Any pluses or minuses to the older McIntosh mc275 compared to the newer mc275's IV, V, VI?


I've got Klipsch La Scala speakers & want to get a McIntosh mc275 amp. There are a couple of mc275 IV's on craigslist right now. Are there any advantages/disadvantages to the older ones over the newer ones? Yes, new is new, but then I'm thinking maybe they just don't build 'em like they used to? And I might upgrade to Klipschicorn's in the future... Thank You!    Bill

The MC275 is a great match for La Scalas or Klipschorns!  Series IV, V and VI are all identical internally.  IV and earlier have smaller spade-only speaker terminals while the V and VI have larger bullet/spade combo terminals.  IV, V and VI all have balanced and unbalanced inputs, but only the IV has adjustable unbalanced input gain.

Good luck & happy listening!

I heard that all MC275 amps have no balanced circuitry (are single ended internally). As to upgrading to K-horns, I believe the La Scalla’s drivers are identical to K-horns but their cabinets are about 12 inches smaller in all dimensions (give or take). FYI: I’m a happy La Scalla owner! I use a BAT VK-300se integrated (which continues to amaze after 12 years).
Isn't the 275 a bit of overkill?  I've had Cornwalls and Hereseys and 7 watts will blow the windows out.  One plus of Mac amps is the softer "tubey" sound since horns can get fatiguing...
