SX SERIES MONO AMPLIFIERS
starting from $799 each


With the huge success of the original ICE CUBE 200SX, we couldn't hold
back from offering a more defined version of the original mono amplifiers.  
The most important advantage of mono amplifiers is the solid chassis, zero
crosstalk between channels, independent shielding, independent power
supplies, and remarkably less distortion and noise.

The SX series amplifiers offer a huge range of flexibility.  With balanced
outputs ranging from 250 watts to 1000 watts, we can guarantee that these
amplifiers can not be beat!  Each amplifier has independent inputs for a
balanced or unbalanced connection which are easily selected by the
selector switch which allows zero input from the unwanted input.  Our
proprietary input stage was designed for optimal performance.  The dual,
balanced FET input stage offers excellent transparency, and seamless
integration with any source.  Connection of these amps to a tube type
source is a match made in heaven!  

The standard ICEpower engine you will find in our amplifiers, and other
competitors offer state-of-the-art technology and are very hard to beat.  
The ICEpower technology alone, as other companies use for their entire
amplifier, is 80% of what we have accomplished.  Our input stage in
conjunction with the internal modifications add the additional 20% needed
to make ours one breathtaking audiophile amplifier!  Stating that the SX
series amplifiers have little to no heat, incredible imaging, unbelievably
low noise, dynamic bass, super wide sound stage and exceptionally low
distortion doesn't even come close to giving them justice.

Despite what the price might lead you to believe, the SX series amplifiers
offer hi-fidelity sound at a fraction of the competitors price (at the least,
half).  We challenge our customers to find competing units at a better
price.  If one is found, what ever the price, we will meet it or beat it given
that it is indeed a comparable product.  To find an amplifier with this much
potential and at an affordable price, hesitation shouldn't even come to
mind.

*For those of you with smaller, less demanding systems, the SX-250 would
be an exceptional choice with the best overall dynamics.  

*For those who have medium systems, the SX-500 will offer the best
overall performance.  

*Then we have the big boys, for those that have demanding systems or
simply want the power that everyone dreams about, the SX-1000 is for
you.  With testosterone to spare, the SX-1000 can and will power anything
you can connect to the balanced outputs. These amplifiers have the best
balance in sonics we have heard to this day!  If you're looking for the
fullest sound, look no further!

Below is some feedback we've received from the first to receive the 2nd
edition SX series mono block amplifiers

"Hi, got my SX-500's Monday, hooked them up that night with my Cary SLP-03 balanced preamp (new also)
, let it play for one day, last night I sat down to listen and I was blown away these amps sound incredible,
more detail, more depth, greater dynamic range, I swear I good tell that Ray Charles (new sacd) was sitting
at his piano with his voice projecting from left to right instead of forward, big upgrade from my Krell 400xi
intergrated. I bought these on Walter Liedermans recommendation unheard and also since Dan Wright
mentioned he liked the sound ( I have Dan's new phono stage), paid full retail and have no regrets, cant wait
to listen to vinyl tonight!!!!"

"I received the amps today.  They are absolutely STUNNING!  I was hesitant to go for Class D amplification
because I had no prior experience and because some folks seem to harshly criticize these designs on various
internet forums, but I have no regrets at all!  These amps are replacing a McIntosh MC275 tube amp I owned
for a while, which is generally pretty highly regarded and more than double the cost of the SX-500 monos.  
In my system, the SX-500's are a MUCH better fit.  They bring out much more detail/resolution from my
Harbeth Compact 7ES-3's without sacrificing "musicality" in any way.  The soundstage is truly captivating.  
They are a really, really nice addition and I am completely satisfied with both the amps and with your
customer service.  Consider me a very happy Wyred 4 Sound customer."

"I haven’t been this giddy since I passed the bar exam nearly 20 years ago!  My compliments to the Chefs!

That being said, I had a few minutes to do some critical listening (without the interruptions of my 6 year old
son) and man I’m astounded.  I can’t believe that I was about to drop $6,600.00 on a pair of Bryston 7B
SST’s.  Thank God my wife told me not to be so damn impulsive and do some internet research before I took
that leap—perhaps that’s another story.  She obviously was right.  So, to thank her, since she is from
Venezuela, I put on some Santana, “Supernatural” and “Shaman.”  Simply beautiful!  My Kef 207’s are
positioned about 10 feet apart.  My listening area is about 27 x 20, hardwood floors, with a vaulted ceiling
starting at 9 feet and going up to about 17.  Call me crazy, but the percussions and Carlos’ guitar climbed
the ceiling and completely enveloped me sitting about 15 feet from the speakers.  Soundstage you say?  Hell,
I thought I was at a small venue and Carlos was playing live!

Next, Springsteen.  Now I know that there are going to be a lot of folks who are critical of my listening
choices.  To them, I say to each his own!  But, man, track 6 on Bruce’s “new” album “Magic,” “Girls in their
Summer Clothes,” I felt like Bruce’s vocals were descending upon me from on high—cascading down from
my vaulted ceiling, not to mention the acoustic guitar embracing me on left and right and punching me right
in the nose in the center.  Quite a moving feeling I must admit!  If I only didn’t have to go to work tomorrow.  
To hell with it all; if I only was a gambler, I’d sell my law practice and cash in my retirement and dump every
penny I had into Cullen Circuits and Wyred 4 Sound products!  Ok, well, not so fast, but the interposition of
reality can’t possibly curtail or harness my sense of being completely awestruck.

Without the SX-1000s and your email correspondences I wouldn’t be writing this email and I wouldn’t be so
darn happy about listening to music again.  Hope really does spring eternal, especially when there are honest
folks like you (and Cullen) who dare to eschew conventional wisdom and labor to bring musically untalented
people like me the great, great gift of music at a reasonable price!  Thank you!"
