Dear friends: This is another example of the " black magic " between the tonearm/cartridge combo:
in the past, I buy two tonearms MDC-800 from Sumiko ( The Arm ) that I never mounted. A few months ago I put on sale one of them ( I think for 800.00 dls here in Audiogon ) and in the first ad day I have 15 persons heavy intersted on buying this tonearm ( inclusive, I receive a 1,100.00 offer for it. ), it sold that first day ( unfortunatelly for me ). My idea was two put on sale both but after the people reaction I ask me why everyone wants this tonearm, so I mount for the first time in my system.
I try with the Denon DS-1 and with the Sumiko Celebration ( I can't mate with heavy weight cartridges because I have only the low weight counterweigt on the tonearm ) and both cartridges sound exellent. At that time my Colibri ( the 2.5gr version ) was on the Breuer 8 and sounding really good. I take the Colibri from the Breuer and mate with the MDC-800 and now the sound not only is a very good one but an exeptional one ( My Colibri and my MDC-800 born to be together for ever. ).
The MDC-800 is an exellent tonearm copy from the Breuer in any single parameter but the internal wires, and it hands down the Breuer ( at least with my Colibri ), the Breuer is one of the best tonearms ( for many people is the best ) ever made. BTW, I already sold the Breuer and take this money to buy another tonearm and cartridge.
Regards and enjoy the music.
Raul.
