And the answer is.......
It wasn't that hard to guess as many have speculated. The decision was narrowed considerably when it was clear that the Alexx V is not exactly the easiest load for an amplifier to drive. While there was a lot of speculation as to why the CH M10 was a disappointment for me in driving the bass of the Alexx V without excessive feedback, it is clear that the M10 performs very well in other systems with different speakers (i.e. Magico, Goebel). The "mismatch" hypothesis was confirmed by the simple fact that the Parasound JC1+ drove the Alexx V bass to the point of ecstacy, so it didn't take being a rocket scientist to figure out that the limiting variable was the speaker load itself. Coupled with the fact that I watched the M10's flash 1+ KW a few times, my power demands eliminated many potential suitors. To be honest, the amplifier I would have loved to try is the Constellation Hercules II. My thought was that if John Curl could do what he did with the JC1+, I could only imagine what he could do building a cost no object amp such as the Hercules II (at 10X the price of the JC1+). I'll bet it would really be something to hear. Unfortunately, they are as rare as hen's teeth to hear in a good set-up, nor did I know a dealer that allowed me to explore their potential acquisition. The Gryphon was attractive because it provided the confidence that it could drive the crap out of anything it was connected to, and had a formidable reputation universally as an excellent sounding amplifier. In addition, it offered a design approach that was intriguing, which is namely, that it is a true Class A amplification device. I remembered years ago living with the Pass Aleph amps. I enjoyed something about their sound that was very appealing. But the Alephs were low powered units (40W). I always wondered what a no compromise, high powered Class A amp would sound like in my system. I guess I'm about to find out. In addition , Elliot facilitated a very workable deal which made the logistics easy, with the only exception being he did not provide the two NFL linebackers I had to hire to move the damn things into my room. Each Mephisto Solo is a 240 lb. beast.
I can't talk about sonics now as it's never useful to discuss this until break-in has occurred. All I will say is that the initial session last night was promising. However, it is noteworthy to say that the Mephistos are not just amplifiers. They are also room heaters. This can't be overstated. Frankly, they put out so much heat that most people will simply not be able to keep them in their listening room and be comfortable without air-conditioning, even in the winter. Fortunately, my amps are located in a room immediately behind the main listening room so that's not an issue for me. Plus, it provides a double benefit. With some new wooden benches, I can now use that room as a sauna. And of course, you can literally fry an egg on them. Breakfast in the sauna after a late night listening session, anyone? Come on by! Ah, the joys of owning high end gear.....
