Mike uses the VSF copper in his top of the line speakers such as the ML1's I got out to you. I think the wholesale price alone of the capacitors in the ML1's is about $500.00 per speaker ie $1000.00. The ML3's References have about $3.5K wholesale worth of Duelund capacitors in them alone. With Mikes Reference speakers, while not cheap, being about the same price as other high quality manufacturers like Aether Audio, you certainly know where the money goes.
Of course Mike makes speakers without Duelunds and they are quite a bit cheaper. Trouble is once you hear Duelunds you don't want to go back - but the cost ouch. That's why the ML2's I am looking to get out to you is not the Reference with all Duelunds but a version of the Plus R's with Duelunds as bypass. You get 90% of the performance at a much cheaper price. My ML3's that will be coming out will be the version with all Duelunds because that's what I purchased.
Thanks
Bill
