Zesto Audio Andros 1.2 Phonostage Vs Manley Labs Chinook Phonostage - Part I


I’m so far behind on various writing and review projects that I feel I just have to get something out there so people know that I’m still alive! Of course I blame my visit to Capital Audiofest for falling behind with my work – it was a great show and chock full of things I wanted to write about.

Now that the dust has settled from CAF I’ve had some time to sit down and undertake more serious listening along with some frantic note-taking. So up here is a rather condensed and truncated review of two respected and high-performing phono preamps, the Manley Chinook and the Zesto Audio Andros 1.2

There’s a price difference of around $2K with these units, the Manley Chinook retailing for $2700 and the Zesto Andros for $4700. So perhaps you’re thinking it’s a little unfair to be pitching one against the other here, as clearly the Zesto is in a higher price bracket than the little Chinook. My thought however is that a Chinook owner, of which there are many, may see the Zesto Andros as a logical upgrade path, so my notes here relate to that as a premise rather than tossing one unit out because the other is better.

If you need to see the review system components to create some context for this review, then it’s listed in the sidebar on this page.

The Manley Chinook


I won’t bore you with all of the technical specs as you can simply retrieve those directly from the Manley Labs’ website here. But so you don’t have to hop around between websites, here’s a few bullet points courtesy of the Manley website on what you’ll get with a new Chinook, along with an occasional comment from me:

  • The spawn of the famous STEELHEAD !! Hmmm…. is it, really?
  • 45 or 60dB of GAIN can be set internally. Why oh why couldn’t you put a toggle on the back? 
  • Options to match any Moving Coil or Moving Magnet cartridge. My ZYX with 0.24v output worked really well on the 60db setting.
  • Two triode sections of a 6922 for amplifying duties with another 6922 dual triode serving as the output driver.
  • Resistive and capacitance loading values with 31 possible options between 26 and 800 Ohms plus 47k Ohms. Who doesn’t love flicking around those shitty little dip switches with an unwound paperclip?
  • 7 capacitive loading choices between 50 pF and 350 pF. A little down on options compared to Mr. Zesto.
  • Unbalanced Input and Output connections.
  • Made for music lovers! Ah, well then I’ll buy one.

OK, it’s got pretty much everything you need as a vinyl spinner except a remote. So yes, you may have to remove the lid at some point to switch gain, and you will need to get round to the rear of the unit to access those bloody awful dip switches.

Build Quality / Appearance

You’ll either be a lover or hater of the Manley retro/industrial look, personally I’m a little on the fence. Something like a Stingray integrated or even the Steelhead phono is a little too much 70’s for my tastes, but the Chinook is clean and neat and actually quite attractive with its lit Manley badge on the front.

Build quality is excellent. The case/chassis is solid and heavy and the internals are well laid out with not too densely populated circuit boards.

Dimensions are: W=19″, L=11″, H=3 1/2″ and the thing weighs a measly 15 lbs or thereabouts. I want a 48 ounce T-bone not a 6 ounce filet!

Setup and Component Matching

I set the Chinook atop three AudioPoints and also tried it directly with supplied feet. I felt the AudioPoints helped de-saturate some of the density of image, which you’ll understand more when I talk about the sound.

Cabling choices varied from the hard-wired phono cables on the Dr. Feickert Volare Turntable to cables from Analysis Plus, Harmonic Technology (Pro-Silway), Anti-Cables and several others I laid my hands on when switching this unit in and out. All of the cables worked well with the exception of the Level 2.1 Anti-cables, which in fairness were new and not broken in. Each cable brought a very small change to the sound, scarcely detectable in most instances, so I believe the Chinook to be free from any undue finickyness when it comes to hook-ups to the rest of your rig. With the Music Hall MMF-11 as source, I think the Pro-Silway edged out other cables going from TT to phono, and same on the phono to preamp.

I tried a couple power cords but settled quickly on the ESP Reference as I’ve only ever heard this cable make a positive contribution to the sound of the many different components I’ve used it with.

Setup was quick and easy. I had to remove the lid to set the gain to the lower 45dB initially, and flicking the dip switches on the rear of the unit is not my preferred way of making adjustments, but accepted as just one of those minor quirks that I have to learn to live with.

Switching on the unit there’s a 45 second warm-up cycle followed by a subtle click and you’re ready to roll.


The Sound Of Chinook

I didn’t spend any real time tube-rolling with the Chinook. It came with Tunsgram and Amperex NOS tubes and I had Electro Harmonix replacements on hand which sounded good in some ways, less pleasing in others. So the majority of listening was with the Tunsgram and Amperex NOS tubes. It’s worth mentioning that any 6922, 6DJ8, 7308, ECC88 tube can be used, so this is a tube-roller’s dream. Or nightmare, depending on your levels of OCD.

The sound of Chinook in my setup was big and meaty and gregarious, like an over-filled plate of mama’s best lasagna. Flesh on bones was the thing that really struck me most about the Chinook. It’s like stepping from a Krell Pre/Power combo to a classic Conrad Johnson setup. The music has presence, body, scale and nuance. As soon as my brain processed the increase in fleshiness it began (via my ears) to search for the obvious trade-offs – lack of dynamics, air and detail. But that wasn’t to be. Everything was there, where you’d expect it to be and with a pleasing musicality that few phonostages in my experience can muster.

Playing Duke Ellington’s ‘Blues In Orbit’ on 200 gram, (remastered by Bernie Grundman), the sound has excellent pace and vibrancy with images exploding out from a densely populated soundscape. Tracks like Three J’s Blues and The Swinger’s Jump have a high level of dynamic impact that helps give the performance a tremendously ‘live’ feel. Brass instruments have presence and solo horns pop from an inky blackness. The title track is a slow number that pitches Ellington’s piano in a duel with the horns. The sound of piano on this track is one of the best recorded pianos I’ve heard. The horns sparkle with just enough brashness and space around instruments is reconstructed wonderfully.

Since it’s my job to nitpick I have to say that the frequency extremes are where this phono preamp could be bettered. I found the bass to be quite extended but a little lacking in definition. An upright bass plucked and mixed into the background sounds sweet and fleshy and plummy but a bass synth or an electric bass placed more prominently in the mix doesn’t quite have the tautness and definition afforded by other phonos I’ve heard, particularly solid

Once the novelty of the Chinook had passed I spent an evening going through the usual audiophile check list, more for the benefit of my readers than myself. I’m going to save those results for a full Chinook review at a later date, and concentrate here on the differences between it and the Zesto Andros.

We’re of the firm belief that achieving excellent sound quality from a home audio system shouldn’t require one to take out a second mortgage. It should be attainable at a reasonable level of budget, particularly when one is prepared to weave used and demo components into the system mix. This is our philosophy here at Audio Resurgence, we aim to provide our readers with fair and honest reviews and assessments and not to fill your heads with intoxicating hyperbole that encourages you to spend more than is reasonable for quality sound. To this end we’ll review both current production home audio equipment and also used-gear which may be out of production but available via the used marketplaces. 

Reading the above may raise a concern about the veracity of our reviews, given that we may at some point decide to sell on a component purchased by us for a review.  Well, we do our own extensive research before bringing in a review component, and, quite honestly, I don’t want to waste my time (or yours) listening to poor sounding gear and then having to spend time writing about it. So it’s rare that we review a component that doesn’t have at least some virtues that would please a new owner, and we try to describe those virtues along with any negative aspects we encounter, as fairly and honestly as possible.
