AMC SOLID STATE AMPLIFICATION SERIES

AMC
SOLID STATE SERIES
Although AMC Solid State Line consists of a large number of components, we had initially selected only 1 component of particular interest for use in audiophile systems ... The 2100 MKII bridge- able Power Amp. After further investigation we added 2 more ... and are even considering a fourth component pending minor modifications we have requested.
Note that we first started out offering AMC's killer-value tube line. What we "heard" prompted us to look into their solid state components. AMC had suggested we would be equally impressed with their approach to SS design which we were told involved the Sanken Mosfet high current delivery power topology, adjustable input sensitivity, buffered outputs, and pro-audio based performance for their preamps. Although we were quite aware of the perhaps old fashioned "Zero-Bling" aesthetics, one look at the prices they were asking for these components was all it took to convince us to "listen". After all, what we were hoping to find was components with killer-performance at very accessible prices. The rest of the story is history ... see below :
AMC 2100 MKII bridge-able Stereo/Mono Power Amplifier - $ 1065
What is striking about the bridge-able 2100 MKII power amp is its massive current capability of 50 Amps in Mono mode ! In stereo mode it kicks out 100W RMS into 8 ohms and 200W RMS into 4 ohms. Mono Power is 250W RMS into 8 ohms... and what is surprising is that you also get adjustable input sensitivity and buffered outputs. Hello loudspeakers with difficult loads ! Bi-amping is the other application of interest. We even combined this Sanken Mosfet power amp with AMC's "delicious" unity gain tube-buffer-output CVT1030se MKII preamp (link to our AMC tube line page) to create a sub-$3K "hybrid separates combo"with MM/MC, HPA output and Bluetooth streaming ... turns out this combo is a "no brainer" !
AMC XAi 2/4 Channel Power Amplifier - $ 950
The AMC XAi 2/4 power amplifier shares the same technical PRO heritage with the XPi
and fits right in to Audiophile Land... they were conceived to be a "desktop pair" squarely aimed at high quality 87db-type Desktop/Bookshelf speakers and headphone listening.
-
It provides either 4 x 45 watts RMS for by-amping, or 2 x 90 watts RMS.
-
It has Input Level controls for all 4 channels. So, bi-amp channel balancing is possible.
Bottom Line : bi-amping with this small power amplifier is a mighty powerful thing.
AMC XAi 150se Integrated Amplifier - $ 1,895
The AMC XAi 150se Integrated Amplifier, offers more power than the 2100 MKII power amp (note : 2100 MKII when in stereo mode) and more massive current capability as well ! In stereo mode it kicks out 150W RMS into 8 ohms with clean dynamic peaks of 255W into the same 8 ohm load. RMS power into 4 ohms is 250W. Its integrated package includes a fully functional preamp stage, a very competent headphone stage, and a selectable MM/MC stage.
Bottom Line : a really bad-ass power stage that will do Jazz and Classical on the fly, but that just loves to "rock".
AMC 2N100 MKII-2 Stereo Power Amplifier - $ 1,200
The 2N100 MKII-2 power amp is the power amplifier version of the XAi 150se Integrated.
It delivers equally hefty current, and puts out 150W RMS into 8 ohm with clean dynamic peaks of 255W into the same 8 ohm load. RMS power into 4 ohms is 250W ... and here again, you also get adjustable input sensitivity and buffered outputs. Ideal for loudspeakers with difficult loads !
This power amp is actually the 2-channel version in a series of A/V power amplifiers that includes 3-channel, 5-channel and a 7-channel versions base on the same Sanken mosfet topology. We only offer these other versions on a special order basis.

AMC Proprietary Technology Features
HCO Power Topology
HCO - High Current Output Power Supplies
Music consists of impulses. However, regular power supplies, and in particular switching power supplies, are designed statically.
The HCO technology, in contrast, provides dynamically much higher power reserves whilst delivering extremely high current output.
Toroidal power supplies, in combination with the legendary Sanken output transistors, unleash the music with all its dynamism and liveliness ... even with difficult speaker loads !
VRI - The Rotary Volume Input Topology
A step-less potentiometer switches the source ... no switch or relay.
The fine signals are passed on to the next amplifier stages free of contact-related losses.
Only what is not lost at the input stage, can also be restituted at the output stage !
