Integrated Amp to match with Magico A3

I think 300 is just a minimum reference. Since the construction and design of the driver are rather demanding, I think high damping factor amplifier is what I think required.

I evaluated the S5's in my search for a new pair of speakers.  My local Magico dealer had the S5's attached to a powerful solid state amp with an extremely high damping factor, when pushed hard, the S5's "came to life".  When their "high end room" became available, the moved the S5's into that room and attached it to a tube power amp, and the speakers sounded MUCH better, had more bass, smoother highs and didn't seem to be driven as hard (as with the solid state amp) to "come to life".

Go for a Rogers EHF 200...Lifetime warranty, so there is the extra pressure to stay alive. Another note...a pic from someplace of a Magico factory tour showed a QSC GX3 300 watts PS pro power amp on a shelf...I wonder what they use that thing for. I have one of those for live stuff I do, and it's amazing...cost less than 300 bucks new.

Do you realize normal listening volumes are 5 to 10 watts. If you think your listening at high volume to high power, then put a wattmeter on wall plug to measure actual power and you may be surprised. Most people will say ya ya. Try meter, and prove it too yourself. Most people don’t have a clue. A lot of amps distort like crazy, after there in there middle volume levels. The 50 watts minimum rating on A3’s is only a guide. Vitus Audio amps are way under rated power. Vitus Audio uses custom patented UI core transformers. Max voltage drop is 3%. Almost every other amp uses Toridal transformers, with a 25% voltage drop. You do the math. My Vitus SIA-025 MKll go very loud, crytal clear, non fatiguing, great. Let’s do some math. Every 3db level is double power, but only 1/10th greater for human hearing. Our hearing is logarithmic, and double listening levels is 10 times power. This means if your listening to 50 watts RMS, will take 500 watts RMS to hear double. These are facts. Once again, 99% of most people listening levels use less than 10 Watts. Don’t get sucked in. Exception would be low sensitivity speakers.....ie 85db. Anyway, Magico A3’s are pretty efficient at 88db. I had high power Bryston, Krell, Passlabs amps. My Vitus at loud levels blow all previous amps away in SONIC BLISS. The three previous amps aren’t in the same league.

According to hifiplus - Alon Wolf himself recommends the Hegel H360 (source: http://www.hifiplus.com/articles/exclusive-first-listen-magico-a3/). I don’t think you will get a better recommendation than one from the founder of the Magico. That being said.. for what it’s worth I demoed the A3s with that amp and ended up ordering both. There are plenty of reviews of the H360 out there if you’re interested. My review would be summed up with two words: "effortless power".

Cheers!
