Please see the review below for the ModWright Instruments KWA 150 Signature Edition Integrated Amplifier.

The KWA 150 costs $6,995 and delivers 150 wpc into an 8 Ohm load, or 275 wpc into 4 Ohm. The ModWright KWA 150 Signature Edition costs $8,495. These prices came from the above article.
I am surprised the units power does not double going into 4 ohms (275 wpc instead of 300 wpc). It is a heavy unit and must have a large power supply. Comments? Is the KWI-150 SE a balanced design? If yes, it should have two XLR inputs instead of one.
These prices are high for me but I would interested in hearing owners comments on the KWI-150 SE unit (or the KWI-150 unit).
