The holidays allowed for some recent upgrading with 3 new HPs in the last couple of months, a complimentary amp upgrade only seemed fitting, so after a little research, i decided on the SA-1.
After switching out my THX789 which has been my main amp for 2 years, the first thing i noticed was how smooth and transparent with better imaging and depth that has been unveiled. They also share the similarly dark back-ground noise, at nearly THX levels.
Though i still love the analytics and power/performance of the THX 789, i must admit i'm enjoying the music more
with the SA-1s, whether critical listening or just chillin. I also found it necessary to flip the 4 gain switches under the amp to high gain when trying higher impedance cans.
Singxers better flow and ease with notes exude a more fluid and naturally/rhythmically tuned sound signature, which is warmer then the 789s. In comparison the 789s over all sound a tad dryer, but comes back with a slight advantage in punch and a touch brighter quality, narrowing the performance gap.
Dependent on ones preferences with music, headphones, DACs, as well as budget, and considering the close performance levels, the THX 789s remains the better value.
The analog presentation of the SA-1, probably because of the caps and transistors used, provides that more organic yet precise sound signature i think i was looking for with hybrid tube amps, as i found full on tubes a bit thick.
Being truly balanced and mostly Class A, the Singxers ability to emit more transparency and depth, justifies its price, and the enjoyment i'm currently experiencing
ndgns Drop THX not a better value because of the cheap internals that are used including the worst pots in the business including glued on volume knob that will become noisy in 6 months. Singxer uses high quality components that will last 5 times as long vs drop. Not many people talk about quality internals as being an important consideration.
Paullieb213Hi, our definitions of VALUE, seems to be your main point of contention here? I use it in a budget context and you in a more quality one, as i think i have touched on your other points. Sorry to hear you've had some bad luck with your THX 789's. Thanks for your reply, Cheers!
