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
