… and it is very important do not overlook this difference. Multiamping is fine but is it severely suffer in case of different amplifiers were used. Preaty much a multiamping where each amp has own TTH characteristic is assurance of crap overall sound. How to maintain the same TTH balance across all amplification channels?  If I was a knowledgeable amplifier designer then I might answer this question or would feel that I could answer but it is not who I am. To me the TTH equilibrium is more an empirical and not necessary predictable thing (though within a certain scale I can manage it). So to be in the save side I do not necessarily advocate multiamping but rather DSET.

Multiamping is using of dedicated amps for different channels. DSET is the use two or more of the SAME AMPLIFIERS (SETs in the given case) optimized for a given frequency range (output transformer in case of DSET). Here is the illustration: 3-channal Super Melquiades was a pure DSET with 3 6E5P-6C33C parallel channels. The late 6-channal Super Melquiades with it’s single-stage amps is a deviation from the DSET evangelism and it is more multiamping. We can make some excuses that the Sound of Milq is not determined by out stage and many other excuses but realty it that it is still not DSET but multiamping. I did spent a substantial amount of efforts and time (~3 month) to make sure that that way how I use the Super Milq channels do not break (or “almost” do not break) the TTH weighing scale but the 6-way Super Milq success is still arguable.

In case of pure DSET – where each channel is IDENTICAL there are many problems not there anymore and with an identical loading of the plates via different transformer of the same type a user is in a very “save” environment.
