How do you think these would go in the output stage of your SPDIF dac? Maybe we could set up some sort of test - it adds a bit to the price but it looks to my inexperienced eye like the case for your unit might be able to accomodate them.

Incidently, what is the output impedence of your dac?
Burson's product have been interested me for a while, but I never had the chance to try them. I'd love to hear people's comment on how it compares to the current crop of OP amps.

One issue that always concerns me with discrete parts is the device matching. IC OP amps don't need that because they could get naturally matched devices by careful design and being all on the same die. which is why National Semi's been announcing a bunch of insanely high performance OP Amps.

With that said, I am not trying to say that Burson's stuff is good or bad, but just something to keep in mind when considering discrete parts. I personally would love to see some kind of comparison between Burson's discrete op-amps and some of today's more advanced IC OP amps. Both measurement and listening test are important to me, as the device is for someone to enjoy, but measurement can sometimes pick up where people might have missed at first glance.

At first glance tho, I worry if it will fit into the case of DA-131, since it does not have a very tall case, you might want to double check with the actual unit in hand. from calculation, it will give you about 45mm of room... which might be a tight squeeze.


The output impedance is about 200 Ohm, very lot output impedance courtesy of BurrBrown's OP

I was just wondering about that, order received, and will ship it ASAP (as soon as we get a proper power plug adapter tomorrow, we will ship it. )

That's good news, any idea on shipping times?

We use international EMS shipping, which is almost as fast as Fedex/UPS but costs a lot less. It should arrive in about 3~4 days after shipping.

A huge typhoon hit us on friday and caused a delay in sending out the parcel, it will be sent on Monday

It arrived today , in fine condition.
Hooked it up with my own power cable, in stat of the one supplied with the converter plug.

Instant recognition in XP.
First impression is that it sounds good, a lot better then my old Hercules Game Theater. Not as sweet as my cd-player, but I’ll give it some time.
I'll try to write a more complete report after I had some time to lissen to it more.

Do remember to play it at max volume in XP (XP's volume setup will automatically default to 1/2 volume, which degrades sound quality).

Turn in up and you will feel it "open up" instantly.

Same here... Cankin, you should start the official KECES DA-131 thread in the Dedicated Source Components sub-forum.
