Amp newbie? Adcom GFA-555 vs Mcintosh 2505


Hi I'm definitely a newbie, and already know my initial choices in starting my first adult sound system will make experienced folks around here cringe...but I'm wondering if I might still garnish a bit of insight to help reduce additional "bad" choices or steepen the learning curve just a bit.

From the beginning; I went and auditioned speakers at Best Buy, and of course fell in love with Martin Logans...and decided to order a pair of Magnepan MMGs (not a bad start right?). Did some research and bought a HK3490, maybe not the wisest choice...kind of wish I had started with separates...but it should be able to handle the MMGs...I know I amjumping the gun a little because I have not even heard this combo due to some shipping issues with Magnepan...but my question is this...I'm thinking I can use the HK3490 as my preamp and add a separate amp?

And the real question how do you compare amps...I am looking at a few intro. affordability choices like the Adcom GFA-555 rated at 200w/channel vs. the Mcintosh 2505 rated at 50w/channel...but I'm under the belief it's not just the watts, but the amps that are driving them...otherwise my HK3490 at 120w/channel should have the juice to power the maggies...so how do I know which will deliver a better sound for the buck...and more importantly...how many watts do I really need?

The receiver should be fine with the Maggies. While Maggies do like a lot of power, those are small ones. You should be okay there.

Now when you go off the deep end for bigger ones, which you will, it's nice to have preamp outs on the receiver so you can just sub in another amp.

The Mac at 50 wpc is clearly not going to have the power for bigger panels.The Adcom, nah. I've found that while Adcom preamps like the GFP 565 can be really nice, the amps tend to flat and boring. I'm overgeneralizing there but there are a lot of used power amps out there. Enjoy what you have for a bit before you join the amp of the month club.

Your newly found sickness, and that's what it is, is not easily cured.Best of luck there. Remember though, you could be drinking, gambling, or chasing Women...
