I could never reccomend AV123 or the RS1000's either. I tried them in my system and the crossover in both speakers went out in less than 10 minutes. I Plugged the old paradigm monitor 11's back in and no problems. In short, I upgraded to Paradigm studio 100 V4s.
AV123 gave me a "partial" refund, even though they admittedly sent defective gear after weeks and weeks of headaches and 1/2 truths in emails and dodging phone calls.
All in all this experience was a blessing! The Studio 100's are amazing speakers, not weak, recessed, or veiled. They are extraordinarly punchy with excellent impact, clarity, and great low end. They match well with with an svs 13 ultra sub and xpa-5. In essence I can't say Im upset about being burned by AV123 as I TRULY ended up with a FAR superior speaker, reliability, and in my opinion, superior sound!...which is the most important to me. There are many reasons why people love Studio 100's. I say give them a listen. They are incredible! Used and floor model prices are in line. I picked up demo's of the 100's and cc690 center for a little over 2 grand in Pristine condition in rosenut. Check out Audiogon and vidiogon as well for the 4 series as the 5's are now out.
