Audio Alchemy OM-150 Plus Digital Line Controller w/Power Station 3, Digital Decoding Engine v1.1, second DLC & PS3

This listing is for an Audio Alchemy Overture OM150 power amplifier with PSU150 power supply, the Direct Line Controller (DLC) pre-amp with Power Station 3, remote all in working order along with an untested Digital Decoding Engine v1.1 w/PS3 & second DLC. Second DLC appears to be new but without it's own power supply or remote.   

These components have been lauded for their warm sound but with superb detail. After I bought the OM150 one of the channels wasn't up to snuff so I had Geoff Cook of Grateful Dead Wall of Sound fame (sound engineer and circuit design consultant) tune it up. He also contributed to Bob Carver and James Bongiorno of Ampzilla. There's a mark on the side of the OM150 and PS150, and the neoprene feet on the used DLC are deteriorating,  otherwise I'd say 9 out of 10. Amp ships in original box and includes a schematic. Shipping info is estimated. More pictures available.

From other others:
Product Description 150Wpc (into 8 ohms), 250Wpc (into 4 ohms) solid state stereo amplifier, class A up to 20W (40W into 4 ohms) with tube like characteristics.
The OM-150 has 3 pairs of low beta droop Toshiba 2SA1302/2SC3281 for the outputs, a single pair of 2SA1302/2SC3281s for drivers, and then 2 pairs (paralleled) of Toshiba 2SA1306/2SC3298s as the VAS. It can deliver some current for sure..... 

The OM 150 uses a dual differential input (BJTs) and a mirrored darlington VAS. The main power supply of the OM-150 is 20000uf per channel and an additional 9400uf for the input stage up to the VAS. The OM-150 has a separate outboard power supply box with the transformer. 

"The DLC (Digital Line Controller) was one heck of a preamp. It was very affordable, simplistically laid out, remote controllable and actually sounded really good. So good it made it into Stereophile’s Class C recommended components. It has 4 line inputs and 2 preouts which is very useful if you want to hook up two amps in a bi-amp configuration. Although it has an outboard power supply, it operates more like a passive preamp with an active volume control. Sound wise, it is pretty transparent sounding with a nice mid-range and detailed highs. It may not have the darkest background as compared to passive preamps from NVA or Channel Island Audio but it is “colored” in the “right way” which makes it a very entertaining preamp to use."
"I  bought this unit (DLC) brand new from Audio Advisor back in 1996. Other components have come and gone. I have upgraded speakers Stereophile "A" level, upgraded cables, amplification, etc., even added the Integra DTC 9.8, as the HT processor in my system. The DLC has continued to serve as my 2 channel pre-amp for high end listening, with addition of upgraded power supply. I appreciate it today even more than when I bought it. The fact that it has two identical pre-amp outputs makes it convenient to work into speaker set and HT system where I can integrate sub and other sources seamlessly. Fact I can have one input volume at a cost db for pass through to Integra for front mains is wonderful. I've brought home other pre-amps over the years to compare, and I still haven't found anything in the $1-2k range I like better for sound and convenience. I think this may be one of the best purchases I've ever made for value/performance/longevity. Hats off many years later to Audio Alchemy (Dusty and crew) for really creating a perfectly useful and high performing piece of gear."
"I've finally got around to commenting on this fine pre-amp. The A/A DLC came available on Ebay one day. I had heard quite a bit about it but decided to do a little research myself. I ended my research on the Stereophile site. From all accounts the unit was highly recommended so I bid and won the item. Here we are some 3-4 yrs. later and I'm still amazed at the units ability to just get out of the way of the sound. I incorporate Magnaplanar MG-llc's for speakers and have them presently bi-amped. The DLC offers 2 main outs which dramatically simplifies the bi-amp procedure. I can remember setting the unit up and allowing it to warm-up for about 45 minutes. My wife, who is one of the most realistic "audiophiles" I know, was the first to comment, "the soundstage depth is amazing". I agreed and also noticed what I thought was less bass, however, when the unit was presented with known "bassy" music, the quality of the bass was outstanding in it's ability to be multi-note, clearly delineated, incredibly fast and very powerful. After a couple of evening of listening I realized the, what I thought, lack of bass was in fact a lack of boominess or sluggishness brought about by slow and sloppy bass reproduction. I compared this unit to my Reference Line Preeminence One passive and found the A/A DLC to be holding it's own rather nicely. The DLC simply blew away my (modified) Sonic Frontiers SFL-1 hands down, even with the SFL-1 on the "direct" output. The A/A has the unique ability to disapear into a large, deep soundstage that reveals the venues the music was recorded in most accurately. The tonal quality was most impressive and the musicality was so enjoyable, it allowed for listening sessions late into the night with seemingly no listening fatigue what so ever. I most certainly could go on but I belive what is most important here is the price/performance ratio. I can't even begin to imagine what is out there that can compete. Knowing full well the unit is entirely controlled by it's remote only, it is imperitive that you either attain a learning remote or absoulutel positively not drop or damage the original. Very highly recommended !!!"
"I have a lot of preamps, and have enough hifi gear to have a different system in every room of the house. I am very picky about preamps, because they amplify the low-level so many times over they can make or break your sound if they have any coloration at all. Much more critical than power amps, IMHO. I use the DLC in my bedroom system, which is to me my most critical listening environment. I typically don't play really loud in there, but I want to hear everything... every nuance of every instrument with great detail and depth with precise imaging. The DLC definitely does that. I sometimes run with no preamp, just CD straight to amp. The DLC is as close to that as I've ever heard (or, more accurately, not heard). Just switching and really clean, quiet gain. I currently use the DLC with a Marchand amp (another true bargain) and old Polk Monitor 10's, but the configuration changes reasonably often. Completely opposite end of the spectrum from my old tube preamps, which I like, but they definitely change the sound. I'm glad I read Audiophile's review of this. A truly amazing bargain."
