Well, i have found a suspect for the part of acting Power amp in my system.
I have been using a couple of InterM R500Plus amps to great effect, they are truly amazing for their cost.
But now my local dealer had something exciting on his hands and and the price was reasonable.
So i asked politely for a loan and it looks very much like it's staying:
Karan KAS 180 Power amplifier
Sorry, no full pics at the moment...
It is, as usual, fed signal from my pre/streamer/dac:
Bladelius Embla DL Classic
or possibly from this (at the moment)
Michell TecnoDec with RB250/Technoweight and a Benz Micro Glider L2
To my ears the Karan plays Music in the most convincible way i have Heard in my system. I still kept what i liked about the InterM's, a powerful punch in the lower mid/bass section with great dynamic headroom. The Karan does play voices and top in the most silky smooth way you can imagine, without ever masking detail. It didnt change the tonal character of my whole system, just let the Hifi shine through, depth, soundstage, microdynamics etc.
Some call the Karan sound Tube-like, but im not sure i would agree fully. Maybe in the very smooth mids och voice registers, but tha bass is way better than i have Heard from tubes in my home. (TBH that is not so very many)
Looks like we have a Winner!
