I really do get my PCM2702E for $15.40 follow the link and see for yourself...
PCM2702E Texas Instruments Audio D/A Converter ICs
I really don't buy them by the 1000s as I can't possibly HAND SOLDER that many units...
I've NEVER used an OPA2604 and NEVER said it sounded great, although I'm sure it does,...
I did say the OPA2134 sounds amazing and this is true..
I'm sure you can find better sounding op-amps then the OPA2134 but NOT in DACs and AMPS costing $60 or less as I often sell my stuff for $49.99..... Really can you find a amp or dac with the AD797B/LT1028AC chips in them ????
If so where are they ??? ( I mean for $49.99... )
And the LT1028AC op-amp is a very nice op-amp on paper, BUT it really was never meant to drive loads lower then 600 Ohms... Driving headphones with ANY IC that is NOT spec'ed for driving headphones loads like 32 Ohms or 16 Ohms or even 300 Ohms just doesn't work all that great...
Most op-amps are only spec'ed out down to 600 Ohms, and below that, sure they work and work pretty good, BUT they DO NOT sound as good as CHIPs designed to drive the headphone impedances...
Yes, I'd like to make my stuff in better cases, but again for $49.99 it's pretty tough to do...
And I have YET to see any op-amps spec'ed out for driving 32 Ohm loads....
And also, I only use a couple audio grade amplifiers now, I don't use regular op-amps as I found they ALL lacked the esential audio qualities that I enjoy...
...
The above is just my personal opinion and Some facts thrown in to keep it real...

I only ran them on ±9V so YMMV...but: -Moon was distorted to death like those RMAA measurements are more or less showing: RightMark Audio Analyzer test: comparison -Sun V2 made me feel half-deaf, as there's a lot of tonal nuances it doesn't output(majkel said the same thing) -Earth was really nice! but the Burson V2 is the same, just muuuuuuuuuch better...clearer, more natural, simply far more enjoyable. so in the end I could have just bought one burson V2 and save time and money. to me the best opamps are AD797B/LT1028AC and the Burson V2...and majkel would agree on the two firsts: http://www.head-fi.org/forums/f6/aud...-v-2-a-397691/ RS does too: http://www.head-fi.org/forums/6402627-post77.html and what if the HOTAUDIO guy was calling an OPA2604/2134 "AMAZING"? customers deserve to know what they're buying...exact DAC model, opamps, etc. |
