OP AMP Capabilities in Supporting 24 bit bandwidth

I don't know anything about this particular OP amp, but..

1...Every OP amp circuit I ever saw had about 60 transistors.
2... Every OP amp circuit I ever saw had a complementary circuit topography. (That's part of the reason for so many transistors).
3... "16 Bit resolution" is a roundabout way of saying it has a dynamic range of 96 dB.

It may be a good preamp and a good OP amp, but I get a bad feeling when specmanship is evident.

Hi
You seem to have locked on a bit of information presented for those digital engineers that have a problem in the analogue realm. Looking at the full spec sheet for the 797 you will find Slew Rate and two listings. 1 for "12.5 volts per microsecond" and one for "Settling Time to 0.0015%--10 volt step --800 nanoseconds" The 0.0015% is the precent value of the LSB for a 16 bit DAC, hence the 16 bit settling time. Analogue folks would have simply divided 1 microsecond by 12.5 volts and multiplied that by 10 and found that 800 nanoseconds was the time that the 797 required to respond to a 10 volt step. Now the difference between a 16 bit audio system and a 24 bit system is dynamic range NOT frequency responce, that depends upon the sampling rate. The full power bandwidth of the 797 at a gain of 10 is 8 MHz, much more than sufficient for any audio system. Back to dynamic range. A standard CD as a maximium dynamic range of 96 db, 6 db per bit, a 24 bit system then should have a dynamic range of 144 db but due to noise limites of the recording and playback loops you will find that the best units specify a range of 110 to 115 db. The 120db noise limit of the 797 exceeds those values by a fair margine and will add no audible noise to any system on the market.

I completely agree with cornelius. 24 bits is a dynamic range issue, not bandwith. The 797 was designed before 24 bit digital audio existed as a regular format, which explains the published information from Analog Devices (and the ELAD spec's). I suspect you may be asking about sampling rate - 96kHz or 192kHz which are also non issues with the 797. It's bandwith exceeds the requirements of 192kHz sample rate by many times.
On a more subjective note, I've had a chance to use an ELAD and it is completely transparent. If you want minimalist, it's a good pick.

I checked out this preamp, and find that it has only 6dB gain, with a switch option for unity gain. It is easy to get distortionless ("transparent") performance from a low or unity gain amp. The trick is to do it with about 30 dB or more gain. I guess you could call this item a "straight wire without gain".

Thank you all, your responses are giving me the most confidence in the ELAD unit. Iam going ahead with the purchase.
