elna silmic ii sound bad??

Hi all, i have a 2225 model. Some time ago I changed almost all electrolytic capacitors with elna silmic ii, and it sounded great(even i didn't compare with the stocks caps, since i replaced the caps shortly after i got the marantz).

But there were a few caps i didn't change at first(in the pre-tone board), and i did it now. a couple of 1 uf 50V(close to the equalized signal that goes to the power amp board), a pair of 4.7 uf and a pair of 33 uf. I turn up the receiver and how it sounds? : a complete veiled sound, lost a lot of detail on the highs, the soundstage and ambience was bad too, even a lepai ta2020 which used to be kick-assed by the marantz it's sounding better now :(.

This is kind of normal with the elnas? they need some break-in time? How long would it be? I'm really tempted to put the old caps again, but i would like to know if i should wait a little longer. What are your experiences with the elnas? Thanks for any advice :p
 
They do need some break-in time in my experience, soundstage gets a lot better over time. According to one site which sells elnas it can take up to 40-100 hours depending on how large the caps are. I am no expert but i have read that 1uf caps are often low-noise caps and some advise to use film caps for 1uf instead of electrolytics.
 
Elnas Silmic is all I use in my recaps. Never had a problem. But they do need breakin time.

Use these and Nichicon FG with All my recapps.

Around 25hrs to open up...to 100hrs full steam ahead.

Ya didn't replace some NP/BP's with some polar caps did you.
 
Looks like the 1uf 50V are the L/R output and are supposed to be NP.

CE23 & CE24 1µf/50vdc N.P. on the PE01 Tone Amp CCA. That will definitely veil your audio..Sound like shit!

Elna "Silmic" bi-polar- 1µf/50volt

http://www.hndme.com/productcart/pc/viewPrd.asp?idproduct=2280&idcategory=198

or Nichicon "MUSE" ES series
http://www.mouser.com/ProductDetail...ArNe9LFxXmbQTq%2bxw7/ZKff02Ir4LBjs8PajZxh2vQ=

or use a film cap such as

Panasonic "stacked films" are popular as well.

i don´t have the schematic right now, but i think i replaced c19 and c20(both 1 uf electrolytic polar), c23 and c24 are the original non-polar(i didn´t replace them), so the change in sound it's not their fault.. in fact, i suppose you can't replace non-polar caps with polar ones, right?

i replaced a couple of 33 uf and 4.7 uf too, all polar electrolytics..

Double check your polarities of the caps installed so far.Don't rely on the PCB silkscreening.It is quite often wrong.
 
Caps blow up only if leakage current isn't limited by circuit resistance, and it's pretty well limited in most of the low-level circuits.
 
Replacing polarized with non polar (with the exception of film) would sound like crap too, right?

Really, "Elna Silmic II sounds bad", this is the first time I have heard (seen) anyone make that statement.

i replaced only the polar electrolytics with polar electrolytics.. and yeah, i suppose it's surpising but that's what i heard :scratch2:

interesting... because i have a couple of elna ii (polar) but i didn't risk to replace the non polar ones.. maybe if i use only elnas it will sound great again :lmao:
 
guess what! i was checking the caps, and then i realized that c19 and c20 (both stated as 33 uf in the schematics), were in fact 3.3 uf!(i realized when i looked the stock caps i had replaced). so i put a couple of panasonics ecg i had for comparison with the stock elnas.. don't sound bad, but i prefer the original elnas(but probably i would be changing them with new elnas!).

the sound isn´t veiled right now..that's the most noticeable thing. i suppose you have to check the shematics and compare to the actual parts on circuit ..:D
 
Sometimes the schematics aren't right. I always go by whats in there to begine with. Clad you found the problem.

anyway, given i still have a couple of 1uf polar elnas, would i have some benefit on replace the 1 uf non-polar with them (given it's suposedly safe in preamp circuit, )?

Never replace non-polarized capacitors with polarized capacitors.
