I am glad to be selling Wyred 4 Sound power amplifiers to the AudiogoN community. Wyred 4 Sound amps are manufactured by Cullen Circuits of California. Still doesn’t ring a bell?

Cullen Circuits has been in business for many years and has manufactured amplifiers and other electronics for the following: PS Audio, Ampzilla, Infinity, Genesis, BGW, Camelot, CAT and many more. Now are you staring to get the picture?

Wyred 4 Sound amplifiers are only sold Internet direct, and I am the only distributor. What this means to you is that there are no dealer mark-ups, and therefore, these amps are being sold at about 1/2 to 1/3rd the price of competitive products with, in many cases, substantially higher parts quality.

In fact, the SX-500 MKII shown above is directly competitive with the $4,700 Rowland amps, the $4000.00 Bel Canto, Red Dragon & EAR as well as many other highly regarded amplifiers utilizing the EXACT same B&O ICE modules.

Before you buy a Rowland or any other ICE based amp, you owe it to yourself to give me a call to discuss whether one of the Wyred 4 Sound models would be suitable for your system requirements. If sonics are what matter and cosmetics are secondary than this is the product for you. We do look good, but we sound GREAT!

Here is what Dan Wright, the owner of Modwright had to say about his personal Wyred 4 Sound amp:
"I am currently using a Wyred 4 Sound amp that I purchased from Underwood Hifi - www.underwoodhifi.com; 770.667.5633. Walter Liederman is great to deal with and is the ONLY dealer for Wyred 4 Sound products.

I bought a 4-CH amp for use with my CS2's. It has two 250W modules and two 150W(?) modules. I have not had a chance to hook up the CS2's with it yet as I am still scrambling to find my extra XLR cables, but I AM running the 250W modules to drive my Greybeard KB/3/3's 4ohm nominal (90dB) and 20-20Khz flat response. These things are FANTASTIC. Also, at $2495 for a 4CH amp with THAT much power, you really can't go wrong.

As far as listening goes, so far, with my big Greybeards being driven by only 2CH of the amp, via the 250W modules, I am VERY impressed. Bass is thunderous and controlled. Highs sparkle with no fatigue and the noise floor is NON-EXISTANT. We are driving the amp with our own tube equipment. HIGHLY RECOMMENDED!!!"

All Wyred 4 Sound mono amps have a unique buffer input circuit. In addition to sounding better than the basic input stage of the ICE amp it has an input impedance of 61K that makes it work properly with tube preamps as well as solid state. But, if you are using a tube preamp, the 10K or even 20K in balanced mode of the stock ICE amp is too low. This is indicative of the kind of care that has gone into the development of all Wyred 4 Sound amplifiers. We even had the new input stage specially designed for us by Bascom King. Bascom has done design work for many of the best hi-end brands in the business.

The SX-500 MKII has both balanced and single ended inputs. It features both short circuit and over current protection.

With distortion below 0.02% & a damping factor of 2000 sonics are exceptional. They have superb low level resolution, exceptional transparency and tremendous bass detail and extension. They sound as good or better than the other 250 watt ICE based amps that have received Class A reviews all over the world. These amps come with a 3-year factory warranty.

These are mono amplifiers and the price is $899.00 for each amp. They can be sold in any quantity from 1 to 7 for a full 7-channel home theater system.

Features are at the bottom of the ad.

We accept Visa & MasterCard as well as money orders. Read our over 10,500 points of AudiogoN #1 rated feedback and then call us at 770-667-5633 to discuss these fine amps and other Wyred 4 Sound models.

International orders are handled by bank funds wire transfer only.

They also make these mono's in a stereo version at only $1495.00 + frt.

I also have the other amps in this line. The 1140 watt mono amp is only $1199.00. It does 570 watts into 8 ohms & 1140 watts into 4 ohms.
