Integrated Amp to match with Magico A3


Have just ordered a pair of Magico A3, and looking for integrated amplifier to pair with it. As I heard once which had a very disappointing result to pair with Gryphon 300 in a local Hifi show in Hong Kong. Reallly looking for recommendations on matching amplifier. Planned to get a Marantz PM-10, but worried that the single box may not be powerful enough to push the A3. On the other side, some said Hegel H360 with 4000+ damping factor may suit even better.

thank you in advance

My integrated amp I use with my A3’s, is the Vitus SIA-025 MKII. The sound is incredible. If anyone has the means, I highly recommend this integrated amp.
Amazing. ⭐️⭐️⭐️⭐️⭐️
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.
BOTTOM LINE YOU GET WHAT YOU PAY FOR, LIKE ANYTHING ELSE IN LIFE. Siltech



Next time you see Alon Wolf, ask him if Hegal is better than Class A amps such as Pass Labs, Gryphon or Vitus. Better more, bring your light weight Hegal to any of the above dealers and compare. There isn't any comparison. 
I used Class AB amps for 20 years, because cheaper than Class A. I learned my lesson. All my friends that hear my stereo are blown away. Forget AB
Hegal is a Class AB $5700 integrated amp. I think a 25k
Vitus Class A integrated will blow it away, don't you. I doubt 
the Hegal is in the top few integrated amps in the WORLD.

Hegal tries to eliminate crossover distortion which all Class AB amps do. You can try different methods, but still impossible to eliminate. Any Audiophile should no the only way to eliminate it 100%, is using true Class A design, not AB. Crossover distortion is when the audio sinewave switches from one half waveform to next half. Yes Audiophiles, this is audible. Once again, only Class A dosnt have crossover distortion because it always running full power. This is one of reasons Class A sounds best. Virtually all Ultra High End Audiophiles use Class A amps. Now a days Class A amps are much more efficient, and radiate less heat. If you want best possible sound, Class A in solid state or tubes. Also, the rest of amp has to be there ( Gryphon- Vitus )
Hegal is only mentioned because cost combatabity with Magic A3's. 
($5700 with $9800). Oviously if you can afford a better amp, you'll get better results. I doubt 99.9% of people on this forum no more than myself in Elecronics. Read and learn.
@AudioTroy. 
Thanks, I understand where your coming from. I was just messing around a little bit. My Vitus actually replaced a Pass Labs Int-60 amp. I just couldn't get use of the treble, sounded on bright side to me. Now with Vitus, sound is slightly warm, yet micro dynamics still there. Anyway, most important is synergy, and what your buget is. Take Care.   Siltech

i wasn't degrading anyone. I'm a electronic technologist, and Audiophile for 30 years. I can easily hold my own pertaining to electronics. I always change equipment, and everyone has a opinion. CHOW
Thanks @ kw6
Yes 6 WATTS.
I used to own a pair of Sonus Faber Guarneri Mementos speakers. There measured sensitivity were 87db, and I drove them with a Krell amp. To me they seemed like a 86db speaker, hard to drive.
The new Magico A3’s seem pretty easy to drive, and I think there measured sensitivity is just under 88db. Not hard to drive at all. Actually, l find mine easy to drive loud. The new Magico A3’s are a very good
speaker. Love Them.

  • I own a World Class Vitus SIA-025 MKll, yes the $25300 US integrated amp. I’ve owned may separates and this betters them all. I agree separates better 99% of integrated amps, but not all. If possible go a Vitus dealer and check it out. I use to be a.doubter, till I bougt one of these Vitus SIA-025 MKll integrated amps. These amps are built to last a lifetime, and uses best to possible components in the World. The sound is incredible to say the least. No Short Cuts. The price for sound and quality is a bargain at $25K US.

I only listen to my Vitus SIA-25 MKll in pure Class A mode. It goes more than loud enough for me.

I would say in Class AB mode, 
RL-101 is better. In pure Class A mode, Vitus SIA-025 MKll is easily better. 

The Vitus Rl-101 is a World Class amp, and will sound great with A3's with control. 😊
