Mo the stage pass is a more powerful unit w/sm/mixer.....remember what I said in my review for the power & size the CM30 its is excellent sounding for the right SMALL gigs...if your doing bigger jobs then of course a bigger PA is required.....why not check out the Mackie SRM350's also for smaller lighter sound PA reinforcement ?

BTW I hear & played thru the Traynor K4...
its very ergonomically manageable for sure & flexibly designed to cover a full array of situations, best ONE Piece unit for Kb/Voc I have heard....check one out for sure!
