Good point! This is exactly what it's all about. Just look at users of tube equipment. Are they happy with their setups? In most cases no, they just keep rollin'.

Just an FYI for everyone not named Andrea reading this thread. Andrea registers several user names a day (a clear TOS violation), often carries on conversations with himself between accounts (just weird, I mean how lonely are you?), and posts the same thing over and over again (boring, old, tired, we get it). He's been permanently banned from this site and regardless of how many times he tries we're going to keep doing the same thing. As such, you'll probably see posts disappear from this thread from time to time which are, on the surface nothing "delete" worthy. But that's what is going to continue to happen. Every account will be banned, every post removed, no exceptions. If it upsets you how it makes the thread disjointed you can blame Andrea. We tried letting him back in and told him to behave himself, he didn't last.

Do whatever you ned to do to keep the membership composed of high quality, positive contributors.

Numbers and colors. Maybe not only synesthesia. Is there a touch of schizotypal personality trait?

Many of the opamps sound very good, just different.

How would this affect signature

OPA2111PK. in L/R
Transistor Buffers
2 Single AD 797s in G/V?

On a P3+. Am i right when saying i will get extended treble and stronger bass?

 

[leeperry]

OPA2111PK had dead mids for me...nice bass, though.

 

[12Bass]

OPA827 has a sweet midrange, IMO.

 

[ROBSCIX]

I like the OPA827's also. The AD797's are also great sounding opamps.

That set up on a P3+ is sweeeeet. I had that set up for ages.

It depends on the criteria you set, especially when you find such an aspect that is fulfilled by only one device. I feel the OPA228P opens the door no other op-amps have opened so far, so this made me staying calm since foreyesterday. However, keeping other op-amps in the chain problably keeps this corridor closed anyway. Try a headphone amp with no op-amps to be sure you left the clear path to be able to hear what is there to be heard from the DAC.
There is also a possibility that you don't want this because it could cut off the most part of the fun which is rolling. The HD800 told me the OPA228P is the right one, the PS1000 said the same, the GS1000 where more hesititating but cooperate very well with the OPA228P in the DAC so I remain satisfied with these assumptions.

 

[leeperry]

hah, you guys change your minds every week(day?)....ok I'll order some OPA228P free samples <clicky, clicky>

LT says my samples are "shipped", but 3 weeks later still nothing on my end

the bass is flabby on the 4562NA, this I won't change my mind!

my friend has given me my 49720HA back, so whenever I'll get my soundcard back from RMA....I'll try them again! I loved them on the STX

 

[majkel]

I haven't changed my mind in terms of getting rid of internal compensation. I liked the AD797 decompensated for a while but after another test it turned out unoptimal. So I went back to the OPA228P. I cannot use the AD8021 in my curcuit due to high supply voltage.

 

[leeperry]

ah well, I can only use dual DIP8 or single SOIC8(on adapters).....and the only SOIC8 they give as sample is the lowest grade(OPA228UA against OPA228U)

 

[majkel]

You can try the UA, there is just a bit more of "musical" coloration and a tad darker sound. The decompensation gain should be audible to you believing your head amp is "clean".
