Meaty, clean, neat and transparent sound with a sense of depth. A muscular and elastic bass. A mild mid range. And the treble is sparkly yet crunchy and nicely tapered off. Pairs beautifully with other Tiancoolkei gear, giving you the synergy of very authentic analogue sound. LDAC is supported. There is a volume knob. Great loudness. The RCA connectors make a tight fit. Equipment used: Poco F2 Pro, Tiancoolkei tube 01, Aiyima desktop tube headphone amp, Audio-technica Maestoso headphones, Xangsane ribbon RCA cables, DIY power cord, Audiowalle TP1000 power filter.

I love this little preamp. It is very easy to change the opamps in it. The tube has also been replaced by 12AY7, and various NOS tubes from 12AU7. But it was also grateful for the capacitor replacement. The stocks have been replaced with Elna Silmic II, Elna Cerafine and Panasonic capacitors. What can I say: you can tune this little preamp very well. Although when replacing a capacitor, space can already be a limiting factor. But it can be solved with some dexterity. And obviously the development is not over yet ... :)
