This thing is tiny - like the size of two packs of cards. It is also extremely light; helped by the 12V outboard power supply. Build quality is just okay. I'm not a big fan of the spring clip speaker wire connectors or the tone controls; which can thankfully be bypassed. The light-up volume control is gimmicky too but no real major complaints given the silly low price.
In my garage system - replacing the venerable Adcom 545 - I was surprised how good CDs from the old Pioneer DVD player sounded. There was a toe-tappin' excitement to the music with plenty of kick. The Wharfedale Denton speakers are a good match with this amplifier, making more volume than I expected. There was a nice speed to the sound too. Over all I would give the slight nod of the Lepai over the Adcom, but we are talking a garage system so let's not get too carried away!
I originally wasn't thinking of plonking this little amp into my main system, but given the amount of free time I have due to being furloughed, I decided to give it a try. Initial impressions were rather eye opening. This is one very nice sounding amplifier. But a few minutes of listening, even with my Dual CS5000 and Schiit Mani phono, I could hear a loss of detail and blurring compared to the Aleph J. Bass of the Lepai was also a little rolled off and there was some solid-state grit and forwardness on top. But to be fair, the Aleph cost in the neighborhood of $900 to build; a far cry from the dinner-for-one price of the Lepai.
Conclusions? It's a good amp for cottages, garages small apartments, dorms, or where critical listening is not of upmost importance. I could easily imagine a system with a Rega RP1, Schiit Mani, the Lepai, and your favorite budget mini-monitors. Such a stereo would best a lot of ones that I've heard (or even owned!).
