Manley Labs Chinook Special Edition

  • Sale
  • Regular price $2,599.00


So here's the deal... We had some pictures taken (they are not here yet) and the units in the photos are open stock and avaiilable. They have only been plugged in for the light to turn on in the front. Call and ask if they are here. The regular price is $2599

Okay guys and gals…you’ve seen my video on this. If you haven’t, see it below. I will say this again: The Chinook is unlike any other phono stage at even twice the price. I know the tube phono stages that are available for $2500 because I have them available to me to sell. I’m a dealer for them (I won’t say who they are). But I can’t in good conscience bring myself to sell them, knowing I have the Chinook to sell!

The $8400 Manley Steelhead has been considered the gold standard in tube phono stages. But if you don’t need inputs to run three different cartridges at once, a line input, or a remote control, this is the answer.

Nothing up to $5000 will compete with the Chinook for sound quality and quietness. The build quality is impeccable. And it’s super flexible so no matter where you go in cartridges down the road you will be able to fine-tune loading and capacitance perfect for the cartridge you own.

But I have to tell it like it is. The Chinook is the one. Everybody wants a Steelhead. It’s the best period. Not everybody has $8400, and not everybody needs inputs for 3 tonearms and a remote volume. If you’re one of those folks here it is. So I got thinking: It’s very popular to use the Chinook with PrimaLuna preamps and integrated amps.

Wouldn’t it be cool if I could offer the Chinook in black and silver to match instead of the “Pro Audio World” Chinook finish? Don't get me wrong, the Manley color which is a hint of blue and purple is slick, but it doesn't quite match with PrimaLuna or most other hi-fi we sell. So I asked them to make up the faceplates, and while they’re at it, we got rid of the vestigial rack-mount holes. It looked great. But what to call it? How about Chinook Special Edition.

Then, to make it a real Upscale Audio collaboration, we take out the stock EH 6922s, and replace them with Upscale Audio graded and tested, cryo-treated Philips PCC88s. This is done at the factory, so you're still getting a factory-sealed piece here, don't worry. We've had great feedback from Chinook owners on this tube, and we knew it'd be a great little addition to this Upscale Audio exclusive piece!

{C}Like the Steelhead, each channel employs the two triode sections of a 6922 for amplifying duties with highly accurate passive RIAA equalization networks. In the Chinook, the signal is then directly coupled to another 6922 dual triode serving as the output driver in a White Follower configuration. This output stage circuit is our favorite because of its super-low output impedance and beefy current-driving capabilities. It can drive long cable lengths and difficult loads, tube or solid-state. Bring it on. No wimpy cathode followers here!

Setting up the Chinook couldn't be easier. There are two internal settings for optimal gain: 45dB for Moving-Magnet cartridges and 60dB for Moving-Coil cartridges. Set it and forget it! The back panel contains DIP switches for adjusting the input resistive and capacitance loading values. 31 possible options between 26 and 800 Ohms plus 47k Ohms and 7 capacitive loading choices between 50 pF and 350 pF provide flexibility to match any cartridge and fine tune the tone. Audiophile-grade and time-proven componentry is used throughout, embodying Manley's dedication to seductive sonics, combined with the reliability that professionals around the world depend on. At just about a quarter of the price of our revered Steelhead preamplifier, the Chinook's focus is on elegance of design, careful execution, efficient construction, and appreciable quality.

Designed and built in California, the Chinook exemplifies Manley's commitment to our local community and to a simple, clean, and quiet signal path. The Chinook demonstrates the supreme linearity of vacuum tubes while providing the flexibility needed to embrace any turntable setup. Everything from the most exotic 180 gram audiophile pressing to 25 cent thrift-store classics will be reproduced accurately and musically.
