"However, where the quad really falls down is with dynamics. It just doesn't have the sheer punch that the CLX does."
Personally, I think this is an area the in which CLX does not excel. It presents things in a very relaxed, laid back manner. It has a very "full" presentation, like it doesn't need a sub, and never will do. But critically, you could acuse it of being a bit thick sounding, as if there is a bit too much "richness" in it's sound. A bit like "I can't reach to low, so I'll make t sound good by being generous elsewhere". And, of course, it doesn't reach that low, and yes, if you want to hear what is going on down there, you will need to supplement it with a Descent i or two.
However, this is a much better presentation than most ever achieve by a long way. I am reminded of Linn in their great days, with a Linn Sondek LP12, Ekos, Karma driving Isobariks via, I think if I remember correctly, LK series amps. This had that sort of upper bass bloom that is very attractive and pleasing to the ear, just like the CLX driven by Jadis JA200 amps.
The CLX soundstage is absolutely vast, and very convincing. For this aspect alone, it destroys most of what is available, at any price. In this sense, it is actually remarkably good value.
I'd like to hear the CLX driven by some high power solid state gear. Specifically, when heard with the Avalon Eidelon's, the CJ is a very "head together" amp, but not a very adventurous one i.e. it doesn't take many risks and is very polite and hard to find fault with.
I personally think ARCs would be the best drivers, though. Their amps have a kind of "get more real than this" feel to them. I have had many years break from hearing a great ARC based system. And it would be a breath of fresh air to hear something as good as the V140s were in their heyday. The best compromise between solid state and transistors I have ever heard. Brilliant amp. A++ rated in my book. If you can pick one up second hand, you will be far from disappointed. Even in the year 2008.
But that is the past, and this is the present. And in that respect, the CLX gets my vote. As a clear winner? Yeah, sure...
