Features of this Product

Go-Dap TT has cer tainly inherited the great features of the
successive products and is a flagship model in the Go-Dap
series. Go-Dap TT integrated the contemporary semiconductor
technology in the rich and soft tube sound and has succeeded
to eliminate thoroughly the microphonics noize, the tube's
weakest point.

Go-Dap TT is the best-suited tube headphone ampli er to play
digital audio sources in the highest quality sound.

To enjoy Go-Dap TT for many year to come, the easily-replaceable
socket-typed "Raytheon 6111 Sub MT Tube" is mounted.

●

The large capacity battery (3500mAh) makes possible the

longer playback time.

●

Digital audio signal is converted to S/PDIF by the (DIT built-

in)D/A converter and output from the 3.5mm round optical
digital terminal to connect with

other audio devices.
