We did design our own custom capacitors that are used in the LS 36.5 as well as our phono stages. I had been using the Sonicap capacitors and they are excellent, but I wanted the very best that we could get and ultimately settled on designing our own. I chose oil-impregnated poly as the dialectric type for the larger values - 1.0uf and larger - and pure teflon film and copper foil for the smaller value signal path capacitors. They are quite simply better than ANY capacitors available on the market and the improvement is evident in our new MWI products.
We are also considering offering a full MWI cap upgrade for the 9.0SE preamp for $500. Please reply if interested. This will be available as an upgrade through all MWI dealers.
I cannot say that the new capacitors necessarily increase the frequency response of the 9.0SE, as it is already very good, but the tonality and sonic neutrality of the new capacitors is where the benefit lies.
We are redesigning our website and when this is done, we will be adding a page for the MWI caps, with pricing, etc. for DIY use. We do have them available right now in the following values:
4.7uf-400V Metalized oil-impregnated poly.
1.0uf-400V Metalized oil-impregnated poly.
.1uf-400V Metalized oil-impregnated poly.
.22uf-400 Teflon film/foil.
.1uf-400V Teflon film/foil.
.01uf-400V Teflon film/foil.
Please email for pricing. OEM inquiries welcome.
Thanks,
