I first plugged these into my Decc-o, which was running my Chorus IIs at the time and was surprised at how loud and good it sounded with only 50 watts, though no where near as loud or authoritative as with the Chorus IIs. Then I busted out the TGP-II / M-1.5t combo I'm selling for a friend of mine, a big improvement over the Decc-o but the amp seemed strained even at moderate levels. I switched the amp with my refurb'ed TFM-45 and that's when the "magic" began. Now I'm hearing clear depth to midrange and nice, airy highs. Bass is different then I had imagined, nice tight bass through the spectrum though not overly pronounced and reaches down quite a bit lower then the Chorus IIs.
I'm listening to "What's Your Name" by Lynyrd Skynyrd at fairly low volume and everything is there and very well balanced. "Dead and Bloated" by STP just came on and again, very clear, can hear the cymbals, different drum beats, bass guitar and vocals are all very well balanced, very enjoyable to listen to. "Don't Stop" by Fleetwood Mac from their Rumors album, piano is very clear and sounds real but bass sounds a little weak on this track.
