Caiman passive output mod revealed

Damn, Hi-Fi Collective only have a single 1.6uF ESA in stock and won't let you backorder.

Has anyone tried AuriCaps? Their 2.2uF 200V is sized 23 x 20mm and cost £12.43 each.

See my photo here, Roberto, even the 1uF ClarityCaps are big!

I personally DO NOT MIND small or HUGE capacitors. I DO NOT mind if I have to place them out of case as long as I am able to find perfect Sound Quality (for my ears and my system).
So any suggestions are welcome as long as the cost of caps is not silly.
Since I got my 7520 from repair I have not been closing case of my lovely Mr Beresford as well as burning in all those caps.

@MartinT
I love the way your Beresford is looking especially the passive Caps. What is your model of Beresford DAC? With what caps you have replaced the biggest power supply cap and is the SQ any better?

My present state of DAC (just some random home found caps)

It's a Caiman. I replaced the big electrolytic with a pair of 2.2uF Panasonic film caps, which fit nicely. My power supply is a SuperTeddy set for exactly 16V. SQ with the ST and film caps is really excellent, very low noise floor and fine detail with no harshness.

(for completion, the regulators are Dexa and all electrolytics are Elna Silmic II).

Martin,look here.AFAIK these are rebranded CC's.

The legs on my Rubycon 47uF 50V seems to thin. is it a problem?

They're improving nicely, Ali, but I don't quite have the subterranean bass of the Rubycons. My preamp's single-ended input impedance is 47k ohms. I'm going to order a couple of 1.6uF Clarity ESAs (the MRs are too big). I'll properly wrap them in foam to prevent vibration against the PCB rather than just use the foam pads I've stuck to the current ones.

Martin

Do you think the electrolytics sound bigger in the bass as it's less controlled and a bit boomy whereas the ESA's are a lot tighter and controlled so they sound smaller, you have the best bass extension to really tell. I think this to be the case though.

I do find the ClarityCaps very tight and tuneful in the bass, it's true, but the Rubycons were no slouches and also had good quality, but fuller bass.

I sense a slight increase in value may do it, so I'm looking out for 1.6uF or 2.2uF that will fit.

Thanks, Ali. Meanwhile, I have ordered a pair of 2.2uF AuriCaps as they will fit and I can compare them with the ClarityCaps. I would still like, ultimately, to desolder the 5-way op-amp board socket and solder the caps permanently in place.

Martin, have you compared the same 16 bit CD via the Caiman to the SACD disc playing via your Ayre to gauge the differences in detail etc? I'd be interested to know what up scaling and interpolation really does to the sound.

Cheers

As I just started to enjoy my passive mod and already ordered some caps for it, I think I will leave my Beresford in passive mode for good.

Now I want to upgrade regs for MuRata regs and need info which ones I should order?
I also understand that I only need one to upgrade if I do want to keep the passive mod in place.
So which one should be upgraded?
I know that this mod is somewhere on the forum, but I just want confirmation as which one to upgrade if I want only passive mod without opamp boards.
Or it is best to upgrade both MuRata regs if not too expensive?
Thank you
