Anyhow, returning on the ground... here we have a brand new, modestly priced at $.95, JFET audio opamp from TI to try. 🙂 Is anyone willing to go ahead and let us know? I'm a bit busy with other, more serious things in this period...so my samples (due to arrive after January 23 anyway) will probably have to wait for better times.

Fortunately, I don't work like a mule either, that's the reward for owning a successfull company.
I buy "better" because I can, quite simple really.
You are obviously thinking that everyone out here is in the same boat as you are, student, single (correct?), self opinionated, always right even when you are wrong and most importantly, in a life full of budgets etc etc.
I'd like to let you know that there's a whole world of folk sat behind their computers/laptops that are in many ways completely different in views, lifestyle, ambitions and monitary positions to yourself.
Not everyone spends most days/night forcing their opinions of opamps on forums, not too many folk even care about opamps (maybe a small number in comparison), or care how many words you can string together, how intelligent you may think you are or any of your over opinionated forcefull views in any form whatsoever.
You say you have passion in whatever you do, how about having a little passion for the oposite sex? that may cure your opamp fetish?
By the way (or BTW as you put it), I see why on almost every post you 'edit', maybe your little fingers type before your expansive brain has worked out what you actually meant to say?
In other words, get a life!
I care about opamps and most people do, too. They're a great way to tweak the budget gear especially. I understand this is not your concern. 😉
That said... I thought you noticed that I've settled with the OPA1611 as my favorite opamp to pair with the CS4398 chip. There isn't even a socket anymore, in my DAC. So that's all for me, for now. See you 🙂

That's all from me too, see you🙂
Ps. No more nasty posts from me, I understand everyone is entitled to their opinion, whether I'm in agreement or not. Chow!
Agreeing or disagreeing to anything is just the result of agreement (coincidence) or disagreement (contrast) of individual necessity. 🙂That's all from me too, see you🙂

See ya!
Sorry if it's been asked in this thread already... What's the best opamp to pair with AKM AK4393 DAC chip? And if I may also ask, what's the best opamp to pair with AKM AK5383 ADC chip? I'm considering to replace the opamps in my Delta 1010, which uses these DAC and ADC chips.
Thanks! 🙂
Hmm... I don't really know what would be the best performing in your circuit but... with the AK4393 DAC you would want to try these: LT1028ACN8, OPA1611/1612, OPA1641/1642, LME49725, LT1358, LM4562HA, ADA4627-1. Same for the ADC chip. 🙂

Hi nad
I for one have enjoyed this thread and Andrea's posts.
This is a DIY forum, and from what I've read thus far you have not actually contributed to this thread in any positive way, only in a criticizing way. So, it probably would be better if you did not post in this thread anymore.
thanks

Andrea, what little opamp would you suggest to put with this amplifier as a preamp?
STK465 SEMICONDUCTOR IC - eBay (item 250539668397 end time Jan-28-10 12:54:11 PST)

Heh, tough question 😛
Maybe I should give that chip a listen first, to see if its sound matches its numbers.. anyhow, the OPA132 could be fine with it?
I also enjoy OPA1611/12 a great deal, but do find myself using OPA211 more often for some reason. same chip, but I dunno thats just the way it happens 😉. I have found myself enjoying AD797 (properly bandwidth limited) and it is really superb IMO I sometimes use OPA1611/12 as buffer in the same circuit. other favorites at the moment are OPA827, OPA2107. and LME94710 whats with all these chips from different MFR with the number 7 sounding so amazing??
andrea: how would you compare the OPA1641/42 to OPA1611/12?

I deleted a personally abusive post. Any further infractions will result in SinBin time.nice to see my posts are deleted when other ppl attack the OP personally and their posts are still there.
before my post was deleted...I was simply saying that AD797B is amazing as AK4396 LPF...and LT1028A compliments it really well as final buffer, and doesn't ruin the fantastic AD797B SS

My "Grade RA1" (not to be confused with Grado) finally made it here from Hong-Kong. Built a box powering it from two 9V batteries. Close enough to get started. I am hoping fresh batteries don't cause too much offset. "real" power supply to be built shortly. Now I can start to see how much difference I can hear and how sensitive they are chip to chip for compensation and offset. Andrea has provided us with so much a tease, I just have to give some a listen.
yeah! 😀
I will solder some OPA1611 later today or tomorrow, to see what the fuss is all about
Typically the STK459, 461, 463, 465 sound like "very decent descrete" amplifiers, and certainly a heck of a lot better than almost any retail audio. Authentic chips have slimmer print, a code in the upper right and usually a "B" in the lower right.
I'd have to guess that "its sound matches its numbers" as it does have a reputation as being the reference for high quality midfi, circa 1978, and it doesn't take much hacking to get hifi out of it. For example typical heatsinks are quite small, so you can see that the chip is easy to get stable.
If OPA132 is something you'd actually use, then I could just buy it on faith, run it from regs, and hack it the rest of the way to a home run. 😀
Problem: Modern sources can't give the necessary shove to classic amplifiers. Solution: OPA132?
Hmm, sorry, they're not the same chip and they sound different, the OPA1611 being more musical, more coherent.. and I used the OPA211 quite a few times, without ever being too enthusiastic about it. The OPA1611 is a different beast, for my ears.
The OPA1641 looks less 'ultimate' in specifications... but I believe it will sound better than the OPA827 (being intended specifically for audio and claimed to have a "superior sound quality" just like the OPA1611) which is not a favorite for me..
