surely any commercially mfrd amp will be capable of handling 200 w. 
straight through.

i might not run a kw through one, but if an amp is made to not handle 
200 w. throughput in bypass mode i'd say that amp raises "built on the 
cheap" to a new level.
btw i use my mk V to drive a TT Centurion.  I have run 180 w. pep 
barefoot through it from day one without ever even considering this 
might be bad.  no problems so far and it's been 18 months now.
