Rotel RHB-10 : New life of my "Michi Kokoro"

Martynka · 2023-01-31T16:04:55+00:00

Hi, I like hard and heavy speakers, I had in my system many of big Infinity like RS2.5, RS2B, Kappa 9, Kappa 8, Kappa 7, Re90 and many other. Now I have first Martin CLS with first "crossover". All of this speakers need strong power supply, all eats ampers. I had tried Yamas like old M2, biamped M4 strongest MX10000, Krell's, Accupase's, Nakamichi.... and more. Now I discovered this: Rotel RHB-10... it's Rotel only in name, inside no budget construction, zero compromises, zero "steryle sounds" like from Rotel. I bought it for try. I need something strong to play with my hungry for current CLS. First I opened it: Really good construction, full dual mono, two 1kVA transformers, two PCBs with rectifier circuits, capacitors in all circuits are oversized NIchicon GreatSupply and Rubycon BlackGate, good copper grounds. I check DC-offset and regulated bias and connected to my system. Sounds in "Japan style", high tones and mids were great with little leak of bass. It's completely opposite my Krell but if you have electrostatic or ribbon speaker high and mids are like miracle and you need more and more. I decide to use "Michi Kokoro" in my main system.... ... but like all my parts in perfect conditions: I dissasembly power amplifier and decide to change all caps, maybe about BG I will decide after measure with RLC bridge

Hi there, hi Martynka,

Great work and thank you for sharing it. You wrote that you exchanged all caps. What models/manufacturer did you go for? Do you have by incidence an orderlist? Need to do the same...

Thank you!
