Jeff Rowland Concerto or Simaudio i7 integrated?

Thanks again for your inputs.
I finally settled on something totally different. From T+A (Theory + Applications); a German firm.
Integrated: http://www.taelektroakustik.de/eng/ta2/r_system/pa_1230_r.htm
CD: http://www.taelektroakustik.de/eng/ta2/r_system/sacd_1245_r.htm
I got the CD player as a demo and bought the amp new.
Very fast, wide-bandwidth components. Neutral and very detailed (but not harsh) sound. Extremely well designed; compact yet very powerful. With my Tylers, they make for an incredible system.

Which amp did you get? I am looking for an integrated and they show 2 of them, 1230 & 1530.

If you click on the link (integrated), it will bring you to the page describing the 1230. I bought the PA1230 (100 watts/channel). More than enough. I was very tempted by the 1530 (150 watts/channel), but it was beyond my budget.
