Just picked up a pair off ebay for $100. In a word... Wow! In two words... Very sexy. The build quality and performance of these ancient Lilliputians is outstanding. How come they don't make them any more? They are about 30% smaller than the LS3/5a, but pack more punch in the bottom end by digging about 20 Hz deeper. These are keepers, very easy on the ear. Smooth and detailed. They sound very natural. The foam surrounds are on the brink and will eventually need attention; even so, I consider these to be an extraordinary flat out bargain.
In keeping with the ultra compact concept, I was going to mate them with the Miniwatt tube amp, but they are rated 4 ohms and only about 87 db efficient. So instead I found a used Virtue Audio One and snapped it up. It won't choke the low impedance or run out of steam as quick as the Miniwatt. I think that will make for a much better match.
If you are looking for high performance in an ultra compact mini monitor for next to nothing, these are the ticket. I spotted another pair in Canada yesterday for $150 and scooped them up as well without any hesitation.
