Harman/Kardon Signature 2.0 (or, "So You Decided to Buy an Ancient Pre/Pro")

I've been looking hard at buying a DAC/preamp for my main system. I wanted something with a remote, and controls simple enough not to flummox my SO. I was also trying not to spend more than $500. I'd looked at buying a new Emotiva Stealth DC-1, buying a used Peachtree NovaPre, cannabalizing my TEAC AI-301DA integrated amp, or building something up out of Chinese boards.

I'd also seen some older home theater pre/pros that might fit the bill, and was looking hard at trying to find a McIntosh MSD-4. Instead, I found a Harman/Kardon Signature 2.0 for sale locally for $150.

The H/K Signature 2.0 was designed and built in the USA at Madrigal Labs, alongside Citation, Mark Levinson, Madrigal, and Proceed. It had an MSRP of $2500 and street price was $1500-1900.

Most owners didn't seem to buy it at street price, though, instead getting the 2.0 closed out between $250-900. It was buggy as hell, necessitating several firmware updates accomplished by physically replacing the EEPROM chip. There was also a mid-run redesign of the processor board that added DTS (and otherwise improved performance via a new Cirrus Logic chip). By all accounts, Madrigal was able to eventually work the kinks out of the 2.0, but a reputation had already been formed.

Mine is an early example, but has been updated with the new DTS board and final factory firmware ver 2.10a. I've been in contact with Bob Popham at RJPC, who helped design this model and serves as Harman's service center for the Signature line. He told me that, although he used to offer an unofficial ver 2.12 firmware that improved bass management, appropriate EEPROM chips became unavailable around 2008, and he no longer has the software or hardware to write them.

Customer reviews (like these) tend to be fairly positive, but there are complaints about the bugs, and descriptions of sound quality run the gamut from "warm" and "detailed" to "dry" and "2D". By using the H/K Signature 2.0 ver 2.10 as purely as a two-channel DAC/preamp, and changing the processing settings for each digital source to decode only PCM, I should be able to wring every drop of performance out of this bizarrely complex beast.

I'll need to buy a USB-to-S/PDIF converter, and am leaning towards the discontinued Topping TP-C1. I'll also need a learning remote to use on a day-to-day basis. The original H/K remote is WAY over-complicated, but also completely essential for setting up the pre/pro's functions. Buying a cheapie learning remote will save stress for me and my SO, and keeping the H/K remote safely in a drawer will prevent wear and tear.

I haven't actually played with the 2.0 yet, user advice being to set aside an afternoon to set it up. Wish me luck!

So have you set it up yet? I've had this unit since 99'. Its paired with an Oppo Bdp103, Dual1219 with an Emotivia XPS-1 phono stage, Boston Acustics all around, a parasound CSE 6.1 rear center expander VR30 front, VR12 center front and center rear and VRMX for surrounds. Two infinity 10" 100 watt do the low end work. I'm using HK 2200 for the fronts and HK PA 5800 for the rest.
The sound this produces still impresses me to this day. I have never needed anything else. The Oppo and CSE 6.1 is a great add for this unit. There are still some bugs, but they are virtually invisable.
 
Been using the Signature 2.0 for the last week. It did take the better part of an afternoon to wire up and set up. I really liked being able to fully customize the names of the sources on the display. As planned, I turned off all surround sound processing, and there's been hardly a hiccup.

My biggest complaint is that the S/PDIF optical inputs seem to have a loose solder joint or something. One of them only works if it's being held in place just so. The other one seems solid as long as there's a little tension on the cable. I may have to do a little exploratory surgery, but I'm nervous.

The amp I'm using is a Yamaha P2250, a 1980's pro amp rated at 170wpc. It's also new to me. There's no 12V trigger turn-on on, so I added one on via a $15 Iot relay from Amazon.

The remote sucks, so I'll be programming an Inteset universal.

Sound is pretty well dead neutral. No discernible coloration for good or for ill. Some folks might call the midrange a little dry, and coming off an unrestored vintage integrated amp, the bass seemed anemic until I realized it was just a lot less sloppy. Haven't yet played with the tone controls.

Need a better phono pre than the ART DJ PRE II I'm running, but I'm a Mouser order away from finishing a CNC. Can't wait to stick some different amps on the Signature 2.0. Got a Motorola console pull and TPA3116 blue board in the wings that should be interesting comparisons.

By the end of the year, I might take the Pepsi challenge vs. an Emotiva BasX PT-100, as it would seem to have similar functionality in my system at an affordable $300.
 
Nice to still see positive reviews of the 2.0, hope you enjoy it. Had mine for 10 years; replaced it with an Integra 9.8. Mine is a "Z" HK refurb unit, I think I paid $350 new. Bulletproof unit, never any problems, sounded fine when I packed it away. Just liked it too much to dump it; my first digital prepro. Paired it with an original Adcom 555 with B&W Matrix 802s.

I thought it unusual the treble couldn't be raised, only lowered. Still, just a nice looking, good sounding unit. HK still has both owners manuals available. Tried a few different universal remotes, but found nothing better than the not-great original remote. If it had balanced outputs, I would have continued to use it...

BTW, found out about the RJPC too late to get his upgrade.
 
Sorry I'm so late to this party, but what are my odds of finding a working remote for the Sig. 2.0? All I need it to do is manage a couple of analog inputs and send them to an amp. Without the remote I'm stuck, as reading the manual, (after the fact) clearly suggests. Failing that, it would help immensely if someone has knowledge of a decent unit/remote, that can work with the Signature 2.0. 'Really appreciate it.

dpailku, I had the exact same problem.
The Signature is a paper weight without the remote. A shot in the dark, I grabbed a used logitech harmony remote on marketplace.
It works wonders, it allowed me to factory reset the unit, and configure the inputs.
