    Anyone reckon the Pass amp would work well with a pair of 705’s? Or perhaps as monoblocks, which apparently is a build option? Thanks.

    Ehhh.... I'd pass...... the 705's need a decent amount of wattage and current, and the pass aren't built to do either of those to the scale you'd need.

    The ACAs need some decently high sensitivity speakers. Otherwise, you are going to miss a LOT on the low end and things are going to sound sloppy.

    Performance-wise, the original morph of the ACA isn't all that dissimilar to a single-ended 2A3 amplifier -- albeit a bit more powerful and probably wider flat response compared to any even marginally affordable 2A3 stereo amp.

    So... think SET/fleapower friendly loudspeakers.

    Vintage Altec, JBL or (shudder) Klipsch fills the bill nicely (e.g.).

    So 'Doc' I can't believe no one has asked you about this after all these years. Why didn't you paint or ,stain those speakers. They stand out like very sor thumbs and need some beautification. Being an old Yankee you must have some Marine varnish up there so throw some coats on. and counter sink those screws. Chemistry and radionics are your strong suit but not to much on the the aesthetic. Look who's the critic now ....lol

    He's a "form" over function kinda guy DUH!

    Also with as much as he's tweaked them over the years at times (adding in super tweeters, other horns, etc) at the top of them it wouldnt make sense IMHO to finish them.

    The answer is supremely simple. I could only make them look worse if I tried to finish them.
