These amps are designed with a separated power supply, three pieces with two monoblocks and one power box. These beautiful amps, are designed for human ears, not for testing equipment, produce superb resolution of all level details, and gives spacious soundstage and pinpoint imaging with wide-ranging, open, extended highs with a lovely liquidity. Each amp has a volume control and accepts wide range of level inputs (CD, Tape, etc.). So it is "integrated amp", but it also accepts a feed from any preamp (just turn down the volume if your preamp's gain is too high). So it also is a Power amp.
