Ultrabit Disc treatment

Ozzy,
A couple of different questions for you to still further help in my questioning;
Did you also have to use the disc cleaner prior to using the UltraBit?
Also my musical tastes are in soft rock(some harder), blues and jazz, if using UltraBit would (IYHO) still make a difference that would warrant the price? My system is "compact" using a Classe Integrated and AR CD2 thru Apogee spkrs. I also use the phenonimal Marigo 3-D stabilizer (which works Excellent!) with my rig and vib controls. You can see why I ask and why I still have some skepticism as well but, I much appreciate all the info you can help me with.

Ozzy & Atrhursmuck, I'm still doing (some more) research on Ultrabit but, I took the time to review the systems that you are using to help me compare some of my differences and let me say WOW!!!! I've got what I call a compact but nicely reveiling system. You both have great tastes in your choices (sorry to get off track). If (and when) I get Ultrabit, the 1st disc to listen to is Red Rider Neruda it has some low level voiceing and back grounds that I can only hear loud (I listen at VERY MODERATE volume levels) or very near the speaker, a good challange to hear a difference. Alternately have you listened to (new) CDs before that only got better sounding the more you listened to them without ever doing anything to the disc itself? I have had this happen example; INXS Switch.
Even my daughter listened to it with me and commented the same things, very veiled and compressed sounding, after 5 listens I had her listen again she asked if it was a different copy becuse it had opened up so much and sounded totally different! Not the first time it's happen but have you any speculations as to why? Thanks for your input so far, it has helped :)
