Matching Super rectifiier upgrade Royal-STR-1 and matching tube DAC Royal-DAC-1

Organic tube rectification line stage full balanced pre-amplifier

Using the cokebottle 6SN7 as the front end, and powerful 6550as the output buffer section, this unit is also built with a 6X5 tube rectifier with enhanced power supply. With the flexible capability of over 300 (over 1000 if add STR) different tube combinations, you can easily fine-tune the tonal quality of this pre-amp to adapt it to the rest of your system.

This pre-amplifier has a special HD (high definition) selector, it simply transform the internal circuit designs, and can give you a very high adaptability to different types of music. When HD is "ON" , it is good for dynamics Rock, Pop , Symphony and Jazz, while "OFF" is good for soft Blues, Vocal and Chamber music. It can also use to match different system characteristic and give out most natural musical performance. Even though this switch can change the dynamics and pace of the music reproduction, the change of the sound can't be detected by a regular measuring instrument. The specifications will not be altered, the changes are only detectable by the human ear.

This unit is fully loaded with our special enhanced features:

1. "micro-dynamics extraction" (MDE) circuit , which can achieve super quiet background with exceptional instrumental separations which we believes no others can offer, and let very weak music information effortlessly surface out right in front of you. So detail, high density with texture and vivid. You can hear the movement underneath the throat of the singer, and the fingers of those violinist or guitarist touching the strings as in real life performance.

2. Aluminum chassis with solid-wood side panels for most natural tonal quality

3. Enhanced constant current source design for best dynamics and detailings.

4. Enhanced input and output sockets, all gold plated ceramic tube sockets

5. All octal base big tubes design, which can easily surpass the sonic performance of any small or medium tubes (such as 6922, 12AX7, 6SL7..etc.) design with whatever price they asked for (even over $20K~$50K ) , once you hear the naturalness, musicality and dynamics of our big tubes design, you will never be able to listen to those old school dumb design again.

6. All 3D hand-wired with shortest wiring distance, without extra length of unnecessary cables, those heavily bundled wiring from many other manufacturers are just made for presentation instead of for the sound, which will only hurting the transparency, channel separation and musicality.

7. Variable output gain control, which can easily match with power amplifier with either very high gain or low gain, as well as any speakers.

8. HD circuit topology selector to match different system and music preferences.

9. Oil caps upgrade for super musicality and holographics sound stage reproduction.

10. Compact but elegant design with elegant royale color combo.

You can hardly get anything close to this design with even 3X~5X more expensive in the industry.
