Magnepan MG20 tweaks ?

After reading this I am interested in the Apogee's. What are their newest models, and can I get an audition of them in Houston, Chicago, or New York?

There are several brands of capacitors. I would not say that Intertechnik Plus is the best, but they are easy to get and the sound iis marvellous too. Also the coils have different name, I choose the aircore inductors. Again they sounds like heaven! see www.humblemadehifi.com/Cap.html
A friend of mine has his MG 20.1 modified with Intertechnik Plus. Heaven!
Please bear in mind I wrote Intertechnik Plus, the better Intertechnik, not ordinary Intertechnik.
Do you want to have the "best" MG 20 than choose the electronic crossovers from FM Acoustics, specially made. They cost a lot!

I would recommend bypassing the Magnepan crossover and using the Bryston 10b Sub active crossover--much cleaner than the standard Magnepan crossovers (although the MG20 one may be better--I don't know). I use it with MG3.6r's and Pass Labs amps and it sounds great.

You will find everything necessary for passive upgrades here: (http://www.percyaudio.com/Catalog.pdf) Michael will also match that parts to 1% tolerance for you. If you were to bi-amp the panels: I'd recommend a slightly modded Dahlquist DQ-LP1 as the active hi/lo pass filter. They are getting rare, but well worth seeking out. There's a good description(on page 13) of the unit here: (http://www.avahifi.com/root/audio_basics/ab_pdf/ab1989.pdf ) Do you own the 20R or 20.1? I can send schematics if you don't already have them.

Hi Batalok. Thanks a lot, I started to check the www.humblemadehifi.com/Cap.html but they is nothing on Internet (nothing too with Google). But I found a French seller. I will ask him.
For the cross-X, I think that FM Acoustic will make the best job but cost a maxx!
I'm seriously thinking about Pass Labs CrossOver in the futur.
