Perla Audio Signature 50 Integrated Amplifier - DEMO [Expired]

no longer for sale

We just received a new demo Perla Audio Signature 50 Integrated Amplifier with digital volume display.  So our original demo unit is now for sale.  The unit for sale is about 1 year old and has the older volume control without display (the volume knob shows where the volume is at).  Sonically and performance wise this is no issue, but we want to show the new version as that is what customer will receive if they purchase a new unit.
This is an amazing amplifier, and so smooth I would swear I was listening to a tube amplifier if blind-folded!
Here are a few review highlights and specifications:

"The Perla Signature 50 seems to be as perfect an integrated amplifier as one could hope to find. It possesses the liquidity and harmonic richness of a first-rate tube amp, combined with the extended range and total authority of a potent solid state amp. It is utterly non-fatiguing but fully revealing. In short, I love it. And I will add that while its sonic quality is its most important virtue, it is also, in its unostentatious dignity, a handsome amp to behold, obviously solidly constructed and simply but beautifully appointed. Finally, the owner of Perla, Shane Duffy, and his Audio Archon dealer Mike Kay, are both sincerely dedicated to customer satisfaction. I feel fortunate to have joined the Perla family, nor have I received any rewards for writing this testimonial-other than at long last achieving the elusive goal of audio contentment."-Mark, Satisfied Customer

“The system from Perla Audio was impressive, with a smooth tonal balance, natural dynamics, and absolutely spectacular imaging. Instrumental and vocal images had a rare tangibility and vividness, existing in space completely detached from the loudspeakers."-Robert Harley, The Absolute Sound

"The Perla Audio Signature 50 has many superlative qualities to offer the music lover searching for an integrated amplifier.-"Terry London Home Theater Review, Posted May 20, 2015

"Righello monoblocks ($9000 each), and Motif phono stage ($3500) were producing smooth and deep sound..."- Jason Victor Stereophile Magazine, Posted: Jun 3, 2015

"The whole system sounded so perfectly balanced at 6pm on Saturday that I didn’t even ask for specs on the gear. But excellence in sound is only a small part of why I love insane audio. Fortunately, the Perla guys cover the rest of the bases, too. These guys really are on to something. Check them out." -Malachi Kenny 


The Signature 50 integrated amplifier is a true dual mono that delivers an extraordinary sound quality at an affordable price. This integrated amplifier is a class A/B rich amplifier and uses a push/pull output and driver stages. It uses a single ended input voltage gain. Two volts peak to peak for full output. This amplifier is a “0" negative feedback design. It delivers an authoritative 50 watts per channel. This innovative design has NO CAPACITORS in the signal path. It has an astonishing power supply capacitance of 216,000μF (.216F), using 8 electrolytic capacitors & 84 polypropylene capacitors. This unit is fully 'PI' filtered in its AC and DC filters for ultra-low noise. We designed this amplifier with a 2x bridge rectifier doubling the diodes in the bridges to lower the impedance and we use ultra-low noise Schottky diodes. This incredibly efficient design consumes <6 watts of power at standby. Engineered using only state-of-the-art components such as our high-quality selector switch with 24k gold plated contacts, two 160VA toroidal power transformers with magnetic and static shields encased in a 2.6mm steel case. This unique unit is designed with a forty-eight (48) step precision switched resistor volume control, along with a custom made aluminum remote with a carbon fiber inlay. This unit uses a high-quality military grade power switch with an illuminating blue LED indicator. The Signature 50's well-designed faceplate is integrated into a non-resonant chassis milled from solid billet aluminum and given a beautiful stealthy black anodized finish. Every component is hand soldered to our custom made 3.35mm thick 2oz copper 24k gold-plated PCB boards using Cardas ultra-pure quad eutectic solder containing a proprietary blend of silver, copper, tin & lead. The Signature 50 integrated amplifier is designed for an extraordinary and relaxing experience, every audiophile's dream come true.
