Yamamoto YDA-01 DAC

devilboy,
Off the top of my head I don’t remember and I’m not at home now. I ’think’ a short length 3 amp slow blow. There should be a spare fuse at the IEC site on the rear of the DAC. It has been a number of years ago when I installed a SR black fuse that’s still in there. It was clearly an improvement.

I’d get the orange fuse and I believe that you will be very pleased. Install it , listen and then reinstall in the other direction. One direction is nearly always better sounding than the other. Upgrade fuses as you know are a controversial topic. In my experience with numerous components they are a definite improvement.

Audiogon member david_ten recently placed some SR Orange fuses in some of his components and says they're fantastic!  I trust David's ears/judgement. He has a superb audio system that reveals all.

@charles1dad  thanks Charles. I appreciate the help and I'll keep you posted.

Btw... This Yamamoto is amazing. You know when you get that component in your system and you realize that you've listened to a few songs and you haven't critiqued or analyzed anything? You're just listening to music?  This is the first DAC to do that for me, but I'm sure you knew that.

devilboy,
I know precisely what you mean. The Yamamoto DAC has the same affect in my system as when I got my 300b SET amplifier.  Immediately it was apparent that the music listening became more natural, realistic and undeniably more emotionally involving.

As you note, no thought to analyze or critique various audiophile sonic parameters.  The overwhelming desire was simply listening to the music and connecting with the musicians and performers. After all these years that has not changed even a small bit.

Hi guys,
I took Charles advice and put in the Duelund Cast caps. The difference is not subtle. But also after a while, I was thinking that maybe the sound was a bit too "pure".  So I added/bypassed the Duelunds with 0.22uF Jupiter Condenser Red Astron caps.

These caps have some tin in the windings, and have a sound I've really loved, giving beautiful space and naturalness also in my VAC Standard LE preamp. I think the Jupiters really made the icing to the awesome Duelunds in my Yamamoto.
And it also turned out that later Duelund themselves made a Cast copper/tin plated cap, which Tony at Humble Homemade Hifi considered even better than the pure copper version.

I'm really loving the music at home - and friends go "wow" and are a bit jealous.  ;)
