In Reply to: RE: Musical Fidelity integrated- PS cap upgrade cost/benefit? posted by airtime on May 25, 2015 at 15:54:24
Have decided against the PS cap upgrade based on advice given here, but the resistor idea seems good. Will check. Unit not in need of restoration, just wanting to do some upgrades if cost reasonable and relatively simple and effective.. Thanks for the tip.

If the resistors are already metal film then as stated below - leave it alone.
I don't know if you can eeeck out more from this amp without "experimentation" and eventual "destruction". Been there! Just leave it to be rebuilt at the appropriate time by a pro!!!!
If you are just not happy then consider another amp or even preamp.
Don't waste your time with this either. All the resistors are metal film,and of good quality. Also really fussy to replace.

Hi, Mark,
I've been reading this thread with interest because I've been using a MF A3.5 integrated since 2007 and have been enjoying it a lot. It's been the only pre/power source through upgrades in the turntable, phono stage and cartridge, a CD player (including a tube buffer and DAC), and speakers. With each change in the system I could easily hear the improvements in sound. (Well, one speaker "upgrade" turned out to be a downgrade and I quickly replaced them with a true upgrade.) So good or bad, right or wrong, my stereo has basically been built around the A3.5. All I can say in my defense is that the system sounds very, very good and I haven't had the urge to upgrade anything for some time now.
But, I know that the A3.5 is getting older and have wondered what an upgraded pre/power source might sound like. Trouble is, I'm not sure what the next step up might be in a modern integrated amp. Parasound's new Halo Integrated? I'm not in any hurry to find out and I may decide to go ahead and have the A3.5 rebuilt when the time comes. What have you been considering?
Regards,
Tom
Hi Tom- glad you posted!
This thread has likely given the impression that I'm unhappy with the 3.5, but honestly that's not at all the case. It's a great unit; normally it's used in my back-room system though now it's doing temp duty as the bass panel amp for my newly bi-amped Maggie 3.6's until I pick up something more ideal. Anyway, the fact is that most (all?) non-cost-is-no-object components like the A3.5 are built to a price point, with good-to-very good, but not premium, parts inside. So, just as a fun project, I was looking at making it perhaps even just a little better with some parts upgrades, as people often do with other components. Probably won't now, based on advice here; no sense in wasting money for nothing.
As regards possible replacements, the Parasound and the newer MF's would come to mind. But refurbishing this one would certainly be very acceptable.
