suggestions for a studio monitor amplifier.

audio_moksha · 15th March 2008, 05:28 AM

Hey guys, I'm looking for a solid state amplifier schematic for a high quality studio monitoring setup. My requirements are low phase and inter modulation distortion,high damping factor and excellent frequency and phase response. I need about 50 watts rms. In a nutshell, I'm looking for a very neutral/accurate amplifier and by budget is flexible.

I have designed and built quite a few tube amps but when it comes to chips and PCB's im a total noobie. The monitors are going to be a three way d'appolito styled mid fields and I will be tri amping it with an active crossover. I would greatly appreciate suggestions for schematics as well as how to implement it with a PCB. Many thanks in advance.

Most monitors use some form of chipamp - but that's on another board. Schematics for those are pretty easily available on the board itself, with a number of options and in some cases, it's easy to pick up PCBs from other members/kit sources such as Peter, Brian etc.

On the discrete front there are the AKSA kits from Hugh (but those are kits, no schematics available), the Studio series which uses older semis, the newer Symasym, the Rod Elliot PA03 series and variations - and a bunch of others. Read up about them and you can make a decision.

If you have the luxury of full biamping like a real set of active monitors, I would use multiple chipamps, maybe in bridge/parallel to increase power. I have a similar setup driving my Dynaudio BM6 passive monitors. I suspect in super-quiet environments you may need a better system, but I mix at home so it works for me.

Hey Sangram thanks for the reply. Where in bombay are you from? I'm from Malad. Haven't been home in 2 years. Definitely miss the vada pavs ; )

Live in Bandra...

Another option I remembered is the SKA. Greg supports them well, but you'll have to hunt him down AFAIK he doesn't post here anymore, but there's a builder's thread somewhere.

Lynx amplifier 3.0
by Jan Dupont

with lower supply unit maybe at +/-30V only.
