ARC D115 Mk2 vs ARC M300


Currently running two D115 Mk2s (passive bi-amping with ARC SP10 Mk2 pre). Am considering replacing the 115s with M300s. Having reliability problems with the 115s. Am I jumping out of the frying pan into the fire? The M300s are hybrids. Tried the SP11 (hybrid) and returned to the 10. Same with ARC hybrid tube amps? Comments and advice welcome. TIA

I have had much experience with ARC amps and also own and SP10, I know many have raved about the D115 but I never developed a liking for it. So think about this as you consider my recommendations. My favorite ARC amp was an unmodified D75A. It had an awesome sound until I "ruined" it with a cap and resistor upgrade in my "upgrade components for better sound" period in my life. I have since abandoned that philosophy. For the D75A, you also need a warehouse full of 6CG7 tubes if my memory serves me right. I think it used 16 of them. I have heard the VT100 series but while it sounded good, I felt there were better in line with my preferences(my opinions, no flames please) My experience with the SP11 is same as yours, owned it and sold it for the 10. With the right tubes, I have not found better. With so much gray hair on my head and lots of experience (I find music to be one of the main stress relievers on a day to day basis), I would suggest some amps you might consider. I cant comment on the BAT as the previous poster suggested because I have no experience with them. Here are two combinations for your consideration and are based on hooking them up with SP10 and combos of many speakers.
Cary SLM-200. Awesome, awesome tube amp and goes great with the SP10. There is a special synergy there.
Plinuis SA250 as solid state with one exception. If you use a very low output moving coil cartridge in an analog situation, the synergy is not there with the SP10. I find plenty of gain but not the magic. I dont know why this is so, but this is my experience. With medium or high output cartridge it sings. To me, this is the best solid state amp I have ever heard and owned (again, I am sure there is always better but not for me. These two amps caused me to stop dying under the ongoing upgrade disease). Cant say will never look or buy but right now I am really really satisfied. I LOVE both these amps and would not hesitate. They may be out of your price range but it took me 20 years to finally to be able to acquire these so there is hope. The wait was worth it.
