Capacitor question


I have BAT VK-150se amps powering SF Amati Homage speakers. I replaced the stock BAT/Jensen POI caps with CuTF V-Caps. There is a lot more detail now, however, the sound is thinner, brighter and fatig

Before you change any cabling in your system you should look into upgrading the stock 24" Belden wire from XLR to PCB inside the VK150SE.
A recap will usually sound different at first. I remember when i recapped my preamp, i was disappointed. It sounded boring and lifeless, after a month or so it became a new machine.
Just wait for things to settle before making more trouble for yourself.

You need to run signal through the amp for several 100 hours before you can make any decision about the sound. It will be tilted up for some time.

Personally I would have gone for a Duelund Cast or VST as a replacement for the Jensen if you liked the character of the BAT, but wanted more BAT so to speak.
Hi Chad,
Which Duelund capacitor did you use and in what application(electronics or speakers)? Were the results what you expected and did you also use or consider the V-Cap Cu?

Hi charles1dad,

I used Duelund both as coupling caps in my tube amp and in the xover. I tried all the usual suspects Mundorf silver/gold/oil/ and the silver/oil, clarity cap ESAs and others. All good.

I was advised that the vcap had a slightly clinical presentation if not a touch Hifi. The Vcaps also take ages to burn in and sound good.

I liked the Mundorfs a lot. The silver/gold/oil being great if not a tad energetic in the highs. Lots of detail like the vcap but with some beauty space. They will sound forward and change about for a hundred hours or so then settle to a more balanced but still highly detailed sound.

The duelunds are just utterly complete. Straight from new. They sound natural and while detailed, the detail is not rammed down your throat. It has dimension image density and plenty of textural tone. Lovely and as they burn in they just get better. If you want real and not hyped it has to be duelund.

If you need more energy on top try some mundorf in the amps power supply. Try as bypasses if they will fit and keep duelunds in signal path.
