Has anyone done any worthwile tweaks to their...

Agree...I wouldnt get too carried with mods to the Swifts...they are only going to lessen their resale value if you ever upgrade...and adding felt around the tweeters is largely a myth...true..Spica tc-50s used felt...but their spacious sound was more due to internal componets than external..cheers..however...if you are dead set on upgrading...call Meadowlark and get it done in a professional manner...the Swifts are not speakers to start out modifying if you have never done it before...

Hi,
Thanks all. Basically what I'm trying to accomplish is just a litle more transparency, and a more three dimensional soundstage. I want instruments to have a little more roundness and solidity to them. I currently have a pair of IRD Audio monoblocks, AMC CD8B cd player, Music Angel tube preamp, Mapleshade Golden Helix speaker cable, and Belden interconnects. Thanks again.

Lord..sounds like "tube" power might be your ticket..
