Well, in general, all opamps pretty much sound different at different voltage levels. So it's not psychological at all. Usually the higher the voltages, the better the sound. Maybe what you're hearing is the bad source.

Hi guys, My sister is getting someone to buy an ipod from the US. Is it possible to get it serviced in canada if something breaks? Thanks

CS8412/CS8414 into TDA1543 dac running at 8-9v with simple I/V resistor.

great, thanks for your responses guys I believe my questions have been answered

JCX.. i'm actually using my sds amp as a preamp for a speaker power amp. So am i right in assuming that a higher voltage is better in terms of distortion? (This is from your second paragraph) And I think you should rephrase your third paragraph because I am completely lost understanding it. Can...

I found this information at the link below: http://www.phys.ualberta.ca/~gingric...s/node115.html "The op-amp performance can be demonstrated by applying a step function to the input and observing the output response, as shown in figure 6.33b. The actual output will have a finite slope...

Hi guys, I can definitely hear the difference when i change the supply voltage on opamps in general. At the moment, the opamp i'm using is the LT1122 in a modified SDS headphone amp. How come the sound changes so much? I was reading the AD8610/AD8620 datasheet and noticed that two things...

"What are you on? The Audigy 2 is the best sounding consumer PC soundcard." Umm... i should ask you the same question...

Yes, I do agree that the OPA134 series has more noise than a 8620, but i'm not sure if this will be audible because the hd650s are 300 ohm headphones..

I just want to add that changing the ground channel opamp also makes a difference in sound.. what i'd suggest you do is stick another ad843 in the ground channel and this will definitely calm down the highs.

Ok people... my friend is on an extreme budget and can only spend about 75 us dollars. He likes the look of the ATH-FC5 white headphones. His other choice are the sennheiser hd-497s. I've recommended the senns over the audio-technicas, but any further advice is welcome. Please post comments as...

i think Iron_Dreamer is gonna go insane now..

Yeah I have an Emu 1212m which has asio support. Weird thing is, i can only get the asio to work in foobar if i set the mode to 24 bit padded to 32 bit.. does anyone know why this is? The error i get is the following if i set foobar's mode to 16 bit or 24 bit: "unsupported output data format".

Hi thanks for the quick reply, Is there a reason why ASIO is better than kernel streaming? Just curious, 300_baud

Hi there, Got a few quick questions regarding foobar.. my first question is about the kernel streaming.. does it only work in 24 bit or 24 bit padded to 32 bit? or can it also work in 16 bit mode as well. Second question is about ASIO output. Is ASIO output just as good as kernel streaming in...

Kernel Streaming only works with windows 2000 and newer if i recall correctly.

The low pass filter cuts off the higher frequencies that contain distortion that the dac creates when recreating the analog signal from digital. This distortion can be harmful to headphones and speakers. (Especially to speakers that have tweeters.. the distortion may wreck them)

Hi, Quick question.. is there a place in canada that sells the chaintech av-710? Thanks, 300_baud

Matt_Carter: I can tell the differences between two different toslink cables and a coax cable. You should try it yourself! Later, 300_baud

Hi Solude, Thanks for the quick response! But i have another question. What is the difference between electrical and data jitter as i have never encountered this before? Thanks again, 300_baud

Ian, how can toslink not be connected to the computer's power supply ground when the optical transmitter must be hooked up to ground in order for it to work? Thanks, 300_baud

Hi, i have a 550 unit myself and it sucks actually.. the reasons are: 1) It skips a lot... especially when the battery life is at half left. 2) The skipping, which includes 'tick noises', means high jitter. 3) Turning off the xtreme EQ/3D settings doesn't really help... 4) It does work...

Hey Morsel, that sounds like a great project, can't wait! edit: Just thinking about your proposed project and the mosfet ground channel. Wouldn't the PSRR of the ground channel as a whole be worse with mosfets? If so, then wouldn't it better to stick with buffers instead? Also, what...

Yep built many SDS amps. Currently, my sds amp is using 2sk214 and 2sj77 hitachi mosfets, Riken Resistors, OPA637 opamps, Silver Mica 47 pf caps, Panasonic FC and HA electrolytics, Class A biasing PPA style with 2n5486 and 2n5484. (Read this thread in which i asked craig buckingham on how to do...
