The 511 seems a very good choice for someone already having a lunchbox. I don't think Focusrite offers the ISA in that format, but if you could find a used Red per.. this could be interesting too !I have to say this video and conversation has me leaning a bit more towards the RND 511 pre vs the ISA for my next pre
Very different beasts, the texture and silk option of the 511 seems to be appealling. I know you often aim for some mojo sounding gear.
I remember you telling me about the LA-610 and how you would push everything to maximum to see how it sounds.. eh eh eh !
I'm changing the tubes on one of them in a few weeks, I'll probably do a video on it too.. Stay tuned for that !
But this experience with the attenuator re-confirmed to me that the ISA is all about Clean sound, no noise, no distortion.. but still offers this nice transformer sound.
