Features & Highlights:
-
Don’t let the low price of our products fool you. It costs us just as much or more to make our amplifiers as our competitors amps that cost 1000’s of dollars. We use only top-quality components inside and out like audiophile approved binding posts and gold-plated RCA and XLR input connectors. The 4-layer PCB boards are also gold plated. We are a small company and one of the very few that actually design and manufacture all of our products ourselves. Others just purchase amp modules and power supplies from a few well known companies and put them in their own cases. We have over 15 years of experience designing and manufacturing audio amplifiers and our product have always been known as “Giant killers”. We keep our overhead low and design and manufacture ourselves. We sell direct to you so no middleman pricing and markups. No snake oil or smoke and mirrors sold here, only the highest quality products at extremely reasonable prices. Made In The USA!
-
Heavy gauge steel chassis with black textured powder-coat finish. The thick CNC machined and anodized aluminum front panel is available in three colors. Composite back panel with either gold or silver plated graphics (gold with red anodized amps and silver graphics for silver or grey anodized amps). Extremely high-quality build and engineering.
-
The all-new power supply is Full GaN powered PFC LLC converter. This Power factor corrected power supply with standard IEC power cord voltage input of 85-265 VAC can be used world-wide with no adjustments or switches to change. New technology allows us to make a very small compact design that is capable of very high and stable power output with incredibly low noise.
-
The new GaN amplifier modules in these amps are also a new design. Besides the incredible performance, the full balanced Premium Mono amps feature a post filter feedback design with an XLR/RCA selection jumper. A 3.5mm 12V trigger input is located on the back panel. Technology has come a long way the last few years and you no longer have to spend thousands of dollars for a 200 pound amp for the highest level audio performance. Our Premium Mono GaN amps easily hold their own with the best amplifiers available today, and at any price.
-
Full protection circuit suite with front panel error indicators and a three-second mute delay when turned on. Features over and under voltage protection, over current protection, and over temperature protection.
-
Easily power speakers with loads down to 2 ohms.

I bought a pair of the “competitions” well-reviewed GaN mono blocks that were on sale. You were right, your design blows them away! These reviewers have no clue what they are talking about. I’ve known this for years, but just wanted to see what the hype was about, and knew I could sell them easily.. There really is no comparison, yours are 10x better sounding with my associated gear upstream.

I want to thank you for encouraging me to continue to listen to these Premium Monoblocks. I’m not sure what tuned up; my ears, the amps or both, but they’re staying with me. The depth and detail they uncover make listening to older, familiar music a whole new experience. Newer tunes with updated production technology just jump out of the speakers.

I’ve listened intently for several hours. Admittedly the amps may not yet be broken in. Nonetheless, and even if they didn’t develop any further, they sound, well, not “good” or “rich” or “tonally dense” or …. They just sound “right.” The tone, timbre, dynamics, low level detail are about as good as I’ve heard over 45 years. In fact, my tube amps remain dormant. Let’s say that I’ve never owned exotic equipment, i.e., very high priced. But I have owned equipment, both glass and sand, that every audiophile would consider high quality (Sim Audio Moon Series, Pass, Manley, VTL, Cary, Nagra, Bel Canto, Conrad Johnson, Mark Levinson, etc.) I prefer these amps to any amp I’ve previously owned. The low level detail, tonal purity and timbral complexity are addictive and presents as just “right.” I don’t find myself using words I traditionally used to describe amps of previous vintage. I just can’t believe that these inexpensive, small, light contenders are knockout artists.

I had a buddy come over tonight with his Class D amps (I won’t mention the name but their amps are highly regarded). Your GaN monoblocks left them in the dust.

Keith Herron came by tonight to audition your mono blocks with another couple friends. He was impressed. He said the sound was very transparent and not as “thick” as my old amp—the Schiit Vidar. He really liked it. We listened to all sorts of digital and vinyl sources—classical, pipe organ, jazz, female vocals, they all sounded great. Congrats! It’s ironic. Keith is definitely old school but you’ve presented him with the future and he respected that.

WOOOOOOOOOOOOOOOW !
I can’t find any other words! I have a collection of amplifiers Levinson, Pass , Emotiva, Rotell , Red Dragon and a few custom built! I’ve have Adcoms, Llano’s, Sony es. Tom I’m not trying to impress you but I can’t say I have owned “anything” like this! All I can say the best part about any and all of my collection is here! My analogy when I told my friend is, this is the difference between cleaning your glasses and thinking that they’re clean and the optometrist cleaning your glasses and you know you have not been cleaning your glasses. I can’t say this is something I’ve never heard before! But I can clearly say I’ve never heard all the best attributes of any amplifier I’ve ever owned or heard all in one box! I can’t wait to see what going forward will bring! I will be back for a second pair! I have 3 setups, I want more! Next pair in white please! Standing ovation, sir

You know what they say about bi-amping or tri-amping your speakers? Put your best sounding amps on your top end – and I did just that with these Custom Shop GaN FET Balanced HP Mono-Blocks when I connected them to the highly reveling tweeter ribbons of my now tri-amped Apogee Full Ranges. I was already running a pair of well regarded and great sounding 65 lb class D ICE based stereo amplifiers design specifically to run 1-ohm Apogees and I was quite satisfied with them in a bi-amp configuration on these three-way ribbon speakers, but I always thought that the extreme high-end was a bit grainy. Originally the Apogee Full Range bass panels are electronically crossed over to the mid-range ribbons which are crossed over passively to the tweeter ribbons. Electronic crossover is done through DSP using a DEQX Pre-8.
Before I started to eliminate the original passive crossover, I begin to search of a couple of suitable mono-block amps to drive the tweeter ribbons. The criteria was that I had to be class D, since here in Florida I don’t need any big heat generating power amps turning my listening room into as sweat shop – been there done that. I then ran across an ad somewhere for Class D Audio USA. The price was right, newish GaN FET technology, and a 15 day return policy if I didn’t like it. I said what he heck, lets give ’em a try! To be honest, at that price for brand new power amps, I was fully expecting to be sending them back with a week, but oh my, I was totally blown away with the detail and smoothness on the top end. The graininess was totally gone. Just beautiful. They are keepers! I wish that I could comment on what they sound like under 4.5kHz. Maybe one day I try some more of these amp on the mid-range and bass, but for now I’m good.
Oh and don’t worry Tom, I didn’t connect the 0.88-ohm Apogee foil tweeter ribbons directly to the Custom Shop GaN FET Balanced HP Mono-Blocks. I padded the the tweeter ribbons out with the appropriate six 10-watt Mundorf MOX resistors in parallel so the mono-blocks would be loaded with about 3.6 ohms almost purely resistive.
