Upgraded from a 200wpc Class A/B amp to 35wpc Class A
Upgraded from a 200wpc Class A/B amp to 35wpc Class A
So I got a
MF AMS35i 35wpc pure Class A amp to replace a
MF M6i 200wpc Class A/B amp in the living room about 2 weeks ago. Here are some pics.
AMS35i (left) and M6i (right) side by side.
The grand grand grand pa, a modded (new capacitors and op amps)
MF A1 20wpc Class A amp I have in the bedroom in the foreground, M6i behind it and AMS35i on the equipment rack.
Massive heatsinks on the sides that get too hot to touch for more than a few seconds.
The whole 2.0 setup.
Most people must be thinking "WTF did you "downgrade" from a 200wpc amp to 35wpc?" TBH, I was also a bit skeptical about this move at first. After all, this 35wpc AMS35i costs over twice as much as the 200wpc M6i. But I must say that I'm pleasantly surprised at the result. Not only has everything I listen to become more musical (love that piano, violin and human vocals that is more tube like), but it is also more analytic which allows some complex classical pieces (e.g. Tchaikovsky's 1812) which somewhat sounded like a mess on the old amp to play with ease. However, the most surprising thing is that there is a very noticeable improvement in bass. That's right, there is more bass from this 35wpc amp than a 200wpc one. Never knew that the woofers in my
VA Beethoven Concert Grands can sound like that in old school jungle / drum and bass tracks. Obviously, this is no replacement for for a proper powered subwoofer, but IMO it has come a lot closer.
To conclude, the specs would seem to indicate the new amp is severely underpowered but in reality, it seems to be better than the old one in every aspect. Well, maybe NOT power consumption and heat coz this amp generates a sh*t load of heat and consumes full power the moment it is switched on even when idling. The downside with that is I need to turn on the ceiling fan and a/c after an extended listening session, just like how I need to turn on the a/c in my gaming room.
But if you have reasonably sensitive (say 90db or above) 4ohm speakers (the amp's output increases to about 60wpc at this load), I would suggest an audition of a Class A amp for a 2.0 setup. Don't rule it out simply because of the seemingly "low" power output.
