This amp is just a few years old and barely broke in. This is Dan's flagship SOTA solid state amp. I got it directly from Modwright and have enjoyed it immensely in the time I've had it. I've been using it with Dans amazing PS/LS 36.5 dual mono preamp which I am also selling. Sadly life changes have just not allowed me the indulgence in listening time as I once had, and other expenses are looming on the horizon. So it is with a heavy heart that I let these go to a new owner. Everything you'd need to know about it in general is on the Modwright site
http://www.modwright.com/products/kwa-150-signature-edition.php and various posted reviews where praises are entirely justified. The amp is in excellent shape and functions flawlessly and I have the original box and papers. Shipping weight is about 85lbs and local sales (Seattle) are favored but not necessary. MSRP is just under $9K. Mine probably has about 300 hours of use - $6k (net to me) + shipping. Discounted for cash and carry local sales. I will add photos or send them by request. I have ample feedback on Audiogon under Jax2 and Dan Wright can also vouch for me. I'm happy to answer any questions - better to email jax@nwlink.com
