a big difference between DVD players and CD/SACD only players is that the latter operate just on single clock frequency, while the former needs to run three of them - 27MHz videoclock together with 44.1k/48k audioclocks.. usually the player's main chip runs on 27MHz crystal oscillator but also...

I've just discovered this great trumpetist, his music is a skillful combination of jazz with many other genres like funk, dnb and such.. really worth listening to! I've only heard two of his many albums - The Dawn (1998) and Bending New Corners (1999), both are great and I have no doubts the...

really interesting reading, you won't regret the time spent reading it I promise http://milbert.com/tstxt.htm also look here, various devices tested in similar configuration with distortion spectra plotted.. especially notice the absence of >3rd harmonic in case of simple triode and the...

I've just received my 1212m and took of that sticker on the main chip, the markings are milled, but there is a clear trace of the bigger letters and it says Creative Audigy, not even Audigy2! now it's completely clear, it's just an old 10k2..

hi, I'm looking for some dirt cheap DVD-Audio player.. what I need is true 24/192kHz stereo output without messing-up the signal with any 'enhancements' and 'features'.. this one looks good, I even saw it's manual and it seems all of the ballast can be switched off in menu.. I'd like to know if...

right now I'm working on Blue Hawaii, starting with the amp board schematics.. here you can find schematics posted by Dr. G himself, hope it's correct.. and here is my redraw in Eagle.. btw. why is justin using two more A1968 in the current sources than what's in the schematics

yesterday, I went to the local Stax distributor to finaly hear my Stax SR-Lambdas bought a month ago at ebay.de.. the first positive thing was - they worked! I went straight to the most expensive amp SRM-007t as I wanted to hear what they are capable of.. as a reference I used new SR-404...

I've just finished laying out pcb for two pole active Bessel filter at 75kHz.. it's intended use is on friend's Audigy2 ZS card, which even after opamp replacement and power supply caps upgrades sounds still horrible this is my last attempt to make soundcard out of that crap.. it connects...

hi, I've been thinking about using some current output DAC with dynahi, this design is simple, current from the DAC's outputs (balanced) is injected to the emmiters of the input transistors T5, T6, this point is kept on ground potencial using T3, T4.. T1, T2, LED1, LED2 and R1, R6 are current...

Hi folks, I'd like to see what's under the hood of your DVD-A players, cheap ones are especially welcome! try to look for DAC chip if you can, take a photo and post it here.. many thanks!

I've been auditioning two compilations from local audiophile magazines, one with pieces from Telarc and the other from Chesky and to be honest, Chesky was far better to my ears.. so I'm curious about your expirience with these labels..? btw. both were jazz compilations..

Specifications Type:Electrostatic Frequecy Response: 8-35 KHz Sensitivity: 102dB/100v rms Maximum Output: 109dB Bias: 230V ("normal") which model is it? I'm about to buy them, but I want to know something about them.. thanks!

Second generation PPA Diamond Buffers are here! for information about them start browsing the thread from the last pages relevant information regarding 2nd generation buffers starts at this point.. For the newcommers: last year I have developped Discrete PPA Diamond Buffers as a...

read the stellar review from well-respected audiophile website here: http://www.firebox.com/?dir=firebox&...roduct&pid=691 Quote: These ultra bombastic babies really come into their own when the subwoofers are cranked up - all round clarity is truly staggering: explosions sound...

I'm thinking about designing some very nice DAC, I'll be using PCM1798, which has current outs and I'd like to know what are possible ways to do I/V conversion.. passive - resistor to ground active - opamp w/ feedback resistor ??? you can list advantages and disadvantages of each...

do someone know where to get those encapsuled isulation transformers for s/pdif cheaper than for $8+ at Digikey? I can have two sets of optical transceivers/receivers for that price or maybe some type not specificaly for digital audio would also do?

enjoy this is for my friend's Kenwood DP-7090 equiped with total of 8pcs of BB PCM1702 DACs and now with 12pcs of OPA627 on dual DIP8 to SIP8 reductions.. we'd like to find out how does Gilmore compare to various opamps, so that's the reason for this board you have to stack two of these...

please comment & suggest improvements.. size of the PCB is 60x60mm, mostly SMD parts used.. schematics here.. edit: some minor changes, now 55x60mm

I have two LT1963As lying around that I want to use for the aditional power supply for my soundcard.. generating +/- 11V out of dirty +/- 12VDC from PCI the question is how can I configure it as a negative regulator? in the datasheet there is stated +/- 20V input and output, but the...

the question is clear.. I've saw somewhere sometimes that it doesn't help a lot or even not at all.. I'm asking becouse I've just biased AD826s with 3mA each channel - I use them as a buffers after AD8620 as I/V and filter stage on my Revo soundcard and it does help them MUCH! what are your...

Today, me and my friend and also head-fier Karlosak, we went to Czech official Sennheiser distributor and had the opportunity to audition the new HD650 against HD600.. the source was some higher end Marantz CD player and amps were Creek OBH-11 and my own DIY Gilmore Dynamic.. Creek wasn't bad in...

I'm designing PCB for balanced version of Gilmore including Elliot's capacitance multiplier PSU on the standard dual-sided Eurocard board (160x100mm).. just to let you know here are the holes placed as they'll be on the real board and comparison with unbalanced pcb from mcnowinski based on...

I'm going to make another Gilmore, this time the fully balanced version, but I'd like to use different transistors in place of the four parallel 2SA1015 and 2SC1815 on the output.. I want to substitue them with just one piece. I found 2N2222 and 2N2907 which are 600mA in contrast to 2SA1015 and...

apparently 25R, 1K, 10K and maybe change also 5K
