I had considered purchasing a Golden Gate II balanced but passed as it was a previously owned unit in Germany with no possible way to demo. I decided to go with the latest Golden Atlantic TRP3 balanced and it is better than I could have expected. If you get a chance I would definitely recommend listening to one.
I’ve never owned a Terminator but I do own an Aqua La Scala Optologic MKII and had honestly considered the former a step backwards. The Aqua responds well to tube rolling as well, especially (at least as I’ve found) with older NOS Telefunken 12AT7’s. I’ve heard from others that NOS Tele 801S and Mullard 6060’s are also very special. IMO the Aqua is a fantastic dac and I’ve chosen to keep mine even though I use the Lampizator for daily use.
The Aqua has a beautiful sound- especially in the midrange though some claim it to be a little rolled off in the upper frequencies. To “me” this trait (compared to other dacs) meant a more natural presentation that made others sound harsh and led to more fatigue.
While great the Aqua falls behind the GA TRP3 when it comes to overall drive, soundstage and detail. The Lampizator was definitely a large step forwards. If considering a GG 2 or Big 7 bear in mind that you may be looking at considerable cost should you decide to pursue upgrading to the latest circuit/processor but that also could be a good entry point for you if you’re considering a DHT dac.
Good Luck!
