Home Amp/Preamp Asylum

a discovery made with Harmonix RF-57 tuning disks

today I opened up the top of the Bel Canto Evo4. Placed 2 RF-57 tuning things on each Tripath chip, one at either end, one on the input board, and one where the ribbon connector links the input board to the motherboard. 8 (one pack) of the Combak RF-57 were applied. Nothing else touched. As the amp warmed up again and I played some music, I started to notice how much more natural and organic it sounded. Closer to "good analog", i.e. real expensive, heavy, upmarket amplification.

I honestly think the Harmonix people are on to something with their resonant tuning ideas. I do notice that their Reimyo (sp?) line of electronics receives the highest praise. They're doing something right.

Well known music that I have heard through dealer systems, my older systems, yadda yadda, took on a new life, like Mambo Sinuendo that always sounded a bit cramped and flat just expanded and filled the room, or Grant Green's Carrying On.... Green's guitar just dug in, the emotionality poured through....

Very subtle resonance control appears to be a SIGNIFICANT factor here. I did hear the Evo raw, had some initial misgivings, we tried a heavy damper on top, made it fuller and less bright, but no Eros.

Harmonix tuning makes the sound Erotic in the best sense of the word.
