"I had a good listen to the Amp the last two days , for around 6 Hours and I'm very impressed with the sound . My Marantz PM11S2 I thought was very good , but the SDS 440 blow me away , everything was much better then I ever heard before , from the top to the bass amazing detailed never heard the bass so controlled and the hights so open and clear, wonderful . Have to listen a bit more and I will write a Review on your site , just please , my english is not perfect .

To understand where I coming from, HiFi is my hobby since 1980 and and in that time I had Mac Intosh , Audio Reserch , Theta , Accuphase ect and various Speaker , but I never had a better sound as now with your Power Amp . Before I decided to buy your Amp I was ready to buy the Marantz Power Amp SM11s1 ,AU $ 8000.00 ( everything is very expansive in Australia) I was listen too it and find not a big difference to what I had , then I searched and found your site, been reading Reviews from other Class D Amps before and found them overpriced , but decided to buy yours not because Price and Im more then happy now , thank you Tom."

"As you maybe remember I've bought a good second hand Audiolab 8000P in very good condition.

Pre/pro I use is the Marantz AV7005, I use a Logitech SB with a Marantz NA7004 as DAC in between some Audio Quest and Apogee cabling and an upgraded Power supply for the SB.

My current speakers are the new Wharfedale Jade 1’s with the Wharfedale stands, very good speakers but with a low 86 Spl/w and some low R issues...

Well and now for the difference between the Audiolab and your Amp....

Even straight from the box it is a very big leap forward from the Audiolab, sounds like you did some tech magic wow..

Effortless power, wide and deep sound-stage and the high’s and mid’s are much cleaner than the Audiolab, with a lot of details, you get wrapped in sound and the trap is that you want to turn up the volume too much

Even the low Spl of the Wharfedales is no problem at all.....

Forgot to mention that the bass is very easy to follow and goes way deeper (without any boom) than the Audiolab.

In short, I forgot the waiting and could only say I would do it again as I know now that this is a Hi End bargain of the year

Veryyyyy happy with the Amp, my congratulations for the design and build, you did some things outstanding."

"My SDS-440C amp sounds amazing! I have been playing some Jimmy Smith FLAC files and I now hear a level of sound-stage and clarity that I've never heard before. I am just blown away by the quality of sound created by your amplifier design. The sound reproduction is far superior to any tube gear I have used over the past twenty years."

"I've been listening to my SDS 254 for a couple of weeks now, and it just seems to be getting better and better...I just wanted to say thanks for a job well done. The liquidity, the layering, the downward dynamic range, the bass...just incredible...I'm enjoying my music like never before."
