Integrity Research & Development "IRD" Purist LLC-P 1B Elma 24 Stepped 0-12 dB Gain Solid State Preamplifier Black Face Plate Option

The IRD Purist LLC-P was designed by Curt Wishman, an American living in Thailand. The unit offered here is one of the scarcer final 1B units with an entirely revised printed circuit board. Curt took all the constructive criticism from reviewers and consumers alike and redesigned the Purist LLC-P with further improvements over his original offering.

The chassis is hefty 23 pounds steel with a black anodized brushed aluminum faceplate, 3 knobs and 4 feet which are machined stainless steel. It's built like a brick $#!+ house... So well I could probably ship it without a box, the delivery truck could explode, and the Purist would survive.

It uses a quad arrangement of AD797 op-amps and a Takman resistor stacked Swiss Elma 24 step volume pot along with a huge toroidal transformer and RFI/EMI filtered IEC inlet.

On the face plate there's a power button, input selector switch, 0, 6, & 12 dB gain settings, and volume control. On the back there's 4 RCA inputs and 2 RCA outputs for bi-amping or a active subwoofer.

Made in Thailand and sold direct however if it was made in the USA and offered through dealers/distributors with a Stereophile advertising budget it would have had to retail for around $4K. Sadly this was IRD’s only preamplifier ever offered although they had two higher prototype units in a preproduction state. When their US financial backer passed away nothing else came to fruition.

How good is the IRD... Well it gave my Sierra Audio K2 a $5K solid state preamplifier a run for it’s money. Also the year after IRD fell off the radar screen MBL in Germany copied the Purist 4 AD797 op-amp gain circuit in their model 6010 $23-27K solid state preamp.

The Purist synergy wise works well with any Solid State or Tube amplifier.

I'll post more photos tomorrow.

Fully functioning it's conservatively rated as 8/10 condition with no discriminating marks worth mentioning.

My price is fully shipped in the USA and there's no additional PayPal % up-charge.

Thanks for looking and please feel free to ask any questions you might have?

Generic 15 Amp IEC Power Cord.
