I wanted to thank everyone for their input. What I find most surprising is how many of the suggested songs I already own in one format or another. Collectively you've given me a LOT of "critical" listening to do. Thanks again. Now... Where did i put that Police album...

I'm not quite sure where to put this. If the mods feel like this thread belongs in another area please feel free to move it. The question is: What is the very first thing you play after making a change? Your "reference" song. The piece of music that you know so well that it immediately shows the effect of whatever you changed good or bad. Myself... It's Tocatta from the DVD-A of ELP's Brain Salad Surgery. That album is one of a dozen or so that I own on CD, DVD-A (or SACD) and vinyl so I get to hear a couple of different mixes. No matter what the source is I've yet to find another piece of music that will give a set of speakers the workout that Tocatta will. Enlighten me... Please!

Well I just finished the crossover rebuilds. What a change!!! I guess the 31 year old caps had seen a better day I'm going to let them play for a few days while I'm at work just in case there's something to the whole "burn-in / break-in" thing. I do think I'll end up swapping the K-77-Ms out of the Heresys for the K-77s currently in the Cornwalls. From what I read the "Ms" have about 4K better range then the originals. Not like my 51 year old (concert trashed) ears could actually hear the difference but my 51 year old (beer soaked) brain is telling me they'll be "better". Anyway... Much much thanks to Bob Crites for supplying the various bits and pieces so quickly. Now... Back to the music. Next up... A little Pink Floyd... I'm feeling a little Dark Side of the Moon (SACD) in my immediate future. Good night all...

This past weekend I picked up a pair of CWO Cornwalls from a local estate sale. They're not "mint" but they're very very nice especially considering they set me back 5 Benjamins. They're "S" vintage (1978 I think) and bone stock, They're not consecutive serial numbers but only 3 apart. Considering the effect that recapping had on my 83 Heresys I've already ordered the kit from Bob Krites. Those will go in later this week. If they make as much difference as they did on the Heresys I'll be in audio heaven. Don't get me wrong here. I'm very very pleased with the way they sound. I just think that they have a bit more to give if massaged just the right way. I especially like not having to fire up the subwoofer [] OK... On to the questions... 1) I want to replace the backs with 3/4 MDF. Why? Well I want to change the terminal strips to binding posts that will accomodate my speaker wires (12G Tributaries) and their somewhat large spade connectors. The question is: what's a suitable replacement for the damping material fastened to the existing back? I have no interest in disturbing the existing material as I want to able to put the original backs away in case I ever need to return them to "stock" condition. 2) I could be wrong but my ears are telling me that my Heresys have better high frequency extension. There just seems to be a little more "air" there. Bells are clearer, cymbals are crisper, etc.. The Heresys have K-77Ms (square magnet) HF horns and the Cornwalls have K-77 (round alnico? magnets) HF horns. As the Heresys have been relegated to "surround" duty is there any reason to not swap the tweeters? I do plan to install Crites CT125s in both the Heresys and the Cornwalls when budget allows but I'm thinking that swapping them might just satisfy (yea... right) me in the mean time. Thoughts? 3) Until I can put together my ultimate "vintage" 2 channel system I'm using a fairly nice Yamaha receiver at the head end. In that my listening area will only accomodate a 5.1 system I have a couple of "unused" channels on the receiver and it does support bi-amping". The crossover circuit looks to be simple enough to break out the woofer from the squawker/tweeter circuit allowing them to be bi-amped. Has anyone done this? What were the results? Is it worth the trouble? Thanks in advance for what I'm certain are going to be a pile of well considered answers and spot on guidance.
