Review 1 of 1

Price Paid:  $1650.00 from full compass

Summary:
This is a professional power amplifier, the specs are as follows:

8ohm-800 watt
4ohm-1250 watts
2ohm-2000 watts(very stable)

THD is lower than .02% at FULL power and about .005 at half rated power

damping is a nice 500 at 4 ohm, so at 8 it must be at least 800-1,000.

I am driving a pair of Axiom M-80 towers with this godsend Amplifier. I must say, this blows my Rotel 1090 and my Krell ksa-250's into space. and the Rotel is rated at 780 into 4 ohm.

at first i was skeptical about using a pro power amp other than Crown, as I used 2 crown studio ref 1 at bridge mono for years, and was BLOWN away at the sheer brutality and sound of these amps. The QSC pl 340 is not as powerful but has a much better overall sound, the highs are better and the midrange is a bit heavier. but the Crown smokes it in bottom end I think, as my setup was quite diff from now and then. so unless i have them side by side i wont know. but the sound quality is just great, the bass is chest heavy, and slams you right in the sternum, as tyhe midrange just flows like a liquid guitar, the highs are very real, as GAry Moore's guitar was singing to me like I never heard it before, also heard sounds never before heard on my Krell( yes its true ), the amps NEVER sound fatigued at any time of my burn in or listening, never seen the clip limiters once, and my neighbors came over just to see what was the ruckus, and my doors and windows were closed. I also borrowed this amp to my cousin who is in college in Southern Illinois university for a party, he said his roomy had this amp running just below clipping for 13 hours straight with 4 speakers hooked up, and not once was there an interuption of the program.
The amp was returned about 2 months later, and in the same cond(small scratch on top ) than what i loaned it. and it actually sounds better than when I first listed to it. The burn in time from the beating it took at a dorm bash sure helped the sound. The bass this time around was very detailed and just direct thumps, i was amazed at the detail. The speakers were effortless in producing the massive input of watts and current. Everything just seemed to flow together, I havent beat the amp nor loaned it out as i wont do it again in the future, but safe to say I am very happy with this amp. buy one abd try it out, unless your a strict vac tube guy, then maybe this is not for you, buut if you like lots of headroom and clean power, and have spent thousands and thousands on Krell, Mcintosh, and the like, give em a try, I think youll like the sound, although not as visually stunning at Mac stuff, they do have a great sound

Strengths:
Very open airy presence when at idle music level.
Lots of clean power
highs, mids, and lows are all VERY solid and have a warmth to them,( YES they do!)
nice removeable attenuators to fit a screw down faceplate for protection of kids or nosy friends.
ok for a regular 15, 20 amp home service.
when the faceplate is on the looks are quite nice.
small size, makes it easy to hide in closets and such w/ out the chance of overheating due to the internal fans.

Weaknesses:
has a fan, not very noisy, but if this is not your thing......
small-I like my amps to be beefy looking,but the power/size ratio is unbeatable

Aune Mini Headphone DAC User Review

The unit arrived from China well packed and everything seem to be in place. No external abuse by the carriers. The only problem was the power supply it came with. The box came with a cheap step-down converter.
