Sounds like the circuitry isn't quite ideal for the 228 (single amp version of the 2228) - appears to be stable (which with a lot of amps it isn't) as he doesn't mention it sounding "grungy" - the mid-range should be significantly "fuller" sounding though not quite as clear as the LME49710 if its working properly. Very much an op amp you can't just drop into most without some adjustments to the circuit so gets written down a lot.
Doesn't mention the veiled signature of the 8065 (single of the 8066) but I'd imagine it is still there :S
