Just to follow up, the 1.7's do sound incredible once you have the right components, cables, power conditioning and room treatment. Didn't mean to offend anyone. I can say my current solid state setup does not have any issue with brightness. It's smooth, dynamic and very revealing with a massive soundstage. So I don't think there is an issue with the design of the 1.7's, but one does have to budget extra to get things right (indeed my fault for not realizing that early on) and expect a lot of trial and error. The magazines reviewing these speakers have reference equipment and rooms. Lot's of us buying 1.7's do not, however the low cost tweaks in my prior post can help reduce brightness greatly. Having listened to MG20's for years I do agree with those pointing out differences with the older models, the sound is different. The 1.7's sound closer to planer's from Analysis Audio. Very life like and have more "attack." Because the 1.7's have the ability to reproduce instruments in such a truthful manner any flaws within the system (down to fuses and each power cord) will be highlighted. Perhaps, it may be easier to have a tube component or two in the system, but I have not had the opportunity to try that. Maybe a Rogue Audio Tempest with a Raysonic CD-128 would be a nice combo.
For those that can't get the 1.7's to work or those that are building a 5K-ish system with a strict budget, try an old pair of Martin Logan Accent i's if you can find them. It would not be up to the level of the 1.7's, but the old electrostat's sound excellent, IMO are easier to place in a room and start listening, and the woofers offer much more bass.
