I had the Cadence in my system for about 2 years and found it a very flexable piece with overall excellent sound. I upgraded to a Manley Steelhead to get that extra tube bloom and extension. Probably a matter of personal perference of tube over a solid state design. Only drawback of the Cadance is that it does require it's own power supply or can be shared with the Jeff Rowland Synergy's power supply. The Rowland Model 10 amplifier has been the only permanent piece in my system over the last 5 years.
