Hi Lawrence!
Believe it or not, it's all specific to your needs.
Mikey and I have been sharing ideas and tech for a few years--
he has been so kind as to wind some things for me that no one,
including Mike really thought made total sense. Mike is brilliant
and thinks along with the user, and can get things made that are way
out there-- if needed.
You might say the gentleman let me have what I wanted-- within
practical limitations, of course.
Toroidals are good for total efficiency and bandwidth, but do have
some overlay/winding issues that you may or may not wish to listen to.
The best push/pulls I've listened to had toroidals. It's possibly
the ability of a p/p circuit to cancel-out some distortions that allow
good overall performance at the speaker. With SET, not always so much so.
I have some "R" cores in stock, and am evaluating them. I started with 10 units-- we'll see if I continue with them. So far, (this is a SET)
Highs have been stellar-- very extended and very low distortion. Midrange
rivals my custom Maggies, bottom end is clean, but not as extended as
with the Maggies. More break-in is required on the test amps before I
will know anything. I evaluate transformers normally at 1000, 1600, and 2500 hour points.
This is accumulated time, not continuous operation. Leaving an amp
running doesn't offer good break-in. On and off cycles DO, but run times should be an hour or more-- best is 4 hour runs, playing everything you like at normal levels, and louder as you desire.
These are just general observations and cannot be considered Gospel.
My take on your post is that one can get a great output transformer in any of these build methods. It depends much more on who winds it, and what
his standards and materials are.
Denver's coming up on Oct. 6, 7, and 8, so I'm going to be less on
here. RMAF 2017 looks like fun, so I will do it in Room 3017.
See 'ya, Lawrence!
