I posted on audioasylum regarding the output impedence of the aca2b. It sounds as though the spec of 50,000 is unusual and may be a misprint unless it is a passive preamp. Perhaps mbarnes can confirm this spec. I'm mainly concerned because I would like to use an aca2b and 2 leamp2's with 10 foot innerconnects and do not want to find out the hard way that this will not work. From what I have read, right or wrong, it sounds like you could potentially loose high frequencies with such a setup.
Thanks for any response.
