OK, here is my brief review. Other components used were Sony Carousel CD player, Spectro Acoustics P-101 pre and Mission 74 speakers.
I had already sent my other 700b to Lee, so I couldn't do any A-B switching to compare the amp with an old one. I had to use my recollection of what it used to sound like. I used a CD track I was familiar with. Michael McDonald (yes, the Doobie Brothers one) - Motown. Track 4 - I'm gonna make you love me. 2003 - Motown Records
Bass = was a lot tighter, more punch Mids = I would describe them as being more open, airy. Hi = my speakers have been reviewed as being bright at the top end and I attenuate them a bit on the pre. Truthfully I can't say I hear any difference, but I would suggest that might be due to my hearing.
Overall the sound quality sounds exceptional to me. I guess in the end that is all that matters.
