Thanks for the advice on placement of the SHL-5. I figured out the speakers will sound better with more space between them as I initially got a rather congested, or should I say restricted soundstage when I placed them about 6 feet apart. After I moved them further apart, the soundstage opened up and the sound became more natural. Maybe some day when I have the opportunity I will move them to a bigger room and get that elusive 7' separation.
I have been digging out most of my old CDs from the racks and was stunned by the musicality, coherency and neutrality of the Super HL-5's. Some of my unlistenable CDs are now pretty acceptable on the listening scale. I popped in one of the mass-market crap that I got some time ago which was only played less than 30 minutes before it was put aside and never played again, and the results were pretty remarkable. The album was by Gwen Stefani(don't laugh). When I played my favourite track "4am In The Morning", the vocals sound a lot more natural and believable. Unfortunately the horrendous amount of digital bass still ruins the whole thing. All other types of music sound really good. Most important, the tonal balance and timbre accuracy have been superb with the SHL-5. I think I have made a right choice in choosing the Harbeth.
I've read that the LFD and Lavardin amps when paired with the Compact 7ES-3 are a match made in heaven. I am wondering whether these amps will sound better than my Plinius amp in driving the SHL-5 or not. I've checked out the Lavardin IT integrated and it's a rather well-built unit.
