PS Audio PWT - cd transport


Category: Digital

When I first saw a picture of the PS Audio PWT transport I did not think too kindly of it, as it appeared to be formed plastic but with reading the PS Audio website info on it, it made good electronic sense to me.

Reading the disc via a ‘read till right’ program – in other words, it does not automatically implement ‘error code correction’ (ecc) programming when misreading a disc, instead it reads and rereads the disc up to 100 times (not utilizing the drive cache) before resorting to ecc. Once this data is extracted from the disc it is sent to RAM memory where it is stored for a brief period. This middle storage point separates the disc from the transport’s output, thereby allowing for rereading till right data (explained above) and eliminates timing errors (by reclocking the data from this point forward, instead of using the clocked data stream directly read from the disc). This memory buffer does not manipulate or change the disc data at all – it’s still what was on the disc, only now more accurate in content and more accurate in timing. This is the data output.

Anyway, after being explained this info by Paul McGowan and Ryan Conway, I was intrigued enough to buy one. First off, I can say that I pleasantly surprised and happy to report that the transport is not made of plastic, its either aluminum or steel, and it is heavy and well damped. But, the remote is made of plastic and is pretty cheap feeling – oh well. There is no buttons on the unit, all input is either via remote or via a touch screen on the unit. The touch screen is a nice touch (couldn’t resist;) – it allows for operation but also displays disc title and song name with album cover art (if the unit is connected to your internet).

But enough with the side show stuff – what does it sound like? House keeping first - I have about 348 hours on it now, it sets ontop of Symposium Rollerblocks,, I’m using a Grover Huffman Sc AES/EBU digital line to my custom Audio Note DAC, and I’m using an Grover Huffman Sx power cable. The rest of my system consists of Atma-Sphere MP-3 pre and MA-1 amps and Quad 988 esl’s. This consists of the base line and comparisions are made against a Accustic Arts Drive 1 mk1 transport.

Now then;

Most obvious is a total lack of digititis – no etching, no “over emphasized” sharp edges, no glare. Instead, you get a VERY organic sound, but mind you, it’s not bloated, softened, or rounded – the best description is ‘natural’. Significantly more liquid than the Accustic Arts.

A dramatic increase in soundstage and dimensionality. Instruments are spread out with plenty of air and space around them. Open air, breath. Whole stage depth presented. Much more extension in my sound stage width, now uncannily extends beyond the sidewalls.

Articulate and detailed, but again no etch or glare. Fast. Slam. Tight. Rhythmic. We have moved beyond toe-tappin’ and have entered the butt shakin’ realm. Very lively. No fatigue.

All is well extended in both directions, bottom to top. Nothing is bloated or sharp. – sonically very clear and focused. Micro and macro detail is really expressed nicely. But, the noise floor is bit higher than the Accustic Arts – not a totally “black” background. Lastly, on very busy passages, I detect a bit of grain – only on pieces very busy with treble (concurrent multi cymbals, highhat, triangles, +).

Putting it all together - Horns, bongos, vibes are holographic / 3 dimensional. Brass horns are “brassy” but not bright or shrill, instead mellow and sexy. Cymbals are crisp and have realistic brassy lingering overtones. Toms and snare are stout. Strings are beautiful and radiate mellow woodtones. While bass is deep and distinguishingly tonefull. Woodwinds are richfully hollow and resonate, Voices are lively, relaxed, and human. Again, my notes continuously go back to “organic” and “natural”. Very ‘smile on your face’!!!

Overall, I find myself really amazed. The PS Audio is literally 1/3rd the price of my Accustic Arts but is truly much more musical. Personally, I think it’s power supply could be cleaner but this does not distract from the organic sounds elicited – actually reminds me of good analogue. The PS Audio is without a doubt a giant-killer for its price-point and I feel I can recommend it without hesitance.

I am wonderfully happy with how well it has synergized and complimented my custom Audio Note DAC. Lastly, I should note, the PS Audio has read every disc I have placed in it without a single stoppage -- can't say that with Phillip's drive based transports.
128x128grateful
You guys had me going. A new concept that might actually play any disc I throw at it (as it should be) Maybe it is time to complement my analog system with a decent digital set up. Oh, then I did some checking and noticed it is FOUR THOUSAND DOLLARS! Forget it.
Hifiharv,
The PWT is available used on a fairly regular basis.It`s an absolute audio bargain at used pricng and worth every penny.This is simply a top tier transport.
Hifiharv and Charles1dad,
I bought the PWT mint for about $1700 on Audiogon. It really is an absolute audio bargain. It is world class. IMO.
Thanks so much for the reasurance guys! Picking one up locally, for a great price, this week end...
Sabai, was especially good hearing your pairing. I'll be right there with ya with that combo.
