulated speaker load.

Transformers are designed to match an impedance. When they don't, frequency response curves like the those shown are the result. ALL transformer output amps will deliver a similar curve. If one were to log the current rather than the voltage on a solid state amp, a similar non-flat curve would result.

If one runs a room response graph with a tube amp and a solid state amp on the same speakers, they will overlay indicating the power to the speaker is the same.

I have a PL Prologue 5 driving 85db/W 3.6-12Ω speakers on the 8Ω tap. On some material it is scarily good. Bass is tight and detailed. It plays as loud as 100wpc solid state which is only 4db more power than the PL 36wpc. I can get 100db peaks on wide dynamic range orchestra material. My room is 16 * 33 and I sit 14' from the speakers. A tube amp cam be pushed farther than solid state, which get ugly FAST!

One visitor said "Your system is so precise." when I played him the PL.

Internally, the PL amps are gorgeous. No PCB / tube socket connection to fracture. It is my 5th tube amp dating back to Citation II, 2 x ARC and 1 custom KT-88 monster.

I've never heard a solid state amp ever come close to the sound stage presentation of a good tube amp. Sure they're colored, but so is every thing!

If you can afford it, dual mono are always the way to go.

Definitely get a refundable demo.

DISCLAIMER: I also appreciate a good solid state amp.

The Croft Phono is a GREAT little integrated! very musical.

Get a dual mono, hybrid ss class A amp. 
By far the best sound reproduction available. Don’t care if it’s chinese, Japanese or American. They all use top notch parts and weigh a ton. I’ve heard a Cayin compared to a luxman and would take either. Class A baby with those Harbeths. 

Hey for any of you guys that question PrimaLuna in the Seattle area I invite you to come to my home and listen to them make my Magnepan 20.7’s sing. Again a speaker that is deemed a power hog and at 87db has never sounded so go in my listen room. No bullshit I get chills when I’m listening to music and a lot of that is due to PL and it’s amazing build and sound quality.

Cheers
