This is a first for me; I have never lowered the noise floor on my system before. I have increased transparency consistently but never lowered the noise floor. I’ve been listening critically since the early ‘80s and have used a wide variety of components in the last 45 years. I greatly prefer tube amplification and enjoy building my own, but I also buy commercial units every now and then.
After adding the Tai Hang to my system, I noticed some things right away. Dynamics, especially the low-level details, are noticeably better. Think about brush work on cymbals…those subtle accents in the background that are contributing nuance to the music. I’ve certainly experienced increases in transparency and low-level details during prior upgrades, but there was a subtle difference this time.
There’s just something different between increasing the resolving power of the system and reducing the noise level. I can’t hear “blackness”, at least my brain can’t, but I can certainly hear a number of small things now that were buried beneath the noise floor before I cleaned up the mains supply. The decay of notes are longer and clearer; they don’t get chopped off when they hit the noise floor, plus the low-level dynamics I mentioned above.
I started my evaluation with my headphone system, which is simple, but has good resolution. It’s not uber high end but it definitely has enough transparency to identify small changes in the system. FWIW, this is my 7th standalone DAC and it’s a stunner, especially when fed a clean hi-res signal. I put a very light load on the Tai Hang in my initial use case, so I can’t verify what it does with heavier loads like a power amp. Next month, after I upgrade my power amp…
