Nutube hybrid headphone amplifier with Harmonics stabilizer. 100% handcraft in Thailand.
Fully researched and developed circuit for NUTUBE to get better sound. Excellence music reproduction with Harmonics stabilizer circuit. It is a different from other NUTUBE kit (other NUTUBE was phase inverted), because, we do research about NUTUBE phase response behavior. Then, we put our topology into circuit to ensure a correctible sound reproduce. This NT-HP has 4 key sections;
-Harmonics Stabilizer
-JFETs Buffer
-NUTUBE SE
-Opamp Buffer
First section used matched pairs JFETs. For 2nd section, we use
matched quad JFETs for the best performance.
TKD potentiometre is used for volume control after Harmonics Stabilizer circuit (not attenuate inputs signal anymore)
0.5%-1% audio grade resistors are used on this PCB and tri-cap coupling for output signal.
Muting relay time 7 seconds for NUTUBE warming.
No need any internal battery to get low noise. Therefore, you can use any 5V POWER BANK on the market to supply it.
Tuned by ears every units by the famous, which is known from ZEN of Headphone Amp in THAILAND.
1 year of researching and comparing with many headphone amp during design term.
The product was exhibited in Thailand show. And, there are many users interested in this product.
Warm sound, more dynamic contrast, realistic experience, hologram; all of what listener need are contained in NT-HP !

ибася как всегда, когда у балансного dc 01 норм выхлоп, так и написано 113mW на 32Ом, а у этого, напоминает как у dx120 ... указали баланс, а SE 1.8 Vrms ... ещё дописали общий показатель по палате 400 mW )))))
