very generous of you vapman.
Big thumbs up.
 
Did you at least keep brief notes?
Or is it just a "get off the stage" like the old Gong Show on tv?
 
 
 Curious on the 2132P, should be similar to your 2134.
Not tried the 2132P 's I have here yet.

  Anyone know which is better sounding , Elna Cerafine black/gold or Elna Robe Silmic II(2nd gen) purple/red colour for signal path or any suggestions.

The black/gold being the newer model.
I can't recall exactly but I think TRANCE had a post about the differences ( maybe ), which may be very slight.

I did take notes on each 
I paid for them so I made sure to get my moneys worth by at least making sure I wouldn't have to revisit them  haha.

^ and that doesn't mean that someone else might not enjoy that exact sound either
 
=so people get on it an offer like that won't last long

My walnut FINALLY arrived today. The box included the walnut and a usb cable. The walnut seems to be made well. No connector issues or weird noises or anything.

Only 3-4 hours of burn-in so far. It's still early, but it sounds nice... lively. The noise floor has quieted down already, so that's a promising development. Comparing to my mid-level Yamaha 2-channel gear, the walnut is pretty dark sounding. Highs are noticeably more extended and detailed through the home hi-fi. We'll see how the sound signature evolves after more burn.

To be fair, the Yamaha gear costs 15 - 20 times more than the walnut. Also, Yamaha gear can lean towards the "bright" end of the sound spectrum.

I would stick with silmic II personally. Also the Japan made silmic II are actually brown/white, the silmic II in Walnut are black/gold or purple depending on batch.
 
The black/gold Silmic II are made in Thailand, not sure on the purple, but I know the purple silmic II are smaller in size and rated lower in ripple current at each uF/V (bad thing for resolution, but has a warmer sound).
 
So naturally my preference in sound for the Silmic II in descending order is brown/white > black/gold > purple.

It would be interesting to hear someone put OPA2227 in?

The chip for some reason ends up being contraversal with some liking it and some not.

I have heard it described as a more refined overall OPA2134. Can't say for sure either way. 2134 was too bass light for my tastes anyway. funny cause some guys describe the 2134 as bass bloated. on what universe?!

I'm enjoying it in my JDS c421 where it was offered optional.

Same reviews where some call it warm and others cold and detailed.


This confusion only means we must try it. It will be the first operational amp chip I buy.

my bad there I thought  their post was asking about the Cerafines only ( reds vs newer blacks ). I need to read more carefully

 

[deygun]

Best combination so far..

 

[waynes world]

Been rocking out with the original VE Zen paired with the Walnut lately and it's a great combination

I'm still using the Burson V5i in my Walnut and like it a lot. Will shift back to the stock op amp soon now and see how I feel about it.

 
Cool! I can't wait to try that combo myself.
 
My first Walnut got trapped in Taobao non-English shipping agent hell, but I somehow managed to get it shipped back to the seller and get a refund. 
 
I ordered my 2nd Walnut off of ebay (like I should have done in the 1st place), and fortunately it just barely escaped China before the new year festivities got fully under way. So only 1 more month wait lol!

I've never had any experienced about opamp rolling before. So I tried to look some opamp on our broken stereo receiver and CD player. I found one its JRC4458, de-solder it and installed on walnut and it sounds identical to the walnut's stock opamp but with more bass punch. Any thoughts of this opamp I found?

THANKYOU for posting about this opamp. A big thumbs up.
 
( JRC4558D )
 
Love it so far.
Absolutely gorgeous sounding.
 
OH WAIT I got a 4558 not a 4458 like you have =wow. Crazy.
 
Now I need to look at some spec sheets see how close they are I suppose. For kicks.
 
I guess mistakes happen for a reason sometimes.
