"Every once in a while, a product comes along that is both inspired and inspiring. The Channel Islands Audio PEQ-1 MKII is an exceptional performer, one that calls no attention to itself with any particularly egregious sins of commission, delivering an exceptionally refined and engaging level of performance at a surprisingly competitive price. Even the most demanding LP listener shopping the sub-$1000 phonostage market will benefit from the fact that the bulk of the budget for this device has been allocated where it counts most—in performance and dependability." - TAS

"The highest compliment I can pay the CiAudio PEQ 1 MKII is that it sounds as if its creator actually listened as he designed instead of just measuring. This is a fun to listen to, non-mechanical sounding phono preamplifier that delivers genuine musical pleasure and performs well beyond its pay grade." - Analog Planet

"The level of musical finesse and enjoyment that the PEQ does offer is unmatched by anything I’ve yet experienced at anything near this price. Even if you were planning on spending close to $3k on a phonostage, give the PEQ a spin. If your love affair begins here, that’s a lot of extra money for a better cartridge or some more records. Channel Islands factory direct model (with 30-day return guarantee) assures maximum value. All CI products carry a 5-year warranty, and I can speak from personal experience, CI gear doesn’t break." - Tone Publications

Channel Islands PEQ-1 MKII Phonostage

The PEQ-1 is a versatile design offering outstanding performance with a wide variety of phono cartridge types. This new dual-mono design is aimed at music lovers seeking the utmost life-like performance from their vinyl collection. Dynamic and detailed, yet smooth and rich, with soundstage and imaging to create realism rarely heard. Also enjoy peace of mind with our comprehensive 5 year warranty. Full service information is included in the product manual.

Standard & Upgraded AC-15 Power Supplies Available

The internal design of PEQ-1 starts with a dual AC input (one for each channel). When the outboard power supply is connected, the AC is fed to two independent filter/regulation circuits (1 per channel). These circuits feed the L & R audio stages with ultra-low noise on par with the best battery technologies, and without the inconvenience. There is also a Chassis Ground switch to optimize chassis shielding. The standard AC supply is an AC wall adapter type with a single winding feeding the L&R circuits. This supply is 120V input only. Countries with 220~240V mains must use the AC-15 MKII Upgrade Supply.

Audiophile Circuitry

Input signals are connected via highest quality Cardas™ panel-mounted RCA jacks. The input jacks are routed to two independent mono circuits of identical layout. This assures exact performance from both channels and reduces crosstalk. Circuit topology consists of an input gain stage with selectable resistive load, capacitance, gain, and subsonic filter. This gain stage is followed by a passive high frequency cut, then an active bass boost to create the RIAA equalization curve, then to the output jacks. Careful layout yields a very short signal path from input to output, and a combination of star grounding power supply components/ground plane for the audio circuits, result in a silent background and immunity to EMI/RFI pickup. The entire circuit board is then housed in a heavy steel faraday cage to further reject outside interference, then inside the attractive aluminum outer chassis.

    A superb phono stage for any Audiophile!

    by -

    I recently purchased this phono amp as a upgrade for my system. I immediately noticed a difference from my previous phono stage. Vocal performances seemed to be a lot more realistic while maintaining the warm sound I enjoy. I also noticed that my noise level was considerably reduced. The build quality of the PEQ-1 blows away most all other phono amps in it's class easily. Customer service with the manufacturing company and Needle Doctor was awesome, they answered all my questions before purchasing. A sure fire great buy!

    Channel Islands Service, a welcome suprise.

    Recently, I purchase the Channel Islands PEQ-1 MK II, at the recommendation of Brian, at Needle Doctor.. I live in the desert and my listening chair is a static charge generator. Last week, I got out of my chair and touched my CI PEQ. The static shock was unbelievable. It blew out the PEQ and my phono cart. A dreadful loss. The next day, I contacted the folks at Needle Doctor and they put me in touch with "Dusty" at CI Audio. Much to my surprise, he answered the phone. Dusty is very down to earth and a joy to talk to. He asked me to send the unit, back to him. The day he received it, he repaired it. He also shipped it out, that same day. The CI PEQ is the heart of my analog system. It sounds wonderful. I highly recommend it, not just for the sound, but also for the company that backs it up. I can't wait to get it back. As for the cart, well, I guess its time to upgrade to the Hana SL. hats off to Dusty and the folks at Needle Doctor.
