I am so impressed with this unit I just had to write a mini review :)

Since having to send my CD transport back to Cyrus (again) for fixing I've been using my Wadia 170i in system 1 which reaffirmed how good this is after the Audiocom signature upgrade. System 2 has my Quad 67 Cd player which after the output mod is pretty darn good but I have no way of playing my iTunes stuff through this system which as it's in the study with my iMac and stuff is a bit limiting.

I'd seen these Chord Bluetooth DACs reviewed (mainly positive with a few not so impressed) but they always seemed a bit pricey although from a technical point of view they fit my requirements perfectly. Anyway, one came up on that well known auction site at a very reasonable price so I snapped it up - it's in mint condition so I'm well pleased.

Hooked everything up earlier today with no issues at all.

First I used the USB input streaming iTunes from my Samsung Netbook. All worked first time (nice) and SQ was OK but not startling - perfectly good for background music but not up to scratch for a serious evening's listening - the Quad 67 was much preferable - pretty much what I expected really so no worries.

Then I setup the Bluetooth connection via my iMac - in all honesty not expecting much more as I reckoned the the "wireless" can't be as good as the wired. How wrong was I :stalks: SQ was just so much better than the USB - I reckon the better sound card in the iMac must be responsible here.

You'll see from the photies I've hooked the DAC up to my amp via an input selector so I can switch between the DAC and the CD player - the Quad 33 has very limited inputs and I'm using them all. Now before we get all purist the selector switch has been totally rewired with quality hook-up wire, a really good 2 pole, 5-way preamp selector switch from HiFi collective and high quality RCA sockets. Interconnects are custom 20cm length pairs G1000HD courtesy of Mark Grant. I've previously listened to the CD player direct and through the selector and couldn't tell any difference. BTW, it's not an Audi Origami unit - the decal hides a scratch :eyebrows:

Anyhow, on all the tracks I've played syncing iTunes to the CD I can not tell the difference. The iTunes files are Apple Lossless ripped from the same CD's. The Bluetooth is just as good as the CD in all areas - :) Not bad eh - gives me more choice etc etc - money well spent and all that - happy camper.

Well - it got better! I also bought a Russ Andrews GemPak external PSU to replace the standard Wallwart one which the initial listening was done with.

With the GemPak PSU the SQ just went up several notches - it's better than the CD player !:eek: There is a delicacy and finesse to Einaudi's piano, more authority, slam and attack on Springsteen's Wrecking Ball. I'd hesitate to say there is more detail but imaging is more focused and stable and the whole presentation is simply "better". On Gustavo Santaolla's Motorcycle Diaries the guitar and drum work has so much more attack and immediacy - with an impression of more space and air around the instruments. I guess this must now come down to the superior DAC in the Chordette than in the Quad. But this is Bluetooth not hardwire.

Bottom line is I am streaming music from iTunes on the iMac to my Quad 33/303 JR149's (old fuddy duddy stuff) via a Bluetooth DAC and the SQ is just stunning - so very pleased.

I also think it looks the muts nuts.

I've also got a Sony Bluetooth dongle to connect my classic iPod but it's still in the box.

:cool:

A couple of my friends have the same DAC - neither has tried the USB connection, as it was bought on the merits of the Bluetooth streaming capability alone.
And it sounds great doing exactly that.

The sound quality of your iMac's soundcard is of absolutely no significance whatsoever - it's being bypassed ;)

Just as a matter of interest Steve, what was the fault with your Cyrus CD? I used to be a big Mission/Cyrus fan, but their build quality is not what it used to be.

Hi Tim
Darn thing keeps skipping tracks and occasionally won't eject disc.
The skipping was getting beyond a joke and happened so often I just lost all enjoyment in listening as I was just waiting for it to happen. Wasn't down to "bad" discs as I could go back to the exact track time and it wouldn't skip second time. I sent it back to Cyrus last year - took over 1 month to come back and to be honest was just as bad. Sent it back again last week - not holding my breath for its return anytime soon - think I'll move it on along with the PSxR when it comes back "freshly serviced by Cyrus".

Reading other forums it seems this is a common issue with the CD XT se. I never had any probs with my Cyrus dad3Q or CD8 - in all honesty I thin the dad3Q was a stunning unit - wish I'd never sold it.

. . . darn thing keeps skipping tracks and occasionally won't eject disc.
That's what I thought you were going to say, but didn't want to prompt. About 18 months to 2 years ago I spent a day at a local dealer playing with 2 different Cyrus CD players. Both of the demo units wouldn't eject my discs about 20% of the time and some discs skipped, but in fairness not as often as the failed ejections - all the discs played perfectly at home. The second demo unit was fresh out of a sealed box, after I pointed out the issue to the dealer. I did some reading on-line after the demo and found similar reports - that was it for me and I never went any further with Cyrus. I used to have a PCMII which was great and I wish I hadn't sold it, it would have been ideal as a transport.

Good news about the Chord DAC, file based audio for you then is it ;)

EDIT: My first real speakers were JR149's, I shouldn't have sold them either :doh:

I'm with Tim on this one - welcome to the modern world :eyebrows:

Thing is, with the Chordette in harness you can share your DAC (and system) with anyone who visits.
The last time I visited one of my friends who bought a Chordette I ended up playing files from my phone via Bluetooth to the Chordette and onwards.
They sounded superb too.

Mmm! not so sure about that.

I'm darned impressed with the SQ - exceeded my expectations although my Wadia 170i is also "better" than the CD and I can easily see myself junking the 2 CD players and using the Chordette and Wadia instead but vinyl is another matter ;)

I'm not going to get into the whole vinyl debate but I do prefer the sound it gives me (tonal quality really) and there is no doubt that the whole "ceremony" of playing vinyl (and the kit required) adds to the pleasure :mental: So the Technics and Thorens with all their attendent bits and pieces are definite keepers.

I'm waiting with great anticpation for the new stylus for my Garrott P77 to come from Expert Stylus Company so I can give that a whirl :wheniwasaboy:

Yep - just tried the Sony TMR-BT8iP Bluetooth transmitter with my iPods - SQ just as good as from the iMac :)

I must admit I’m a bit surprised.
http://www.chordelectronics.co.uk/files/Chordette%20Gem%20with%20apt-x.pdf
says nothing about the USB so it is probably a 16/48 adaptive mode implantation.
Not the best there is but at least one is able to send CD quality (16/44) to the DAC.
Bluetooth due to its limited bandwidth only allows for a high bitrate lossy compression.
If you have the GEM with APT-X you can get a slightly better quality over the Bluetooth but this requires a sender capable of APT-X.
This in general requires a separate dongle.
Wonder why an in principle bit perfect transmission (USB) sounds worse compared with lossy compression (SBC=512kb/s)

Beats me - but my ears do not deceive :trust:

The dongle is A2DP and sounds very good indeed.
