Review: Custom line-out to 1/8 v Sendstation Pocketdock with Stax portable system

Construction:
Sendstation is generic mass produced cheapo and comprises dock with line-out and USB2 charging option, plus 1/8 to 1/8 and 1/8 to 2 RCA. I assume the wire is copper but I haven't chopped it up to check.

Custom Silver Cable made by hoosterw on this forum: six inch long, two sheathed solid silver wires from line-out to gold plated 1/8. Covered in black nylon mesh. The line-out jack gives the cable a slightly amateur feel (not the constructor's fault), although sheathing the connector in heat-shrink might help this. If you search on hooster you'll find a picture.

Stax energiser driven from mains (better than from battery, despite a very low level earth hum)(I think it was an earth hum).

Both cables cost around $30.

Tracks used:
Bruch Violin Concerto, Cho-Liang Lin, Chicago Symphony Orchestra,
Saint Seans, Symphony No. 3
Radiohead, OK Computer, Karma Police
Godskitchen Mix, Jam X and de Leon, Can U Dig It
Bruckner, Locus Iste

To start where I should really end up, the difference between these two cables was not night and day and I had to work hard to sort them out. I have accentuated the differences to make this review useful but I'd advise you to carry your own pinch of salt.

The issue of burn-in also rears its ugly head here: the silver cable has been used on and off for a week, but I would normally want to have a cable in continuous use for at least that before I feel it's burned in. However, I've noticed that mentioning burn-in here is like throwing a stick of dynamite in a hen house, so enough on that.

The most obvious contrast between the two is in the bass (I was expecting huge treble extension. Oh well). On the silver cable bass is better controlled with space beneath the notes and greater depth. By contrast the Sendstation can occasionally lose control of the bass, and generally sounds thinner.

With the silver cable harmonies have a richer more sonorous feel - particularly with classical music - and become easier to hear. With a piece like the Saint Seans in the Fourth movement, where the range stretches from the deep bass of the organ to the higher frequencies of the fiddles with a bit of everything including the kitchen sink thrown into the middle, this becomes important. It's easier to make sense of the individual instruments that contribute to the whole.

It was also noticeable on the Godskitchen mix, but only just. Partly this is down to the relatively flat mixing where everything seems to be dumped in at 100%. What did stand out was the silver cable's ability to drive the leading edge of the beat and move the music on. On balance, the differences with this track were minimal.

With the silver cable music is tighter, better controlled but still has separation and works better as a whole. The separation helps the texture of individual instruments stand out: on the Bruch Violin Concerto it was almost possible to hear the effect of rosin on the bow of the solo violin. There was a rich textured grainy effect on some of the lower notes that didn't stand out so much on the Sendstation combination.

Finally, having got bored of all the little clips music I was listening to in great detail, I decided to relax with a little Bruckner Motet. The silver cable shone through here: it clearly had control of the sopranos (something most conductors find tricky) where the Sendstation tended to lose grip on the high-note crescendos.

The greatest test of any equipment is always whether you end up listening to the music or the kit. I found that that every so often I became immersed in the music and stopped listening to the cable. It was always the silver cable that was plugged in. The trouble with this, of course, is that when you stop listening to the hi-fi it becomes a little difficult to review it afterwards..

Conclusions? I've got a few. The dedicated line-out to 1/8 is a very good sonic option. I haven't heard the Turbo dock, but the hooster cable has two fewer connectors to get in the way of the signal path. I reckon the sound would be very similar. The hooster was also customised to my exact spec (short length, double strain relief).

The Sendstation is handy - you can charge the ipod through it, the sound is good and it comes with added value bits. It loses out to the silver connector in sound, but only just, and not by nearly as much as I expected.

Furthermore, in my experience, copper and silver are like chalk and cheese to electrostatic speakers and I'd expected it to be the same with the Stax set-up. It wasn't.

If there is any change after a few weeks of burn-in I'll let you know.

(As a small note, the headphone out wasn't really in the running: this was tested with the Sendstation only. The dynamics were constrained and the sound a bit tinnier).

But my first words were about the small margin of difference between the two cables under review here and I wonder whether there is much one can do to maxmise a line-out, given the muck in the way of the signal path (see vinnie rossi's comments on this elsewhere on the site).

So instead of fantasising about naked women climbing every obstacle to get at my body I find my dreams tending towards a redwine imod. And don't call me weird (wired?). After all, you logged onto this site too..

> you are testing and comparing cables, with an iPod as a source?
> What format, compression of the files? What version of iPod?

Good point - should have mentioned them:
5G 30g with apple lossless

>And you are using a portable Stax (SRM001-setup?) with noisy power

Noisy is comparative: there is a hum at a very low frequency. This was only audible on the Bruckner Motets, and only when the choir stopped singing. I think it is a 50hz or so mains hum and I was able to earth the silver cable by touching it (not a practical solution!). Couldn't do this with the sendstation.

I did also reconfirm everything I listened to using the battery only. I still felt the sound was better with the mains transformer.

> And you even yourself believe the sound is better with this noisy power-> supply than with ordinary batteries?

Yup!

>This still make you capable of comparing two such insignificant parts of >the signal-chain to each other?

I just did the review and it says what I think: it's for you to decide whether I'm cabable or not! :-)

As to cable being an insignificant part of the chain I think it can sometimes make a big difference, particularly between source and amplification, as can the type of connectors used. Difference does not necessarily mean better or worse either.

Sometimes there is a whole load of guff talked about cabling. However, I'm prepared to keep an open mind and see what I can hear. So to speak!

Perhaps I might chime in here with a few comments (nothing extensive). I also happen to be using the SendStation USB Line Out with the 5G 60GB into the Stax SRM-001/SR-001MK2 combination. At the moment I'm using an ordinary 10 Euro cable between the SendStation and the Stax. This will change as soon as I get my Black Diamond Reference from myo.
The Sendstation PocketDock/Stax combination provides (me with) a far more satisfying musical experience than that provided by the line out of the Universal Dock.
Although I have no problem with low frequency hum mentioned by Sniks7, I seem to prefer the sound of the Stax on batteries... it seems smoother and more defined.
I am quite looking forward to the arrival of the Black Diamond cable. I wonder if this will make a difference to the sound.

I wonder whether different cabling will make much odds with the stax: I'm not sure the energizer is good enough.

One of the main stax dealers in the UK has also suggested this.

There are rumours of a new portable amp made by someone on this forum. Now that might be interesting..

The Universal dock seems to have some minor problems with the sound in comparison to amplifying the headphone out at the correct volume or (same thing) my own small collection of aftermarket line-out options.

Actually I'm quite satisfied with my Stax setups (portable and non-portable). I'm just a bit curious as to whether or not the Diamond cable can be an improvement.

I think I might just have another go at amplifying the headphone out.

Kevin Gilmore is working on it. No reason why it shouldn't work with the SR-003 but as I understand it (and as I am hoping) it is intended to work with the wider range of 'full-size' Stax headphones (and presumably the HE90).


I've currently transported my O2's semi-permanently to where I'm working a lot, so a portable amp that's decent would actually be quite helpful.
