Okay, maybe stunning may be an overstatement, but this one stunned me because it was unexpected. Also presents me with a dillema (sp?) for some of you wire experts out there. I had to move my system, which consists of recently upgraded AVA T7 (with tesla tubes and new transformer) and my recently upgraded (new tubes, blah, blah), and as a result, had to disconnect my IC's. Before I go any further, let me say thanks to Tyson and Cutthroat for recommending the upgrades. The older AVA stuff was very nice...so nice, many people are sick of hearing me talk/write about it, including my wife...especially my wife.
Frank and Co. did all of the electronic upgrades within a week (including cleaning all switches, swapping those irritating little star-head screws for good ol' fashion philips heads and changing the feet!) and packed the stuff up in brand spankin' new boxes (much better than my "improvised" boxes that barely made it to Minn...). The upgrade was a noticeable improvement from the first note (I let things warm up for about fifteen minutes prior to listening). Everything that I liked about the old Fetvalve stuff, I love about the new T7 and 550EX. The improvements to the phono preamp and headphone amp were also immediately obvious. I'll do a more detailed summary when I have other amps in-house to compare the AVA gear with. That's something I'll save for the colder weather....
Anyway, when I put the IC's back in the system, I accidentally put the DIYcable superlative IC's between the amp and preamp and the Bolder M80's between the DAC (Smart Dio) and the preamp. At first I wasn't paying attention and didn't fire up the system, however after a day or two (I was traveling on business), I put on a CD that I hadn't listened to on my main system, Aimee Mann's Lost in Space. Bass sounded really "big" like the bass on a tube amp and everything sounded very smooth but slightly rolled-off. At first I thought it was the recording. I really liked the bass (the Ellis 1801's are not known for deep, sub 40hz bass). In fact, it was the strongest bass I have ever experienced with my speakers. Those of you who are in to tube amps know what I'm talking about. Bass was very deep (for a 6.5 inch woofer) and LARGE sounding. I quickly put on some jazz CD's, ones that I was very familiar with. Again, very deep and LARGE sounding bass. Acoustic bass in Kind of Blue sounded full-bodied and authoritative, however vocals sounded a bit recessed and further back into the mix. Instruments blended together a bit more than I'm used to and, for a moment, I thought something was wrong with my system.
I looked at the wires and noticed that I accidentally swapped the M80's from their usual position (between the amp and pre) for the Superlatives, which are usually between the DAC and pre. The difference was significant, however, I really thought I was missing much of the transparency, detail and depth of the older setup. I swapped the IC's back to their original position and...voila!!! Everything snapped back in to place. The "air" between instruments was back, detail was there (in spades) and vocals were perfectly out in front of the mix (not too much!), the way I like it. Unfortunately, all of these improvements came at the expense of the bass I was getting with the older wires.
This leads me to a question for all of the wire guru's out there: is there an IC that provides the positive characteristics of both of these fine IC's? I want the detail and transparency of the M80's with the forgiving nature and strong bass of the Superlatives. I tried M80's (and ones with silver Eichmann's) between the DAC and the Pre and preferred the Superlatives in this position. Are there any IC's that provide stronger (yet controlled) bass of the Superlatives, while prividing the positive aspects of the M80's???
Thanks!

PS-I may hold off any wire auditions until I try the dAck. Danny's review has me thinking. The only thing preventing me from getting the dAck outright is the limited play-time. I have parties at my house and need music playing at all times (while I work, etc.). Can't live with 4 hour limit...8 hour limit maybe...
