Levinson gear has only been available sporadically here and never had an importer who did a particularly good job.
I'm of mixed opinion about him and his products. First, the man was a marketeer, but I can appreciate his 'vision' and his goals. That is, a desire to build the best, cost being no object. Obviously there is always excess in that sort of endeavor, and excess will always turn some people off.
From what I've read, Mark's customer support was always first rate when he was at the helm. Not an engineer, he hired competent designers (John Curl, Tom Colangelo, Dick Burwen). He was not afraid to buck trends (his embrace of equalization--the Cello Audio Palette), and in fact created trends (his movement away from flimsy RCA connectors, mono block layouts for both amp and preamp circuitry, high current capability into low loads, the importance of adequate power supplies).
At the same time, he couldn't tell you why his preamp 'sounded' better than anything else. All that was built on an edifice of sham. But he wasn't alone in that, for sure. Almost everyone believed in it, back then. From that historical standpoint, David Hafler was more 'right' than Mark. But in long term 'value'? An LNP-2 is probably more likely to be working at spec today, than the switches on a PAT-5 which have long since corroded away.
The question one has to ask is whether any of it (other than equalization) made any difference in sonics? The answer is clear. In fact, in the case of his ML-2 amp, its lack of voltage could be a huge limiting factor in sonics, depending.
A man who owned his gear (ML-6a preamps, ML-2 amps, Mark's modified Studer A-80) told me that if he matched levels and hid the brands he couldn't tell a difference between it, and any other decently designed gear. That said, he told me he'd rather own ML items for long term reliability and aesthetics.
In this particular instance, that is, the 5302 amp...? Why anyone would buy it over a Benchmark would be a mystery to me. But if one needs more power than that, into low impedance loads, the bigger Levinson amps might be a starting point to consider. But there are a lot of other choices, too.
