SET amp recommendations for Zu Definition II's

Schw,
There`s a recent thread by Afc which compared the Mastersound 845 amp to the Coincident FrankensteinMK2 on his Zu speakers. This may be of interest to you.

I would use the Coincident Technology Frankenstein's at 8 watt/channel and MSRP $5,000. Thy are as clean as a whistle and surprisingly powerful sounding. If one needs more tube power the Coincident Technology Dragon's at 70 watt are also great.

I have been using a Yamamoto A-09S, 300B amp for last 2 years with my Def IIs. I have had no desire to change. I did demo the Art Audio PX-25 before I bought the Yamamoto. I thought it matched up very well. I have seen them for sale here at pretty reasonable prices.

There are Komuro amps here on sale; should be good enough.

Schw, the Mastersound 845 amps are excellent. Lots of grunt. The Conincident Frankensteins are crystal clear. Both are great choices. I'd echo what Glory said. Sean Casey at Zu currently has my Mastersound Compact 845 on loaner duty. He'd probably be able to answer any questions as to how it performs with most any Zu speaker.
