Loving the sound of the V7 Classic Op Amps & plan to try the Burson V7 Vivid Pro before deciding which to replace the Sparkos.

Please tell your web master to NOT wipe out all of the input in this form when someone accidentally skips the Category field. I had to reenter everything and repost pictures.. annoying
