I am a dealer and don't pay Audiogon fees for selling products. Email me at underwoodwally@aol.com or call me at 770-667-5633 for fastest response. The Wyred 4 sound SX-1000 MK II mono amps (introduced in late 2008) offer the best value in a high power mono amplifiers available today. They are now available in both black and silver finish.

Please note that these are mono amps and are priced each at only $1195.00 or $2390.00 for the pair.

We also ship these worldwide in 220/240 volts into countries without a distributor.

Compare them to the competition selling for between $4000.00 and $6700.00.

The SX-1000 MKII's received the "Editors Choice" award in "The Absolute Sound" in both 2009 and 2010.

In the August 2008 Ultimate AV review David Vaughn sums up his review of the 250 watts per channel 5-channel MC version with:
In my time with this amp, I have been in audio heaven. When I review a product, I usually look forward to placing my own equipment back in my rack, but that wasn't the case here. After I reinstalled my Anthem, I instantly missed the Wyred 4 Sound, and I immediately put it on my short list of upgrades—it's that good."

Does this amp look familiar? Probably not from the outside, but read on.

Wyred 4 Sound amps are manufactured by Cullen Circuits of California. Doesn’t ring a bell?

Cullen Circuits has been in business for over 20 years & has manufactured amplifiers & other electronics for the following: PS Audio, Ampzilla, Infinity, Genesis, BGW, Camelot, CAT & many more. Now do you 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 is no dealer mark-ups, and therefore, these amps are being sold at about 1/2-1/3rd the price of competitive products and the Wyred amps have, in many cases, substantially higher parts quality.

In fact, the 570 watts per channel (1140 watts into 4 ohms), SX-1000 MKII shown is directly competitive with the $6,700 Jeff Rowland amps, the new $6000.00 a pair Bel Canto Reference 1000 MKII, the $6,000 per pair Red Dragon, EAR as well as many other highly regarded amplifiers utilizing the exact same B&O ICE amplifier modules.

Before you buy a Bel Canto, Rowland, EAR 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 great sonics & value are what matter and cosmetics are secondary than this is the product for you. We do look good, but sound GREAT!

Here is what Dan Wright, the owner of Modwright had to say about his personal MC 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!!!"

Thanks, Dan W.

All Wyred 4 Sound mono amps have a unique buffer input
stage. In addition to better sonics than the stock input stage of the ICE amps, this upgraded input stage allows a perfect match for both solid state as well as tube preamps. The 10K or even 20K in balanced mode of the stock ICE amp is too low for most tube preamps that have output impedance's in the 600 ohm range. Our amps now provide a 61K input impedance, making it a perfect match for tube preamps as well as all solid state preamps. 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-1000 Series II features both balanced and single ended inputs, along with short circuit and over-current protection.

You will find all specifications listed below, but it is worth noting that these amps have a distortion level below 0.02% & a damping factor of 2000 for superb bass control.

Sonics are exceptional with superb low level resolution, exceptional transparency and tremendous bass detail and extension. There are a number of big name 500 watt ICE based amps that have received Class A reviews all over the world. Rest assured that the SX-1000 MKII is as good or better than any of them.

See the technical info at the bottom of this ad.

All Wyred 4 Sound amps are Made in the USA (California) and come with a 3-year factory warranty.

These are mono amps, and the price listed is for one amp. They can be ordered in any quantity from 1 to 7 (for a full 7 channel home theater system).

Features are below this ad.

I also have the other amps in this line. The 250 watt/ch stereo amp is only $1495.00. It does 250 watts into 8 ohms and 550 watts into 4 ohms. It is extremely similar to the 4700.00 Jeff Rowland's less the "Audio Jewelry" look. The 100 watt stereo amp is only $995.00 and is truly dual mono with 2 separate power amps inside.
