Just wanted to say hello to all the peoples in the DIYaudio forum... I have been building amps and digital stuff for a while now and this place is perfect. Lots of good information so far!! You guys will be seeing more of me in the future so I figured I might as well introduce. I am currently a grad student at SDSU studying electrical engineering with my main interest being anything audio related, including DSP methods, DAC, and ADC design.
Hope everyone is well,
Hope everyone is well,
Since this is a DIY forum, and my sound system is DIY, thought I might mention what it is.
CD player: Marantz 3100 (I hate it)
TT: Technics 1200MKII, Ortofon Concord w/Pro-S stylus
Preamp: custom DIY
- Phono, line, and SPDIF input, auto switching
- 24 bit, 96KHz delta-sigma DAC
- 4 band parametric shelving EQ
- Two way Linkwitz Riley aligned crossover, with swappable frequency modules.
Amp: custom DIY
- 100 watts X 4 configured in a biamped arrangement
- MJ21194 pwr-bjt's used in the OPS with 750VA toroid
with four 20,000uf cap banks
- No VI limiting or protection relays (yes, I know)
Speakers: modified Polk RT25i's
- Crossovers removed for bi-amping and a coke can sized Solen film cap added on the tweet
- Woofers replaced with Daytons (I'm cheap) since my amp ruined one of the
originals due to a cold solder in the amp [let the smoke out of the speaker... fire alarm went off
]
Sub: DIY
- Dayton Titanic 10 in a 2.8 cu. ft. slot ported enclosure tuned to 27 Hz
- 300 watt subwoofer amp board from ESP with 300VA toroid
- Thermally controlled fans ( for the occasional party )
I wouldn't consider myself an audiophile... I guess more of an "audiopile"... I will post a pic of the pile soon.
