    Chameleon DAC listening and modifications

    Long gone. Benchmark DAC3 HGC now, which sounds better to me.

    Benchmark DAC1 HDR

    As above, I want the multiple inputs.  Or even a DAC2 HGC, if the price is right.

    Chameleon DAC listening and modifications

    The usual procedure is to remove the Wima caps and replace with your choice; I now use a pair of 6uF Russian KBG PIO caps outside the box (they are BIG) and Teflon bypass caps inside, but you can leave the Wimas; long burn in time for some caps.  Remove the large SMD caps and replace with...

    Chameleon DAC listening and modifications

    Hi, yes, all the solder pads parallel the original caps.  And from memory, I am pretty certain the SMD chip caps parallel each other, so any new ones will parallel them. If you look through this thread all will be explained.

    Chameleon DAC listening and modifications

    My Chameleon has arrived at long last! Now I have to go back and re-read the whole thread. Damn! Anyway, I have done the yellow wire mod, and have run in the dac for 40 mins. Is it ready yet? Seriously though, Blackgate FKs are pretty hard/expensive to get, would it be worth trying 10uf...

    Chameleon DAC listening and modifications

    The problem is cost. I can't afford another DC-30W. It's a Chameleon on it's own or nothing!

    Chameleon DAC listening and modifications

    I am about to order a Chameleon, as they are at last on sale again, but use my DC-30W from the Valab DAC. Is anyone using this older PSU still, as Michael says it is designed for 8 chips, not 16. Has anyone had insurmountable problems re-using it? I can't afford to buy another at the moment, but...

    Valab NOS DAC - subjective listening and modifications

    I have been using 330R Shinkoh tants as I/V resistors for several months, but had too much sibilance. I put in a pair of Takman metal films 2 days ago, and the sibilance is tamed. I don't know how they will age, though. Pat, I bought the Valab solid silver digital cable (sorry for waiting so...

    I think if you cut the + link, as Michael at teradak shows on his blog, then you can leave the regs. in.

    Installed the Lundahl LL1572. My wife (who is not seduced by new toys) immediately said how Leonard Cohen's voice has deepened over the years (we were playing 10 New Songs from 2001,a familiar album, and we have just been to Venice to see him perform). I noticed a reduction in sibilance, which...

    Thanks Bill, But that is $135 shipped, (with VH's cheapest plugs) and I have to make them up. The point was to try to save money!

    Valab NOS DAC - subjective listening and modifications

    A sideways question; has anyone tried Valab's solid core digital cable? The one Kevin sells for $80. I can't afford to keep buying lots of different cables, the DC-30, the Lundahl, and various caps have nearly cleaned me out. Richard.

    Valab Dac-First Impressions

    So, If I don't want to change resistors, I get the LL1572, and just solder it in? Please?

    Valab NOS DAC - subjective listening and modifications

    Does anyone know where to get the PE 65612 transformer in the UK? Mouser charge £12 to ship to the UK, but they only cost £3 each! If other people want them, I could buy a few, post them on, and split the total postage cost equally. Or if someone else wants to do it, I would pay for 2. Bill...

    Valab NOS DAC - subjective listening and modifications

    A thought. I sent back some AN tantalum resistors, as Bill pointed out they are "slightly" magnetic, and replaced them with 1W Shinkohs. The ferrite beads are also magnetic, but I will be bypassing them anyway. Has anyone noticed, and does it matter, that all the PCB and socket mounting screws...

    Valab NOS DAC - subjective listening and modifications

    Lindsay, Over-rating current is no problem, over-voltage could be. However, in this set-up, your toroid should be OK, the original tranny is rated 2x9 @240v, the toroid 2x9 @230, =2x9.4 @240. There are questions about toroid sound quality, though.

    Is the Blackgates' long burn-in time noticeable when only the 220uF PSU cap is added. Or am I getting really anal?

    Valab NOS DAC - subjective listening and modifications

    Thanks again Pat, I'll stick with the Valab's output caps. I am so glad there are people with brains worth picking, and are prepared to let me pick them!

    Valab NOS DAC - subjective listening and modifications

    Output cap question. Using a Prometheus TVC instead of a pre -amp, do I need output caps at all?

    Valab NOS DAC - subjective listening and modifications

    Thanks Pat, I should have thought about the magnetics. What about polystyrenes as bypass caps , though? I get too tired these days to try things over and over again ( long hours and age don't mix well).
