Amplifiers with two headphone outputs are not uncommon now. However, these ones, which we have already got acquainted with, have only one general volume control, which is not very fair, since one of the two listeners will probably have to be content with not the most comfortable volume. C.E.C. HD53R Ver8.0 has two separate controls. Moreover, each "half" has two connectors - 6.3 and 3.5 mm, what eliminates the need to use adapters. In addition, the right regulator controls the outputs for loudspeakers - they develop power up to 2 x 10 W at a load of 4 Ohms.
Another feature of C.E.C. HD53R Ver8.0 amplifier is the presence of balanced inputs (XLR), which are switched with usual ones (RCA), allowing you to connect the amplifier to balanced sources. Interfaces are switched by the button on the back panel. There is also a gain selection toggle ( 12, 0, or 6 dB).
Two proprietary patented technologies are implemented in the amplifier: LEF (optimizes the operation of the output stages) and IGM (intelligent volume control, which allows to avoid distortions when the gain changes).
And, judging by the sound, both technologies are very effective - the amplifier plays extremely large and expressive. Switching the gain to -12 dB makes the sound more sophisticated and noble; at 6 dB it gets a dramatic brightness. A position of 0 dB gives a neutral and extremely accurate transmission. Here are luxury bass, great dynamics, and, at the same time, no sharpness.
C.E.C. HD53R Ver8.0 amplifier easily withstands the pass to a low-impedance load - in AKG K271 headphones, a slight emphasis appears in high frequencies, the lower part of the range becomes a little more restrained. But this is clearly due to the nature of the headphones themselves.
In hard rock from Def Leppard, there is a feeling that the dynamic range is slightly compressed, but this does only a power of good - there is no impression that the music is pressing on the ears. All instruments are clearly audible, although I don't want to analyze this sound stream at all - the music just lugs away...
Der Solaris – DAC von AudioValve ist ein High-End Kopfhörerverstärker, der sämtlichen Kopfhörern zu einem neuen Level der Wiedergabe verhilft. Darüber hinaus ist er extrem anschlussfreudig. (Dr. Mertens – EAR-IN – Mai 2018)
Audio Valve Solaris-DAC – State-of-the-Art – more than just a headphone amp!
The latest 2018 version. 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 of 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-DAC 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.
The Solaris-DAC is more than just a headphone amp, it’s more like a Swiss Army Knife in the Audio World, a full-fledged desktop system. 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 and speakers too.
