Hi Mike He has a old pair of sennheiser hd470, they are 32ohm, i was thinking about a pair of koss portapro or senn px100 as well. He has a sony walkman cd portable player and listens mostly to rock and roll, doo wop, guitar type music etc. thanks pjc68 Hi Patrick, I just whipped my PX-100 and portapro's out and had a quick listen..... to my ears the portapro are your best bet for the music your dad listens to, they're bassy, boppy, musical and fun.... you really couldn't ask for more from a £50 amp / DAC and £20 pair of 'phones.... to be honest, you don't get a lot more from a £500 amp and £400 pair of headphones. Mike.

Hi Patrick, If you PM me your details I'll send you four rubber 3M stick on feet (I have sheets of them).... a lot cheaper than wooden feet (free) and they do a better job Mike.

Hi Mike, any update on how it fares with the HD600's? Do you really reckon this is over £200 worth of performance in such a tiny package???

Hi Mike, any update on how it fares with the HD600's? Do you really reckon this is over £200 worth of performance in such a tiny package??? Give me 10 minutes, I'll go and hook my HD-600 up to the NG-27.

OK..... I've got the HD-600 hooked up and the first thing I notice id I've got to turn the NG-27 up to 12 o' clock to get a half decent volume.... cranking her up to full volume gives about 50% of what the HD-600 would deliver powered by a BIG amp....
Unless you like your volume at ear bleeding levels the NG-27 / HD-600 combo is fine but nothing special... I, personally, wouldn't recommend it for use with the HD-600 as it doesn't have enough clout to drive them to their best abilities.
Mike.

Hmm...
DAC chip (PCM1793) seem OK... SPDIF receiver (DIR9001) is excellent - you should have better sound through SPDIF than USB input - which is pretty common 16/48 jittery implementation.
If headamp section is anywhere near Solo they are referring to (GS Solo I presume) - this DAC/headamp is a steal.
If you jump at it - please refer back.

Thanks for the reply FD.
It's the USB that would get most usage, should I then look elsewhere?

It sounds relatively good until you compare it with something that has low jitter. Something like Musiland Monitor 01 USD ($75-ish) or TaraLab TeraLink-X ($60-ish). Both eBay.

You Bloody snobs!
For "kick ass" performance on a budget you can't beat this amp IMO.....
Let's keep all this in persepective guys ;D

FauDrei and Alex, Thanks for the replies, I've scrubbed that idea. I was hoping for a compact, one box solution in the same vein as the NG27 of this thread. Therefore, needing USB in with 'phones and/or line out. (ie full USB DAC) The Musiland and TaraLab that FauDrei kindly pointed out handle just the USB to standard digital out (as good as they may be). Anything recommendable out there? (on a budget ) EDIT, wrote the above just behind Mikes post. Not ignoring you Mike, just seeing if those already into digital from laptop (hence USB) had any insight...

I've Finally got this little guy up and running proper (a hard drive full of lossless Jazz and other goodies thanks to Miguel).... I've dedicated the Sennheiser HD25/1 to this little PC based system. You REALLY couldn't ask for more from a PC based headphone setup and, for the price, you certainly cannot complain. This little setup takes me away from my CD based rig and, believe me, I'm in no hurry to go back to it. I never thought I'd say that

I think I'll experiment with opamps in this little beauty at the weekend

Almost 2am and I can't drag myself away from the NG27.... the music it's making is absolutely beautiful. This little puppy and the whole "computer as source" thing have really got my juices flowing again Time to roll out the opamps!

Next thing you'll be thinking sqeezebox, so you can wirless stream the music, and then play through the squeezebox > DAC > head amp .. anywhere in the house instead of being forced to sit at the PC to listen..

Wouldn't touch a Squeezbox with a bargepole mate.... I want an "easy" life and don't want to be spending my time trying to get a Squeezbox to work ;D Anyways, I digress.... Had another look under the bonnet and noticed there was provision for more capacitance..... "stock" is 16V /4700uF... I've added another 16V / 2200uF into the spare "bay" so now we've got 6900uF... I also removed the stock OPA2134 opamp and have been rolling in chips all afternoon (the best available from TI, National, AD etc.) my favourite, so far, is the good old AD8620..... I'll go into more "depth" when, and if, anyone is interested Mike.

Yeah, me. Go for it. This looks like the little beastie for me too. My computer music needs are quite basic at the mo. So the minimal outlay plus a bit of tweaking sounds like just the ticket.

Chris Chris A good outboard 12V regulated supply could be an interesting way to go. You could even start off with a 12VAC plugpack, and fit a 7812 regulator and a handful of other components on a bit of perfboard inside a small plastic Jiffy box.(4 x 1N4002 /4004 diodes, a 2,200uF 25V capacitor for filtering, and a 100uF 25V capacitor at the output of the 7812) Alex

Looks nice, Mike. Don't forget to stack the buffers, as it was a favourite on the Pimeta. Pimeta TweaksI've seen pictures of them stacked 8 high, but I'm sure you're more sensible than that ;D

Chris Chris, This is about as simple as it gets! Simply connect the USB cable to your computer and you're up and running.... it's, by far, my best audio purchase for many a long while..... a few weeks ago I was sitting staring at a screen, I now have an itunes library (and adding to it every day) and the sound quality is absolutely top class. This little puppy is excellent "as is" with the stock OPA2134 opamp but the AD8620 takes it to another level (to my ears)..... It compares extremely well to, let's say, a mid priced CD player + X-Can v2 amp.... I'm actually amazed at JUST how good PC based audio sounds these days.... I import my CD's using Apple lossless (each CD takes about 3 minutes to import) and, bugger me, I cannot tell the difference! For the money, the NG27 is a "serious bit of kit".... no need to fart about with soundcards, just plug her in and she does the business.... a DAC and amp (and a bloody GOOD amp at that!) I always judge gear with my ears and my ears tell me I won't be "upgrading" this little beauty for many a long year. The build quality is the best I have yet seen, top quality components on top quality PCB.... there is very little lacking in this package! Will mentioned the possibility of adding more buffers (stacking them) and, yes, this would be easy to do (if you're good with a soldering iron)..... I'll give it a go and see if it reaps rewards in the SQ dept. but, as I have already said, there's not much "lacking" in the NG27.... it has been extremely well executed with SQ being paramount. Sandy mentions a regulated PSU.... another possibility though, again, my ears are pretty happy with what they are being fed via the switched mode PSU and I'm not sure I WANT a PSU that is 4 times the size of the combined amp / DAC cluttering up my desktop..... I will try one of my Pinkie V PSU's and report back on the SQ gains (if any).... So far the two simple mods I have performed suit my ears nicely..... AD8620 + an extra 2200uF capacitor..... I'm going to remove the reverse polarity protection diode tomorrow and jumper over with a radial ferrite inductor..... this should see a slight increase in clarity if past experience is anything to go by. The aluminium knob has gone, I'm now a great advocate of "rubber / plastic" knobs.... I don't believe in touching anything metallic when I'm adjusting the volume and I also believe that metal knobs are another entry point for interference..... Anyways...... these 20 pence a pop splined socket jobs do the job nicely (push on) and fit perfectly .

That does it then. As soon as the Chinese folk come back to work from their national holiday I'll be snapping one of these up!
