This amp is really great. The sound quality is amazing, the

build quality is amazing, it drives 4 ohm speakers at full

power without breaking a sweat, and it even looks super

cool! I used a self-constructed power supply that I already

had on hand to power it, and I also used the rotary

encoder board for volume control. Together, these components combined to

make a very compact, powerful, and very hi-fi amp that I use for everything

from my TV to my iPod! Thanks PE!

My Product Recommendations

This ittle amp while small in size is big in performance, i

own 2 of these , out of the box you are looking at 10

minutes at the most to hook up this giant killer.i would

remind you to be sure to flip the small switches otherwise

the amp will not work.i owned a couple of tripath amps i

purchased direct from china ,so i had some ideal of the sound quality, this 100

watt version is really a great buy,and you can experiment with the board etc,

this amp i used a 12v regulated power supply , very simple design , i then had a blind test against a couple of nad

integrated amps, this amp won the sound test, i have since changed out a couple of caps with solen caps, also i have

stiffen the power supply with 2 computer grade caps , i have since ordered 2 more of these amps, i read on line that sure

has plans of a 200 watt version for this year i hope so,i will be one of the first to own it. this amp is a great buy with

great sound quality ,so you can be sure with a sure amp.

Never thought I'd buy a 70W (RMS, low distortion) power

amp for under $50, and under $100 with a 450W industrial

grade power supply.

The amp runs dead COLD at about 30W/channel output

estimated (very LOUD into moderately inefficient closed box speakers). Sound

quality excellent. Planted this in $6 plastic enclosure from Radio Shack. Totally inconspicuous and totally silent when not

playing. Power supply also small. really needs no enclosure though I may give it one for protection. I particularly like the

adjustable input gain, which makes amp compatible with line level preamp. Great product.

Great little amp for the price! It even makes the cheap test

speakers on my workbench sound good.It has a very

detailed sound.I will be using it in a bi-amped speaker

when I get it in a case.

My search is over! I was a little skeptical of this amp

board, but with the rep of Sure products, I ordered it and a

few parts for the power supply. Ordered some aluminum

from Online Metals and built a dream rack mounted power

amp to die for. It is dead quiet! No hummm yah!! The

snubberised 31 volt power supply with 40,000uf bank of caps set the stage for

an awesome combinations that won't run out of gas stated by a previous

reviewer. I'm hooked up to a pre-amp and 10" 3 way speakers that are 92+ db

sensitivity that will blow you away. The mids are warm, the highs send chills down your spine, and the bass is very tight

and deep that rattle the windows. This amp is a dream come true!! You can't go wrong for the money that puts it in a

class by it self. Thanks PE and the tech team for the dip switch combo for the gain that matched my pre-amp, very

important info. Build one for your self. You won't regret it.

This is a surprising amp. Seems to be more poweful than it

is. At normal listening levels, it is as crisp and clear an

amplifier as you would want. IT is dead quiet. At very loud

levels the little amp runs out of gas. I used the 24

volt-14.6 amp power supply. I have yet to get fans to

come on.

This board provides excellent imaging, clean detailed

playback and a wide sound stage.

The midrange power packs a punch, just amazing,

although it might be too biased in the mids! At 100 Watts

it powered every speaker design I threw at it, and all

sounded incredibly beautiful. The amount of high performance audio you get for

your buck is just AMAZING!
