Raven Osprey with Spatial M3 Sapphires

@jjss49 
thanks so much for the info, Just curious as to which of your three amps you prefer? The fact that you also have the M3's is extremely helpful.
I am also looking at the LTA line and that would compare with the Raven Reflection in pricing. I'm new to this tube stuff never owning anything other than my grandmothers tube radio, lol. I do however have a Modwright Pioneer LX500 player which I love. I have wanted to experience the tube sound through these speakers and have an email out to Clayton. I appreciate your insight.

I had a Decware Torii II (25 watts/channel) and it wouldn't sufficiently drive Spatial Audio X3s. At least in my room to the levels that I like.

That said, your room is smaller and you listen at lower levels. And I would bet that Raven is using better transformers than Decware (maybe, maybe not). So you would more than likely be fine with the Osprey.

i like all three and at this time can’t pick a favorite

the audio mirrors... being SET has most bloom and classic tubey ’roundness’ and ’meati-ness’ - lovely sweet single ended sound but with plenty of power to grip the woofers and get loud with ease and no slurring

zotl 40 is least tubey sounding -- being output transformerless it plays closest to tip top solid state... pure extended crystalline highs, very specific imaging, fast, visceral bass -- with old stock mullards (or japanese equivalents), it still gives a nice degree of luscious tubey fleshed-out lower treble and midrange that SS can never do

arc ref 75 is kinda in the middle... some more warmth than zotl, not quite as sweet as vlad’s SETs but better deep bass -- due to the greatest power reserve, there is just an effortless quality to the sound that is captivating and it has the biggest broadest deepest image - note this amp is balanced in only, so makes more demands of upstream gear

so i alternate, listen intently, still trying to figure out how i would rank them

if you are new to tubes, i would suggest:
-- very important, make sure your m3s’s are FULLY broken before you audition $$$ amps... mine were still smoothing out towards their settled in character 1000 hrs in from new
-- i would give the raven 30 wpc a shot. given money back trial offer .. my guess is that it would fall between the audio mirror and the arc ref amps -- and that to me is roughly where the tonality a ’typical’ good sounding tube amp would fall in the ’skim milk to full fat’ spectrum -- and so it is a good place for you to start and hear what good tube amplfication will do w the spatials

@jjss49 Thanks for the input. I did contact Clayton about the Osprey and his response was ..."Yes, this amp is excellent and should have a good grip on the M3s. Good choice."
That's a pretty good endorsement so I may just move towards a trial of the amp. I am also very interested in the ZOTL40. My only source that offers balanced outs is my DAC RME-ADI-2 but also offers unbalanced as well. other sources Modwright Pioneer LX500 and SPL-Phonos have unbalanced RCA's. It's a lot of money for me so I'm weighing out the cost to pleasure ratio ;-) I do appreciate everyone's input

audiosaurusrex so after a few months, what do you think of the sapphires ? I listen to similar music as you do "jazz, blues, R&B, Classical"
