Budget Audiophile Looking For Amplifier Suggestions

Whatever you do get the very best you can possibly afford stretch if you have to.  Great old gear is great stuff. Mediocre becomes. ....,This is a golden rule of buying used and older things.  Think in terms of the best gear you can, go from there.
 I cannot make a direct recommendation because I use tube amps,  with less juice than you need want etc. I once, owned a big MF integrated and didn't like all that much.

If one shows up, a McCormack DNA 0.5 with A Revisions would be a great choice in addition to the many others listed here.  Best of luck. 

I have the Parasound A23 and A21.  If you can find a good used A21, I would strongly consider it.  It would be the last class A/AB amp you will need to buy unless going to a full pure class A.  

Get a new (or used) Jolida tube amp…plenty of power (depending on which model, but everybody knows tube amps don't have to be powerful since they have "tube glow mojo") and a tube amp makes you more interesting than you might actually be.
