I own a Momentum Stereo s250 and would never trade for a tube amp. Tons of power with uber finesse and musicality. A modern work of art as well. I personally like my speakers to much to worry about a 'lightbulb' popping at high volume. Just my paranoia I suppose but when ARC described tubes as like light bulbs concerning failure that was it for me when ss is so very good now.
Arc Ref 75se vs D'Agostino Momentum Stereo
I have the opportunity to upgrade (?) to a D'Agostino Momentum Stereo for a good price. I was previously using a bought new Ref 75 se which blew 2 tubes at the 30 hour mark. Despite being biased every 2 weeks. However, not only did the tubes blow ( due to the deterioration of the of the cathode coating of 2 tubes, I was told ) and the biasing resistor, it took a big chunk of the gold trace on the pcb and shortened the transformers as well. This caused quite a stir between me, my dealer and Arc which took several months to resolve as I'm not based in the US. In the meantime, I was using a loaner ref 110 to tide me over. To make a long story short, just as my replacement 75 se (new ) arrives, I get an offer from my friend on the Momentums. I have been traumatized by this experience so I was thinking of staying away from Arc power amps ( I've read some posts on similar problems ) hence willing to the try the Momentums.
I am basically a tube guy so an SS amp even though the Momentums are suppose to be warm they don't have that tube bloom which I can't seem to live without. I've been doing an A/B the last few days between the Ref 110(I know is' not the same without the kt 150's and all ) and the Momentum cause in case I get the Momentum's I can sell the Ref 75 SE sealed in the box as in "new". I can seem to decide as both have their strengths and weaknesses. The rest of my system consists of
Ref 6 pre
Von Shweikert Audio Vr 44 Aktivs
Estoteric K07 sacd/cd player
VPI Prime with ADS and Benz Micro LPS-MR
IC's are all MIT - oracle and shotguns
PC's are all Shunyata alpha series.
Speaker Cables MIT Matrix 28
Room size 35 sq.m.
Points I am considering, synergy among the same manufacturer's, the Vr 44's are active so I don't really need a lot of power just enough for the tweeter and midrange. But those Momentums look gorgeous and the deal is quite good. From my recent A/B tests, IMHO I noticed that the ARC does better with vinyl while the Momentums does better on Cd and streaming from my macbook to the esoteric. Help me decide, your inputs are welcome. This offer expires in a few days so I have to decide quick. Thanx.
