Oh THAT one. It is still on the card. I have the first prototype PCB in my office waiting for me to mount the components on it and then try it out for any final amendments.
But to be honest with you, I have a pile of designs lying about half or completely abandoned. The Caiman II has undergone two redesigns, but I was not happy with the projected bill of material cost, so I am back to the drawing board with that one. I might post some pics of the two rejected prototypes.
Due to the current and expected economic downturn I am trying to finish off the most urgent requests for new products. But wait till you hear the headamp on the Bushmaster. It is better than the Caiman version. The dedicated headamp is a couple of steps up from that.

Stanley, how dare you tease us?

I have only three words to say - pre and order

Me please

Ta,

I am being cautious for many reasons.
The Bushmaster is a minor statement DAC with some specs that knowledgeable DAC designers will want to have a peak at. But specs are one thing. Price has to be sensible and near impossible for anyone else to try to compete against.

Projects on the back burner ... I know that feeling!
Well maybe I buy somthing cheap whilst I wait for you to get your arse in gear

hehe

Any thoughts on my minor digitalness issue...?
An opamp I might try? Etc?
Sorry to thread high jack?
It wouldn't be an issue if it wasn't going to be in a system that the only digital source is spotify ...

You'll have to refresh my memory on that, or execute a reboot

What, you can't remember every issue every customer has ever had?? I'm disappointed

Yeah, sorry ...
Basically, when listening to spotify and some less well recorded music even from higher res stuff, with my grado sr325's I get a bit to much detail in the highs that emphasises the "digitalness"
I know the grados are supper detailed in this area ... But tey sound fine with most good well recorded cd quality stuff ... I just feel if I could take an edge off I would gain more than I would loose ... Ya with me?

If you are a handy soldering iron operator, change the two yellow 4.7nF caps on the Gator for say 3.3nF or even 2.2nF. Also use an AD826 opamp if yo aren't already.

That sounds like somthing I could do ...
I don't suppose you have a couple of appropriate caps I could p'chase p'chance

These things don't easily come to hand in my household

I shall have a look, but don't hold your breath. They are not values that I have fitted to anything.
