I do check into Jeff's place a fair bit. Excellent site!
We both have horn speakers and 3 or 4 years ago on here I was asking Duelund to build autoformers and Jeff had them made for him. Which I was glad to hear! (and envious!)
I have mentioned in the past wanting to hear Western Electric caps to compare to Duelund. (I have not) A best of the past vs. best of today kind of thing.
My favourite amp is a 7591 style amp like the one Jeff uses. That amp was left all stock and my work was done on EL84 amps until firmly past the vintage 7591.
I was surprised Jeff (another big Duelund fan) used Teflon wrapped wire? (not all natural like cotton or Silk)
I am glad to hear he has compared to a cotton wrapped Western Electric which did not surprise me at all he would like better than Teflon wrapped.
I use Duelund Silver 2.0 which I really like but have not compared to copper Western Electric. (which I could use no matter what in office system over plastic wrapped wire I have now)
My whole top amp is Duelund caps except Jupiter in phono stage. (room reasons)
I bet it is a matter of time before Jeff mods his MacIntosh amps. I purposely bought amps at the start of this thread that were not hugely collectible so that when modded I was not destroying resale value.
I can say it is a jaw dropping improvement from vintage caps to Duelund. In my amp I have VSF, CAST and RS and all are good!
I just want one of those Duelund Autoformers like Jeff has just too much form me at this time. Then I will have no vintage parts left in the crossover!
Has anyone compared though directly Duelund Silver 2.0 to Western Electric. (which is MUCH cheaper!)
