Just thought I would offer my 2 cents.
I purchased an original ZP80 and ZP100 many years ago and I absolutly love them. That ZP100 digital class D amplifier is nothing short of amazing. I used that amp to connect a Cowen A2 music player via analog in and supply a pair of Energy Veritas 2.3 tower speakers, plus a pair of Energy Pro 2.5 bookshelves and a 12 inch sub to very high levels while jaming with a full band (I'm the bass player) for over 8 hours straight.. it never complained, never shut down, never clipped. By comparison, my Adcom GFA1400 125W RMS amplifier shutdown 4 times due to overheating during the next jam session driving the same speaker setup. I cannot say enough good things about that ZP100.. now in my opinion, the ZP120 is nowhere near as solid, even if it's 5watts more powerful, I think the smaller form factor definitively took a lot of bite out of the original. I use the ZP120 for my outdoor speakers during the summer, and my ZP100 for my better setup in the kitchen.
Having said all that, and I know some will not agree with me, but an external DAC can make a difference, providing the rest of the gear is of adequate level. My experience was that the internal DAC of my Blu Ray player (Panasonic DMP BDT-350 retail for $300) playing a redbook CD sounded BETTER than my $5000 Anthem AVM-20 Pre Pro with it's internal AKM DACs playing a Flac file VIA the Sonos ZP80. This was disconcerting, therefore I embarked on a 2 year journey to acquire an external DAC that would remedy the situation and eventually I did achieve my goal. About 6 months ago I purchased an Anedio D2 DAC, which made an immediate and positive improvement in my listening pleasure. This DAC sounds better than my BD player and my Pre-Pro, to MY ears.
I have sinced upgraded my interconnect cables between the DAC and the pre-pro to balanced Kimber Kable Hero and my flac files residing on my NAS fed via my ZP80 to my Anedio D2 sound quite amazing indeed.
And before anyone slams me for even talking about cables, for the longest time I truly believed that a decent cable was more than adequate and that high end cables were a crock, well I still think that " HIGH " end cables are BS. But there IS a difference, at least to my ears, between a $30 pair of interconnects and a $200 pair of interconnects.
I am also very interested in the EA Synchro Mesh reclocker. I am curious to see / hear the opinion of anyone owning a Sonos ZP80 / 90 and using a EA Synchro Mesh.
