Not noisy, not muddled, extended as all get out, and definitely powerful...the M-1s blew the internal protection fuses on a set of Jeff Rowland 735 monos before a moderate listening level was reached...in other words, the M-1s are demanding!

The little digital amps will in this instance drive them to uncomfortably loud levels with no distortion.

The change from day one to day two was significant, stridency diminished and depth and image location improved.

It ha been my experience with digital amps (ever since the  Sonic Impact days!) that they take a while to fully settled down and show you what they are capable of, so I'll leave these guys running for a while and see how they progress.

So far the guy whom I bought these for just laughs because he feels like they are stupid good for chump change...

Hmm, Since my main use is as subwoofer amps, it seems like they may fit the bill. One of the main criteria is power, many people including me at the moment, use pro amps for subs. All I will need is a C&C 1 or 2 in, 2 out DSP.

If I use them for other purposes I might drive them with a tube preamp I have. I'm thinking I may test them with a pair of Carver ALS as they are demanding speakers as well. Carver recommends 800 watts I believe. I am currently driving the ALS with a 100 watt NAD amp.

Got the amps unpacked yesterday and hooked them up to a pair of Soundlabs M-1s:


I pulled the trigger on the amps. How long did it take you to receive them after your order?

About two weeks is average for stuff from them, sometimes it comes sooner than expected...

I ordered a second pair of tubes for these amps I have that use paralleled 300Bs earlier this year with a two week shipping estimate, I had bought a pair previously and I was pleased with them so I ordered the second set...and after a month went by I inquired about the late shipping, etc., and they surmised they got lost in transit and gave me a refund...so, I ordered another pair that showed up quickly....nearly three months later the "lost" ones actually showed up...

I ordered a preamp for the guy I work for, and it ended up being delayed again and again, so I inquired about it and was given a refund without any problems...

Shipping is definitely not Amazon Prime level...well, I bought a WiiM ProPlus on Prime day and it still hasn't come, but that's an exception, and I quit worrying about ordering from AliExpress.

I just wait and I'm pleasantly surprised when the stuff shows up.

Well, I got them in. Two comments about the packaging;

1) They are wrapped very tightly in plastic. This makes opening them difficult and I scratched the top of one.
2) They did not come with power cords. But they are standard NEMA 5-15P to C13 power cords.

Once I got beyond that, the fit & finish were good. Absolutely no manual or lettering on the amp other than serial number sticker and 115V sticker. But what do you need? It's a mono block a power switch on the front an RCA and XLR for input and binding posts on the back. The only thing they could use is a label on the switch between balanced & unbalanced.

Hooked them up between my WIIM Pro and Magnepan .7s and let them run for about an hour in another room, while I ate dinner and watched the doom & gloom news.

When I went to listen, I DB matched a pair of Magnepan 1.7is I just repaired which are hooked up to a NAD 2200 PE stereo amp.

It may be me and new toy bias, but the noname amps seemed to have better control of the bass and didn't seem as stressed at volume. The original purpose of these amps is to drive 18" Ultimax subs, so I decided to crank a few songs on my Maggies. I played some ZZ Top, Dire Straits, Cream and a few other classic rock tunes at 96 DB peaks with no strain or bass bloom.

So after my 1st hour & a of half listening I am quite impressed.

I, too, noticed the bass control on a set of Aerial 10Ts...
