Yes, thanks Charles and thanks for everyone who sent the direct amps on this subject.
The ClarityCaps, similar to the Canadian Solens, British Ansars Supersound, the French MKP, and a few others proposed, are all Metallized Polypropylene caps. I am not a big fan of them generally. There are also an Oil-Impregnated Metallized Polypropylene caps like Siemens/EPCOS MKV, V-Cap, Vishay, ASC, GE, Sprague and a few others – the motor’s start up caps - I am not a huge fun of them ether. I did not try all of the in PS but I did play a lot with Metallized Polypropylene on speakers and in line-level coupling application and I did not like the results. So, I have large 100uF Ansars that I will use for now but I will keep my eye open for more “intellectually interesting cap”.
Also, I reach a pathetic point of my live when I decided to build a new PS for my amps and… and … and … and I accidently have all parts that I need right in my home – very troublesome symptom. So, the PS will be a 300mA torpid with 220V secondary, Schottky full-wave bridge, inputs choke 15H/150mA and 40mF and then RC with 100uF. I should be arriving at 200V, 110mA of 3x6E5P and most likely I will bleed extra 20-30mA through the choke – I do not know exactly now – I will measure the choke performance when I build it.

Hm, interesting. I remember a long time ago I did tried to detect the sonic influence of ferrite beads on my 7788-7721 phonostage. At that time I was listing the 7788 with and with the ferrite beads and I did not detect any sonic impact. I did it only once and never thought about it again. I never tried in with Melquiades. I do not know who CH is but I do like the Ayre as a company, so I presume that whoever CH is he is not an idiot. Still, if CH is correct and the ferrite bead gets magnetized with time (it is not difficult to measure with a gausemeter) then why should it affect sound? I really do not know the answer. It would be a good idea to remove the long-worked ferrite beads and to listen if the sound was changed. Unfortunately in my case if the ferrite bead was working for a long time then to physically access to it in the Milq would require an archeological expedition…The Cat
