Well, you're #1 -- and #2 -- in my book.
(and you'll be hearing from Julia Roberts' lawyer)
How can you describe default mode vs dc mode?
Opamp 1612A
Yes, unfortunately, it does not work as good as it should. This amp has a very deep recession, like 5mm almost. This knob could not grab the axle, almost. Had to sand the knob rear, and the fixing screw to make it flatter where it touches the pot. But If I get the proper machine I can sand it 1-2mm more, then it will be ok. Otherwise it turns a little bit crooked. Apart from that, not only looks very good but the molted surface goes to the very edge, so it is always there. Also available in silver this knob.That looks really good mate

Do any of these mods increase max volume output? I am still concerned that my other amp which is rated under 5W gets way louder at max volume.
I find myself maxing out (and wishing for more) the SA-1 on certain low gain tunes like Pink Floyd stuff, which should not be happening…

I'm back one more time... LOL!!!!!
I only burned in the SA-1 overnight for a week, and used it normally the rest of the time. Today, I was greeted with a fully burned-in SA-1. Just wow. Take the clean, detailed sound of a THX amp like the 789, replace the soulless midrange with one that is full, detailed, dynamic, and a bit less bright. Now take the 2-dimensionality of THX amps and replace it with actual soundstage depth that sounds nice and "holographic". The result is the SA-1. Could not be any happier with it. I may try the jumper mod in the future, but for now I'm leaving it as is. Now back to your regularly scheduled thread...

Funny because today was “the day” for me...the day it hit me that I can no longer bare the sound of my thx 887, an amp I once loved...a burned in sa-1 is really solid leap forward. Especially considering that I almost returned the sa-1 because I could barely hear any difference between the two in the beginning. Now when I A/B them, the 887 just disappoints me. I will be selling the 887 soon. Only reason I still have it is because I’m using it to monitor the sa-1’s progress lol Thanks singxer!!I'm back one more time... LOL!!!!!

I compare in one song and I swap manu times quickly. I felt more tight. I will compare more later but have no time.
One interesting finding, I compare DAC smsl m500 using RCA to SDA-6 by XLR. The SDA-6 has surprise more bass and punch which I was not expected to hear.

Thank you ever so much. @Muataz

It may be an option as people prefer Sparkos to the Bursons. I am no EE but have done soldering and electronic assembly for 20 years. The foot print can get in the adaptor but not sure if there is space for the customs width wise to replace the Burr Browns....
i have only Capacitor rolled in my Headamp Gilmore Lite Mk2... If Sparko says the Op amps are ok to swap.... and foot print ok i may try it.... but £70 per Op amp UK... Value propositions always a killer...
A cable, a fuse, a power supply, anti vibration... weights.... Then you tell people its a bargin AMP.. and spent as much or more pimping it out....lol
Options are available and something to think about at least for fun...

Well I am also really loving my SA-1. So much so that I held off buying the V280FE and pulled the trigger (at a steal) on a set of 2021 LCD-XC from a dealer in Ontario. I know they don’t take much to power but they should sound pretty good on the SA-1 I am hoping. Anyone else have them on this amp already?
