I burned these in for several days then did some listening test on them yesterday.
I was very impressed with how these speakers responded to the upgrades. These are now very good sounding speakers.
I made some A/B comparisons to some old A/V-1's that I had still in stock. They are now a real similar speaker. Woofer wise I wouldn't trade the Elac woofer for the M-130 used in the A/V-1, but the difference between the two was pretty minor. The Elac woofer sounded really good. Too good really for no more than these things cost. And now lined with No Rez the bass response is nice and clean with no more residual buzz.
In the top end I began to think, the more I listened, that the Elac actually sounded a little cleaner in the highs. This perplexed me a little as the tweeters are similarly made with no real advantage to the Elac tweeter. Both were using Sonicaps too. But the old A/V-1's were built long before tube connectors came along. I know the tube connectors are an advantage, but could they be doing that much I wondered? So I moved the speaker cables from the tube connectors to the binding posts on the back of the Elac's and the advantage that the Elac's had in the upper ranges and better clarity went away. They then sounded pretty equal to the A/V-1's. And that is still quite a compliment to the Elac's. After that I really wanted to go through all of my older demo speakers and upgrade them with tube connectors. Those tube connectors rule!
No more rolled off top end now either. It sounds very extended and balanced. And not even a hint of brightness or aggressiveness in the top end. They still sound really smooth. Imaging is really good as well.
The mods really transformed them. I'd feel real good about putting these up against any mini-monitor and I think they will really beat up on most of the mini-monitors in the $2,000 and under range.
