Although your request goes somewhat beyond of what I normally share in the public forum, I’ll bite…a little.
I have a graduate degree in EE and undergraduate in Applied Physics. I went to school in Boston in the mid 80’s. I worked for a number of years for the leading microelectronics company in Boston, - did linear circuit design, - DACs, A/D, op-amps, etc. These days I teach electronics and do lots of consulting and indulge in my hobbies. I also briefly worked for Bryston in the mid 90s. Nice company, but it was not for me.
My audio HT set-up is nearly all done by me on a DIY basis. To quote from my profile on htguide, - I have:
Projector:
Marquee 9500 Ultra front CRT projector with DVI input and internal 1080P capable scalar.
Speakers:
DIY 3-way Linkwitz-inspired dipole speaker in the front. Here is the picture of one front channel
2-way modified Carver Mark IV dipole in the rear. No center channel. DIY sealed sonotube subwoofer with two 15-inch Avalanche drivers, a la Tubezilla (thanks ThomasW). All use heavily modified DCX2496 active digital cross-over in combination with the DEQ2496.
Electronics:
DIY 200 and 400 Watt (4 Ohm) power amps all around. My amps are inspired by Bryston, but they have by far better electronics then even the modern Bryston SST amps. I purchased some older Bryston amps, because I really like the way they look. I gutted them to the core and heavily modified them. I updated output stage, introduced a more sophisticated feedback structure with no electrolytic caps, better transistors everywhere, better input balanced circuit, better stage current balancing and better thermal tracking.
My DVD player is older Sony 975. Meridian 568 controls it all.
My system is fully digital with power amps being the only analog component in the chain. I use balanced signal path.
Currently I am working on a better volume control for my system and still adjusting the subwoofer’s electronics. I am also looking at some superior power amps to introduce a more sophisticated balanced drive for the RD-75 (planer magnetic) sections of my front speakers. The HD-DVD/Blue Ray player is also in the works.
Well, I hope that does it…
Regards,
Victor
