dagogo.com - Review of the U-545 Sound Lab Speaker
Originally called the U-4iA electrostatic, as it was in the review, this "reflection" was perhaps a bit rambling at times but did describe the essence of the new 5' tall speaker. Like all Sound Labs, it is transparent, deserves the best equipment you can put in from of it, and is really happy with at least 200 real watts per channel, if not more.
Counterintuitively, the smaller panels are less sensitive than their larger range-mates. Many people look at them and think of the QUAD (even though they are bigger) and reckon they can and should drive them with a 30 WPC amp or they will "arc" them or fry their voltage blocks. This is far from the truth. The last two generations of SLs are reliable and tough, and the latest iteration is even more robust!
The reviewer described the U-545s as having a larger "sweet-spot" than flat panel speakers like the King Sound or QUAD, is more dynamic and coherent, and goes down much lower. I like dagogo.com - I just wish Justin could have reviewed the speakers with his equipment! However, I did learn of some new brands of electronics and so on that I have never heard of.
M-545 and U-545 will be a blessing to those who require a smaller form factor. We are expecting our production versions shortly (the first pairs went to Japan) so you'll be able to visually compare the (now) U-745 speakers to the U-545s in the same room.
We'll give you our listening impressions.
Then it's your turn to come in and listen for yourself. Remember these speakers are custom made in the USA for you!
