Best amp for Raidho Speakers


I just bought a pair of Raidho C1.1 speakers. For you Raidho experts out there, what do you feel is the best amp for these speakers? I will be using an Audio Research SP20 preamp. I am currently using Mcintosh MC275 amps but I think the Raidho might be better with a solid state amp. What is the consensus on this ? Is Raidho better with SS or tubes ?

Much appreciation for reviving a thread that needed revival IMO. I must not have noticed the comment referring to Raidhos as " not really known for dynamics". A rather remarkable statement, since I have to wonder how a Raidho could be setup so badly that dynamics weren’t immediately apparent given a dynamic music selection that one is familiar with.

With different amp choices, my C1.1s sounded vastly different wrt dynamics. They are *meant* to be driven with an enormous current reserve, and as such may not be appropriate for many rooms and/or ears.

I’ve written several times (at least twice to Raidho themselves) that the published impedance plots are not what I observed and nothing close to what I’ve measured myself. These speakers are meant to wind up and blast out power in the mid-bass and very low mids. NOT the polite phase angle many might be expecting.

It’s a strange point to make, but I’ll make it here anyhow: I also drove the C1.1s for awhile with MX-Rs - the mid-bass was TOO impactful for me (or rather my room which I feel needs almost no more modification). So I tried lower powered tube amps instead and ended up enjoying the C1.1s more. Yes ... clearly I there was some soft clipping there but I didn’t notice it - the dynamics were still incredible at lower volumes.




Glad you found an amp that suits your tastes. So far, nothing has won over my heart (ears) with my D2 like the Hegel H30, though the Gryphon has always interested me...
count me jealous of every one of you who didn't do what I did: sell my Raidhos:-(

Hegel, Gryphon, MX-Rs ... when I think about the difference between what you're hearing and what I've had before and after my C1.1s ...

the main difference by far is the dynamics. Even though I'd say the hallmark of Raidho speakers is the outstanding ability to blend drivers over the x-over range, it's the dynamic "intention" that really set my C1.1s apart from anything else I've owned. 
Now that Raidho is owned by GamuT I would guess that any new speakers will be voiced with their own amps.  I would try demoing with the GamuT Di150 integrated or D200i stereo amps.  IMO the Di150LE is the best SS amp I ever heard.
