Actually I had a series cap at mid/tweet amp (Hovland 0.022) and it seemed to sound better. I'm in transition process and Aleph is only temporary. My new amp will probably have input cap as well. Although it's still a tradeoff since without cap a signal is more pure, but there is more strain on midwoofers. Those Triangles are pretty much full range drivers and they seem to be OK when driving full range. I will have to make some sonic comparisons.
Peter,
Your system look great. You are the consummate DIY'er. When are you going to build the other speaker?
(Just kidding).
I haven't heard or looked closely at the Wilson's, although I hear nothing but good things about them. Do they use the open baffle arrangement as well?
(After Dave's post)
What keeps the rear radiation from canceling the front radiation in the bass region?
I posted after Dave's question, but I'm still "baffled" (excuse me) about the 15" bass cancellation.

I don't know about WAMM but the other Wilsons are not open baffle.
Usually cancellation is taken care by electrical circuit which compensates for that. I didn't need that in my design. Why I'm not really shure, maybe it slope pedestal (which is filled with sand BTW) or maybe it's room response. They go pretty flat to 25Hz, I was always thinking about active correction, but didn't get to it yet.

My system is more like an organized collection of Audio parts and equipment. More then 25 years later, it's still in a state of flux.

None of my kit is modified as yet and none of it is DIY either, but since I started posting on DIYaudio I've been undertaking a degree in electronics that should be wrapped up within the next few months (I am into DIY - I just don't get the time!).
Hopefully then I will get the time to finally finish my biamped P3A project that I started before uni almost 4 years ago! (or design my own amp from scratch now I can).
Ok so here's the system at present:
Denon DVD2900 DVD player,
Denon AVC-A11SR surround amp,
B&W 601-S3 fronts
B&W 601-S3 rears
B&W LCR60 center
Sony 24" CRT TV - quite old, but I've kept it for the fact that nothing I have seen at any reasonable price has even come close until the new wave of HD plasmas has come out here in the UK over the past year.
To my eyes/ears it's a pretty good system - although I'll be biamping when I get round to it and getting a decent plasma to top it off.
I'm also hoping to design/build some speakers based on dipoles (but with a twist) - again if I get the time!

Since about 1998 this has been my system:
VPI HW-19 TT with MKIII platter, numerous small mods to reduce resonance (lead sheeting, springs removed, etc.) with Shure V15VMR cartridge and Sumiko Primier FT-3 arm.
Denon DVD/SACD player, unmodified. Sounds decent as is, but I'm sure it could sound better.
YBA Integre DT integrated amp. Stock unit, very nice sounding.
DIY speakers, 2-way, suspension, using an Audax 8" woofer and Morel 1" tweeter, with home-designed and built cabinets, with interesting crossovers using principals from Ray Kimber.
It's a pretty straightforward system, really. It could probably benefit from more power (the VBA is only 50wpc) and the speakers are probably not perfect. But generally I'm pretty satisfied with it. Right now I'm working on cleaning my LP collection and making some CD transfers.
