This was my very simple, straightforward two-channel audio system, consisting of vintage components such as my McIntosh amplifier and Klipsch Heritage Series loudspeakers, and newer components such as the AMC and Monster Power units. Overall sonic characteristics of this system was extremely smooth, solid, and transparent, with lots of clean bass (not too deep, but tight and accurate with no boom). The attention was in the details, of which the AMC CD player was capable of bringing out of the music. Clean AC power was distributed throughout my system with the Monster Power, the Cardas interconnects transfered the signal in the best possible way, and the Orbeck speaker cables reduced the overall harshness associated with horns. All this quality and performance, along with a rich heritage and total reliability, made up a system that was thoroughly enjoyable and musical, all this without spending a large fortune! I was totally satisfied...until the upgrade bug bit me and I switched to valves...See my latest system!

I hear the latest Cornwalls are a major improvement over any previous versions, as well they should be since every component has been vastly updated.


Love the simplicity, and I'm dying to hear the Cornwall IV's...


This was my favorite SS system before purchasing my latest 300B SET. And yes, it's a very small room at 12x13.5x8. I've owned my dad's '79 Cornwalls for many years now and simply love their "in-your-face" horn sonics! Unfortunantly, the Klipsch could sound quite harsh at higher levels in this tiny room...the Cornwalls are extremely large loudspeakers; too large for such a small room that they couldn't perform to the best of their abilities!

Since I no longer own the classic MC250 (nor the MC2100 or the MC7200, all fantastic SS Mac amps I've had, nor can I afford an MC225 or MC240), I'm forced due to budget constraints to keep my 8 WPC 300B SE amp (okay by me). I needed an inexpensive full-range tower (no money yet for a sub) that is efficient enough to be driven at higher levels I like with my SET. The Athena AS-F2 floorstanders are less than $599 a pair with a sensitivity rating of 93dB @ 1W/1M; they're not horns, not by a long shot, but they're pretty damn smooth in my room for cones and domes!


This is a nice system - a suppose it is a studio or small room setup. Klipsch are terrific speakers and I am a Mac fan. Have you tried a 240 in this setup?



The MC250 is one of the warmest sounding SS amps I've ever heard, mainly due to their McIntosh patented Autoformers. It's the closest to sounding like a tube amplifier IMO. The detail and dynamics from only 50 WPC is striking! Yes, the two knobs are the gain control knobs for each channel.


please tell me how the mc-250 sounds? I want to know is
of the two knobs are gain also?
