And me? I`m just along for the ride. Lightstar Lightstar Lightstar!!!!!!! \:D/ \:D/ \:D/

I hope I live long enough to see them all built and running. Maybe we can use them as a interhouse house sound stage, everybody between our houses will know when we are listening to music.

I told Ray this the other night, and I thought it might be interesting for the rest of the crew to hear...

I honestly, never really looked into any of the Lightstar equipment at all... I always thought it was an albatross, the same as the CT-30x... a prototype that wouldn't be worth the scrap weight if anything ever happened to it.
I never paid any attention to anything with the Lightstar name on it. Honestly, I deliberately steered clear of anything I came a cross.
At CarverFest, Ray had his LS rig there, and again, I paid it no attention whatsoever...
After getting back, and listening to Ray's babbling about "Lightstar Lightstar Lightstar" I did a little research, and some reading... and talking to a few people that know WAY more than me, and started to learn just what was behind the Lightstar logo. Wish I had looked into it a little more before.
I have been told, (by 3 people I would NEVER question, OR expect to tell me this) that given the choice, that they would choose a Lightstar product over a Sunfire of equal power. Even the Preamp, They said the Lightstar was preferred over the Sunfire Reference Pre... NEVER would have expected that!!

Whatever you do in life will be insignificant, but it's very important that you do it... because nobody else will.

OBI56 & Tom, that's one of the offerings from Musical Fidelity.

Ok, back to your regularly scheduled program.
Political Correctness...defined

A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.



In a recent press conference, President Obama remarked, "If I had a city, it would look just like Detroit."

Hubba, hubba. It's almost like audio porn. ;)
In search of accurate reproduction of music. Real sound is my reference and while perfection may not be attainable? If I chase it, I might just catch excellence.

The best way to enjoy digital music reproduction is to never listen to a good analogue reproduction.

at any frequency or combination of frequencies between 20Hz and 20kHz.
* Input Impedance and Sensitivity
1 volt R.M.S. across 50kohms for 200 watts into 8 ohms on the unbalanced input.
(note: the impedance value can be adjusted to any value up to 1 megohm-consult the factory)
+/- 1 volt R.M.S. across +/- 70kohms for 200 watts into 8 ohms on the balanced input.
Input selector switch for balanced or unbalanced
* Frequency response and power bandwidth at rated power
8 ohms - better than +/- .2 dB 20Hz to 20kHz
4 ohms - better than +/- .3 dB 20Hz to 20kHz
* Stability
100 % stable into any load angle 0 to 90 degrees,
capacitive or inductive, regardless of waveshape
* Damping factor
Greater than 250 at 20Hz
* Noise
Better than -120dB relative to full rated power

Protection Power switch/circuit breaker 4 DC power supply fuses with indicators
Gold plated input and output jacks
All steel 14 ga. Chassis, powder coat finish Peak clipping indicator LED, thermal LED
The entire amplifier circuitry (except the power output stages) is contained on one main drive card which also contains the input jacks. This means that the amplifier is completely upgradeable with future circuit improvements.

* Signal to noise ratio unbalanced input shorted input 80Khz filter -140DB
swept in a 4 Hz bandwidth below full power
* Signal to noise ratio unbalanced input shorted input 80Khz filter -160DB
swept in a 4 Hz bandwidth below full power
some residual flux (harmonics) present --- see graphs page
* Rated output power 8 ohms (conservative)
200 watts at less than .O2% distortion at any frequencybetween 20Hz and 20KHz
* Rated output power 4 ohms (conservative)
400 watts at less than .O5% distortion at any frequencybetween 20Hz and 20KHz
* Output impedance --- see graphs page
* Frequency response --- see graphs page
* Weight 52 pounds per monobloc
* Retail price $2500.00 per monobloc

12 output devices, 2.5 kilowatt power supply, gold plated input and output connectors, welded 9not crimped) ac cord, no fan, input selector switch, peak detector LED, circuit breaker power switch, turn on delay surge relay, twin power supplies with 100,000uf of power supply filters.

Complete stability into any load known by man with no oscillations or protection interference.

SO, James; have you done anything with your pile of Lightstar parts yet?

(if you have, you better drop that shit & ship my amp, damnit!)
