Lol, well the Lepai arrived all the way from China today along with the Mission speakers. The speakers came in the original box and are cosmetically perfect which is remarkable for a set that this over 20 years old.
The 2A PSU supplied with the Lepai does not go all the way into the plug socket. Rather than sitting flush there is an about 7mm gap between the faceplate of the socket and the base of the plug. This is not cool, but it works. I have emailed the store (radioddity) for their suggestion here. Still there was always going to be some kind of issue with an item that cost £16.84 delivered!
I hooked everything up through some horrid old bell wire style speaker cable and used my phone (a Samsung ATIV S Windows Phone) as the source. This plays MP3s that are ripped from FLAC files to the Standard, Fast LAME preset through fre:ac.
First thoughts were that the bass was absolutely non existent! The speakers don't go that deep (down to 70hz) and are small, but there was nothing coming through at all at the low end of the register. However, things might be starting to loosen up now. At the top end things are nice and crisp without being overly bright. I do want some more weight and emphasis down low though.
It will be interesting to compare the Lepai with the SMSL SA-36A that I decided over instead of the Muse. The plan is to fix up the B&O speakers and use those with my computer with one of the amps instead of the Creative T20s I currently use. Those are fine for TV and film, but aren't great for music. However, I am slightly concerned that they might be a bit difficult to drive at low 80s impedance at 6 ohms. Oh well, we will see!
