I got up early this morning, and after drinking a cup of coffee to clear the mental cobwebs, I decided it would be a good time to try the tinned-copper Duelund bypass capacitors that Frederik sent me in my Altec A5 Voice of the Theatre loudspeakers' crossovers.

You can see them in the center of the photo above, in two positions, C2 and C3, in the HF portion of the crossover.

Modified Hiraga-style crossover.

I put on a couple of albums, Chet Atkins' and Les Paul's Chester & Lester, and Bill Frisell's, Marc Ribot's, and Tim Sparks' Masada Guitars.

All I can say is, "Wow!"

I am rapidly becoming convinced that Duelund tinned-copper capacitors are the "voice of God" when it comes to capacitors, at least that's how they've performed in the three different applications I've tried them in.

Chester & Lester and Masada Guitars were completely transformed, and sounded so freakin' real that I still can't quite believe what I'm hearing.

You know that new string articulation you get right after you put new strings on your guitar? That's there is spades, with the nuance of tone, the sense of touch on the strings, the timbral realness, the articulation, all being there in abundance.

There's astonishing transparency with lots of natural sounding detail, a huge increase in presence and sense of space, oodles of nuance of tone, gorgeous timbral textures, dramatic dynamics, that really makes Masada Guitars and Chester & Lester exciting to listen to.

I am astonished these four little Duelund tinned-copper bypass caps had such a dramatic effect on my A5 VOTT's performance.

It's the same sort of thing I heard when I put the prototype Duelund CAST 0.22 uF tinned-copper caps in my vintage McIntosh MX110Z tuner-preamplifier, or when I tried the 0.22 uF prototypes in my crossovers back when.

I am coming to the conclusion that the Duelund Sn-Cu capacitors are 'next level' capacitors, as they've so dramatically outperformed anything else new or old I've come across.

I can only imagine what a set of crossovers constructed entirely out of Duelund tinned-copper capacitors would sound like!

I'll have more to say about these as I get some more listening time in on these, but for now it's two thumbs up!

As always, thanks for stopping by, and may the tone be with you!
