Hi All,

My son wants to change all of the electrolytic capacitors in his set of LV1020's, and he wants me to change mine as well. Has anyone in the Forum made these changes, and if so, have you noticed a significant improvement in sound quality? I personally can't imagine that my 1020's could sound any better than they do now, but he thinks they will. I would greatly appreciate any suggestions for the best quality brands for the replacement. If you also have a list of the capacitors that were replaced, that would be great. Thanks !!

All the best,
Ron

Hello Ron,

from my point of view, changing all caps is nonsense. They are used 1. for galvanic separation between the amplifier stages - a loss of capacity will result in a loss of low frequency, 2. for filtering of hum caused by the 50 Hz net frequency.

A lost of 50 % of the capacity will cause 1. a maximal loss at 20 Hz of 3 dB - compare this to they level chance possible by the bass-regulator of your pre amp (that also meens max. loss of 1,5 dB at 40 Hz), 2. a increase of hum of 3 dB - that is not much! But most time you can expact a little loss of capacity or a total defect, but not a lost of 50 % - so if your LVs sound well, there is no need to change all capacitors.

I also own some much older devices than LV 1020 and they work well. Of cause I had to chance one or two caps because they were totally defect.


Yours
DerLange

Audio grade capacitor (Elna, Black Gate) sounds better than all over. Theses devices are designed for high end audio. They have particular internal structure, which seem to be very important for audio render. While, very low ESR doesn’t seem to be quality argument. Elna gives detail and pictures about internal structure (Silk Fiber)
NOT for Power supply .

So soon I'll order ELNA (Elna Silmic II) this capacitors need 100 hours burning time.
I will surely answer as Elna Silmic II sound, now on LV1020 i got are new condensers but different like Nichcon and without names.

This speakers can sounding like real High End.

What can sound better than LV 1020 ? Two pairs of LV1020. :D
