Hello. Andrew Sparks from Sparkos Labs here. We have a new discrete op amp product that launched a few months ago. It features all class A biasing - including the output stage, Two Pole Compensation, very low noise, and DIP 8 compatible packaging. This device has a full data sheet and is available as a single or dual op amp. It can be used to upgrade virtually any audio op amp in your system, and is great for new or DIY designs. For more info, reviews, white papers, and a full datasheet, please visit http://sparkoslabs.com/discrete-op-amps/
Hi Andrew,Very interesting couple of devices you have here, and you have engineering specifications too! Just try finding any of those in the capacitor discussion threads herein. Anyway I do use high quality single linear op-amps in some of my solid state preamps and phono preamps, typically OPA627s.I would sure like to acquire six of your singles for a good trial evaluation in my lab. Where does the price break begin for orders more than one ($39)?Frank Van Alstineavahifi.com
Hi guys. Thanks for the warm welcomes. The SS3601 is what you need to replace a OPA627. Im doing 10% off all this month, but Ill give you guys from the forum here a better deal than that though! I see some of you have sent me emails to my site, Im going to answer them just as soon as I make this post here. If anyone else is interested in trying out some of these devices, just let me know!
I'd be very interested in trying these. I have Burson's (2 duals, and 2 singles) in my DAC. The biggest issue for me is that I can't properly fit my cover on with the Burson's. These would be great in that regard!What's the best way to contact you?
Andrew:What's the story on the low gain version? Did you just up the value of the emitter resistors or current source on the input stage? Is it better suited for certain applications?Tom
Is there any chance that it might become available with a 40v/us slew rate and symmetrical slewing behavior. Scotty
I ordered a half a dozen of the singles to try in both my Vision phono preamp and in the line stages of my solid state preamplifiers.
