All I can say is this amp "Rocks" or maybe it "Jazzes" or it "Syphonies"... Heck it does it all superbly.
I live in Mexico and I did have some problems running my amp's import. If you get into trouble like I did, you can not hope for better support than the support I received from the people at W4S. A public note of gratitude on their post sales support, they were there shoulder to shoulder. No ifs or buts just hows and whens. However, most people on this forum are not from Mexico and probably could care less about this, so on to the sound experience.
Out of the box I was impressed. Extremely well packaged. It survived air freight and complicated customs handling without a hint of abuse (not even the outter box). It has a very well presented and thorough manual. I am not much of a manual guy (break first read later) and for an amp, a well presented and thorough manual, it is not a primary concern. However, the attention to detail struck me.
I received the amp before my processor, so I tested it on a Rotel RSX-1065, formerly using and ADCOM 7605 Bi-Amping 2xB&W 683 and the Rotel powering 3xB&W 685. The W4S went in to power the 2 683 first single amp (1ch per speaker), then bi amp (2ch per speaker). The source was fed by an Adcom GDV-870, bitstream.
Out of the box, I knew I had a winner and that all the extra effort required to import the unit was worth it. However, I consider myself very picky. Using 1 channel amp per speaker (a reasonable comparison to the Adcom Bi-amp configuration), I did notice some hindrances. I found the amp very rich in the lows, bringing sub frequencies to notice that the Adcom had never been able to reproduce with these speakers. Over all, the sound was much richer and (I hate clichés) musical. All this did have some draw backs. I found a little less clarity in the mid highs and I found the highs a little lacking.
Despite this, the amp was hands down a winner in my first impression test.
Despite common sense or everything I have learned and forgotten as an engineer, these units, or at least the one I received, do go through a burn in period. After about 3 or 4 hours of continuous use at bothersome sound levels, the staging opened up considerably. I began to perceive the detail I was looking for in the mid-highs and the highs and ultra highs became present.
WOW is all I can say.
Eventually there simply was no point of comparison between the two amps. The musicality and richness of the W4S without any lack of clarity or staging was just incredible. It got to the point that the person lending me his system for the test requested I take my amp home since he was not in a position to upgrade his set-up.
With the Anthem Statement D2v2 in front, Arc room correction engaged, I am finally, after 20+yrs, satisfied with my sound system. I have even postponed upgrading my source equipment.
