Setup and install went smoothly once you get used to balancing the feet cones on their supports. Do not leave the cone support pads out of your setup - if you are putting this unit on anything softer than the metal cones you'll be left with large indents after a very short time.

Solely based on the 700i's "Moon" product family I decided to give a homonymous fellow a shot for some listening. I actually hadn't listened to this one in a long while so I was struck by the inherent noise floor in the recording itself. Sometimes I appreciate a bit of stadium/studio noise or analogue hiss for the atmosphere it adds but in this case it had me scrounging around for cleaner recording to "enjoy the silence". That being said you could hear every string reverberation on the lead guitar during Pinball Wizard. The soundstage is as natural as this recording is likely to get given the nature of the recording ("lead guitar – thou shall appear in the left channel and left channel only) for this album but the vocals were centered and the soundstage depth was wonderful. Moon's (the drummer not the amp) intro ride cymbal shimmers in front of you on "Underture" and the transients from the snare and (endless?) toms were crisp. The mic positioning for this song must have been interesting because it feels like you were there drumming along with Keith.
As a side note, after spending some time with the 700i I had noticed a small hum centered around 5kHz had developed that I could not escape. It was only about 15dB above the ambient background but was noticeable both in standby and in use. After much troubleshooting and isolating of components and some discussion with Simaudio we swapped out the unit. The issue has not re-occurred with my second 700i nor were Simaudio able to re-create the issue back at their facility.

During the first Allegro movement of the Suite in F Major the pounding harpsichords were quite detailed and almost "in your face" in terms of presence. The Hornpipe in the G Major Suite was it's usual celebratory self and the fact that this performance is made on period instruments comes through in the depth and timbre of the sound. This piece must have knocked the King's socks off the time it was first performed as the popular music of its day.
I listened to many other tracks during my testing and never found the amp drawing much attention to itself. No clipping no matter how loud I turned it up, no distortion, just music. The only times I noticed it doing it's thing was during high current demand music passages with sharp transitions as well as the overall clarity and resolution along with the noise floor via the balanced inputs. Having the dedicated clean power available makes a difference vs. my usual more HT oriented setup.
