I recently purchased an ALK Universal XO built by DeanG off of the garage sale. I've always been interested in trying some out and when they came up for sale I figured, why not.
They were installed in my '77 LSI's in the early AM this morning. After 6 hours of listening so far we all agree (myself, wife and kids) that we much prefer the original recapped AA's. What we're hearing is instruments are being pushed WAY back, especially guitar riffs when singing is involved. I'm not sure that I would call it anemic but definitely not what I expected. I've rechecked all connections and everything is right and tight and positive and negatives leads are correct.
Favorite music that's been played today includes AC/DC, Joe Bonamassa, Dusty Springfield, Etta James, Jeff Healey, Samantha Fish, King Crimson, you get the idea.
I'm using the same setup that has changed very little since I inherited the LSI's back in 2016 and includes a dual mono SET amp from forum member Maynard, tubefanatic, being fed by a SONOS ZP90 running through a Schiit multibit DAC so differences in are readily apparent.
The tap being as used is tap #6.
I'm wondering if anyone with any experience with these XO's has any helpful advice or if this is an expected difference between the AA and ALK Universal?
Thanks for any and all replies!
