The new 6-Channal Milq is up and running, I did manage to calibrate everything in the Macondo’s left channel and was listening it for a while. I might report somehow a controversial result. The MF drive with a single stage is incontestable king – it very clean and it cured the S2 from all its illnesses. Should I rejoice? Well, not real. Along with a phenomenal smoothness and cleanness the MF now exhibits a behavior that I do not like, in fact - hate. That all makes the enter sound absolutely not acceptable. Here is what I found very wrong:
1) With increased of dynamic the channel go thinner, the higher volume the thinner it goes. Extremely ugly!!!
2) The channel now too fast, inappropriately fast, faster then the rest of my channel. It is a way hyper-transient and harmonically deficient – a typically overly idling tube
3) It sounds OK power vise only with full 8-9W dissipation on the tube – a very full power. Lowering power to 6W and the channel begin to loose in stresses.
Here are possible solutions that I am considering:
1) Heavier loading the tube that should eat some transients and add power.
2) Trying a different output transformer if it will not help
3) Change, S2’s impedance curve after 10K
4) Accept that a single stage amp was a dad idea.
Frankly I do not case about the wrong transient and harmonic balance - I will be able to deal with it by loading the tube it will also shell address the problem with power. However, I am VERY concerned about the increase of thinness with rise volume… I afraid that it might be a characteristic of a sing-stage amp… I play that the effect will go away what I load the 6E5P much heavier.Rgs, Romy
