Audio Valve Solaris Headphone Amplifier
Audio Valve Solaris - State-of-the-Art - more than just a headphone amp!
Based on the concept of Audio Valve's Luminare, the form and equipment of Solaris has been adapted to RKV 3. In addition to extended features like balance-control, more inputs and a remote control which has been integrated for volume, the front plate od Solaris now has the same connection options as Luminare while offering twice the performance on all outputs which on average is 8-12 watt per channel, depending on the headphones' impedance.
Solaris is the logical synthesis of Luminare and RKV 3 and reflects perfectly what the Audio Valve team defines as STATE-OF-THE-ART product in the premium class of headphone applications when talking to a number of customers worldwide.
Solaris can be updated and equipped with DAC and is then called "Solaris-DAC"
The Solaris-DAC is more than just a headphone amp, it's more like a Swiss Army Knife in the Audio World (German: Eierlegende Wollmilchsau). It provides inputs for all sorts of headphones including Stax, analog inputs, USB input for music server and computer, MM phono input, pre-amp out for power amps, direct speaker output for high sensitive loudspeaker...
...and THE ONE AND ONLY headphone amplifier on the market that is able to drive all standard headphone loads, starting from 3 Ohm up to 145 kOhm.

Martin Mertens about the Solaris w/DAC in the Ear-In magazine (May 2018):
"...the Solaris DAC from AudioValve is a high-end headphone amp that boosts all headphones to a new level of sound reproduction. In addition, the Solaris is very generous with its connections, offering every type of standard connector. Best we've heard..." CLICK HERE to read the entire review (in German)
Lieven of Headfonia.com wrote (Feb.2018):
"...another thing I really love about the Solaris are the dynamics and speed with which it delivers your music, the Solaris has great PRaT. On top of all this from bass to treble you get a very high resolution, the level of detail just is impressive. A high level of detail doesn’t mean this amplifier is analytical, cause it is not. Think musicality over pure analytics but always with great clarity. If female vocals are your thing (they are for me), then you will love this amp, but in general the Solaris voices are exceptionally good, natural and romantic... the Solaris does everything so effortless, it is a pure pleasure to listen to. It’s musical, rich, extended, easy on the ear and completely non-fatiguing. What’s not to like?"

Mike Portnoy, TheHeadphoneList.com concluded:
"...AudioValve Solaris is an all-in-one vacuum tube amplifier that provides an amazing three-dimensional soundstage and an impressive treble presentation. With its unique main board and the output power, it is able to drive HD800s, HD800, and HE1000 flawlessly. When it comes to its etiquette, the Solaris is not an affordable audio gear. In terms of the sound quality, some other headphone amps can be considered as options for 4.700 Euro, but considering its connection richness and the overall sound quality combination, the Solaris would have an acceptable and favorable price..."
