MA12070 implementation’s superior against the usual TPA3255 fare in its price zone. IMO, w/ SQ- this competes w/ the Cambridge AXA25 & the like.

Bass control is superb & imaging’s tight. Hiss was present for the first 2 wks but disappeared after.. now w/ fancy power cbl & ferrites jic.

Spruced it up a bit— there’s wayyy too much font on the unit. & the knobs I received was roughed up, easy fix on both for the value prop.

This is just an amazing amp for the price and the good sound quality it produces, and at that price! I have my first one hooked up to my Criton CSS 2TD-X speakers I built and it sound really good. More power than I need and sounds better than my full size Pioneer Integrated Amp. Bought another one for my garage with some smaller bookshelf speakers I built and great sounds out of my garage. :-) Just bought two more. Giving one as a present with some speakers to a friend. All your basic needs are this amp, some speakers and a phone to blue tooth your music from. Most inexpensive good sounding stereo system I know of. Putting the last one I just received to use with speakers in my home office. So yes, I am a big fan of this amp.

I really enjoyed the IA255.1. It fit my needs perfectly and the sub woofer output with the crossover switch was very well done. Great feature set and small form factor fit nicely in my home office. Needless to say I was disappointed when it died after a year. Fortunately the warranty covered a replacement and RSL’s customer service was terrific. I sent it back to RSL and they sent out a replacement. Oddly and to my surprise the replacement was also bad and I gave up on it altogether. Maybe the next gen will have better luck. I have had zero issues with other small chinese amp brands in the same or similar set ups. Hopefully just a bit of bad luck on my end. I want RSL to be successful in this space and keep offering these type of products! In any event while disappointed with the outcome, I did like the product a great deal and hope as time goes by it improves so I can revisit it down the road.

I love this amp. It's primary home is in my garage paired with RP-600M's and a Sub. Very easy to move the IA255.1 to my outdoor setup which does not have a dedicated amp as there is no "whether proof" spot in my pergola. Super clean sound and it works great!

I love the size, and it powers the speakers well. Good sound. Light, so you can take it with you. I wish though.. and I hope they're reading.. that they would include the cable to go from Amp to Subwoofer. At one end, it's a minijack female OUT.. and usually at the subwoofer, it's a female RCA in.. I figured it out.. but even a link of exactly what to get would help. I used a minijack adapter (gold) to a shielded long Mono RCA cable. But everything else, great.. and wonderful customer support.
