Luxman LV103 hybrid amplifier

An update for my HiFi system with this Luxman LV-103 hybrid amplifier with two 6CG7 triode tubes as preamplifier. The final amplification is done with mosfets.

I connected it to the pre-out of the Maranz sr7300, 5.1 channel AV receiver, as a separate amplifier for the two KEF R300 3-way stereo front speakers.


I use the Marantz with the excellent Crystel DACs for all digital input of TV with Chromecast (Ziggo, Filmnet, Spotify) and also the Raspberry Pi with HiFiBerry Digi+ module for playing my own music collection with Kodi. 

An 4TB hard disk contains MP3, FLAC, DTS and Video files that are connected to this mini computer which is connected with toslink (SPDIF Optical) to the Marantz 7.1 surround amp.

I connected the Phono-preamp (Tonar Vinyline) to another analog input.

Conclusion: Very smooth sound with good imaging and air.
Instrument separation, deep soundstage and insanely clean noise floor continuously blow my mind…
