Musical Fidelity A1 I


What is cost to have repair center recap and replace volume knob on an A1 amp? And what is a fair price in that amp? The volume knob is missing and much of the lettering near the control knobs has worn off. Should I maybe look for a newer model with less wear? I need an amp $500 - $1000 used or new for Triangle Altea ESW speakers and Oppo 105. I want to make the right purchase so Triangle's sound good. Thanks! P.S. I know squat when it comes to hifi gear, systems, etc. Do I need additional gear to play my CDs and SACDs?

Thanks Russ. The M2si is $1000 new vs M3si at $1500. Same watt amp minus the phono and dac. What advantage is there with the M3si? Would the dac better than the Oppo Sabre dac? Much appreciated! BTW what Triangle speakers do you have?
Good for you second guessing that particular used amp. It sounds like it’s had a hard life!  
Yes, there are a lot of uncertainties with a 35 yr unit. Ok my new thread in the amp section, russ69 has shared that he owns Triangle's. I feel his recommendations are sound. Just not sure if I need a better dac than my Oppo Sabre dac, to get better sound from my SACDs. Want to do it right the first time if I can. 

My mistake. It is in this thread that russ is helping me. I really appreciate both of you. There is a lot of technical information regarding this hobby compared to my other hobbies. I need to read more!
