Pure Class A single-ended tube + MOSFET + UTC OPT x 4 headphone amp with preamp-output

This is our newly designed headphone amplifier, use

2x 6SL7(default) / ECC35 / 5691 / 6SU7 / 6888 / 6SN7 / ECC32 / CV181/ 5692 and all compatibles +

2x 6L6G(default) / KT66 / KT77/ KT88 / KT99 / KT100 / KT120 / KT150 / 6550 / 6CA7 / 5881 / 6K6 / 6G6 / 6F6 / 6Y6 and all compatibles.

. The following is the special features of this design

- Super quiet "hum-free" design, highest signal to noise ratio with darkest background performance

- Micro-dyanmic-Extraction (MDE) circuit for lowest noise floor with enhanced micro-dynamic and macro dynamic performance.

- All component-to-component and point-to-point hand wired

- Pure class A single-ended from input to output without -ve feedback

- Dual tube stages and single stage MOSFET driving a quad of NOS UTC high grade output transformer, least possible parts with most transparent and micro dynamics sound

- Fully balanced input and output with single-ended input and output as well

- Direct single-ended RCA output + transformer coupled XLR + RCA output for power amp connecton

- ture balanced XLR headphone and 1/4" regular headphone connection capabilities.Capabile to drive headphone with impedance from 16ohm and up to infinity. Output power 1Wrms

- High quality high precision instrumental grade components

- Sweet and smooth tube sound with high power MOSFET and UTC output transformer, can drive most of headphones to reasonable loudness level

- Very smooth and sweet vocal or instrumental sound due to the ultimate high quality UTC output transformer

- H / L switch for 1/4" headphone output to match different impedance and sensitivty

For this same low price,it will be extremely difficiult to find another products which can sounds better than this amplifier.
