Hard to see how this unit is any way frivolous. Looks like a solid, no-frills class AB design and a pretty good value. I won't name the mfr. as it is still in business and this isn't exactly the most flattering venue for it to turn up in a google search.
I don't mean it was frivolous. I will stress, unlike some boutique woo-woo amplifiers (eg. the humming VTL the KEF distributor here demo'd the LS50 passive to me with... he said he couldn't hear any humming), it was nothing less than rock-solid, quiet, cool-running and simple. I only put it here because of the concessions made to really fancy boutique parts. This does not detract from how good a value it is relative to the parts used, the great customer service and the performance. It is however, no nCore.
