I planned on using this preamp(Onkyo P-304) with my 700B after I finish with my WOPL work this winter. Any thoughts on this Pre or should I keep looking? Never heard anything bad and it's the only Pre I have left for duty since my P-388f imploded. Seems to handle duties in my man cave with the M504 amp. Sounds great to me but after aircraft carrier duty my hearing may not be what it used to be....
