I have love Carver Amps Since the early 80's . I have from the original m400 Amplifiers serial # 0022, two 1.5t's, one m500t, TFM-75 and now a 300x 2 Sunfire And each has there own sound.
For what it worth if you buy a carver Amp and the" best for that amp speakers" than you have a great set-up.
I have never owned a TFM-15cb but had a friend that ran his big Polk SDA's with them. and loved them with this this combo.
Just make sure I you do buy a used Carver Amplifier that its as mint as you can get condition , as the magnetic coil is no longer made and hard to find.
If you realy love music you owe it to your self to give a Carver a listen .
