Have you guys ever heard of a company called Usher (www.usheraudio.com)?
They supposly makes high end audio equipments and several of their speakers
(the S520, compass series and stuff) have nothing but rave reviews on
magazines like sterotimes (or something). The prices of the products in
Taiwan is a bargain compared to the prices in the US (for example the S520
costs about 350 US but in Taiwan it costs only 4000NT or around 120 dollars
US) so anyone used their stuff have anything to say?
If you like the way they sound, then they are great. If you don't, then
they are junk. Never buy speakers you have not listened to personally.
Speakers are way too personal to ask anyone for input unless it is in
relation to quality (of the device, not the output).
One thing I might add (after spending a lot on high end speakers for
many years) is that once you get them home, you seldom notice those
subtle nuances that you hear in the store when doing A-B comparisons.
It's a good thing to remember if you want to keep costs down.
Very true. But there is one exception of a product that is so far below
par on quality of any type that it has to be mentioned here so that
future audio consumers never ever make the mistake of actually
Wow, a topic on rec model rockets that i'm an expert on. Before and
during my last 11 years as a Tripoli member (I fly at Black Rock and
LUNAR) I have bought and built numerous hi-end speakers. I most
recently "blew up" a pair of B&W P-6 speakers and rebuilt them (mid
cones and crossovers) from JM Labs/focal cones.
Usher ? Yes a newer and well reviewed company with some great products.
I'm sure if you buy a pair you will love them. BUT consider, build a
pair of loudspeakers yourself with Usher cones. Google "Parts Express"
or any of a number of worldwide loudspeaker suppliers and you will get
about 10 times the value for the $$ and effort you put into it. As far
as building your own cabinets, just buy pre-made, stained or veneried.
Then,buy a good solid state amp and pair that with a tube pre-amp some
(like Dared) even come with a remote. Nowq you will have a giant killer
of a system, that even stereo salsmane from your local high end store
won't be able to touch for $5000.00 bucks

I'm curious why you recommend a tube pre-amp and a solid-state (power)
amp; I'd expect the exact opposite to be optimal.
I've always been under the impression that the putative advantage that
tubes have over transistors is that they don't "hard clip" when
over-driven. In other words, if you drive them to the point where the
output voltage approaches the supply voltage, the output waveform
doesn't have a sharp transition to a square wave; instead, the gain
falls off as you approach the supply voltage, resulting in a rounded
transition, and a much less harsh-sounding form of distortion.
For a pre-amp, where you're dealing in voltages of around one volt
peak-to-peak, and low currents due to the high-impedance inputs to the
power amp, it's dead easy to design a solid-state amp with plenty of
"headroom" to make sure that you never come close to over-driving the
amp. Where you run into issues is in the power amp, where you need
higher voltages and higher currents, due to the higher output power
levels and the low-impedance speakers.

Well, I heard that the S520 is a gem, I listened to it and I was like, how
the hell can a little speaker like that sound so big? I heard theres a mod
you can have done that makes it sound even better, but where can I buy the
parts kit for that kind of mod? I am not shipping the thing to America and
have it take the round trip and pay 3 times the cost of the speaker just for
Just to reply to Rick, who must by an engineer. I'm more of an
experimentalist (same with rockets) than an applied theorist. Most tube
amps (Mesa boggie exempted) have a power range under 30 watts. I've had
success with 250watt mono blocks paired with the Dared tube pre-amp. I
can drive these suckers (and they only have a 5 1/2 inch wide cone) to
very loud rock concert levels. This is my preference , to recreate a
live rock concert sound on two speakers. I recently ditched all my
surround sound equipment (Lexicon) and multi speakers for two rebuilt
B&W's and a dedicated subwoofer run with a professional crossover. I
chose a tube preamp becauce I've been down the long, cold, and
expensive digital road before. It's a lot of fun listening to tubes,
their quirks and faults notwithstanding. Besides, some of these new
Chinese companies have produced some beautiful and reasonable priced
equipment. I've also had very good luck with tube life, having run a
set of 3 in the Pre for almost 2 years with just a slight loss in
volume. I can hardly wait to replace the set with new matched
electrohamonix set, about $28.00 bucks. Also tube preamps need no
rebiasing, but tube power amps do. If you think you are audiophile you
owe it to yourself to run/own some tube equipment once in your life !
Hey guys I just got the Usher AU9000 and a pair of S520 and now I can rattle
the ceiling tiles off with the bass! I bet a computer speaker in the same
price range (I paid like 5-600 US dollars for this setup) cant even do
that... I'd test how loud it can get but I think it might attract unwanted
attention. The amp can do 165 watts per channel by the way... and the
thing's weights like a ton (16Kg to be exact)
Well if rattling the walls is your game crank it up with the 1812 Overture
by the Boston Pops with them using the Mass. National Guard 105MM howitzers
for the cannon fire. Now that rattles some dorm rooms! (this of course is
all theoretical and I was not in room 308 Bldg 412 on Ramstein AB GE during
this hypothetical occurance.) he he he he he (evil Vincent Price laugh)
And furthermore I had nothing at all to do with those four guys soiling
themselves at 0400. Nope wasn't me I was at work at the time. Timer what's
