![]() ![]() 192Khz files will pass through the DAC and use 96Khz processing. The DAC 5.1 signature was developed from the ground up to focus on every aspect of digital reproduction that will ultimately have an impact on sound quality.Īll the Audio Note DACs use the AD1865 chip and support RedBook 16/44Khz plus 24/96Khz files. Philosophyĭeveloping an ultra high level DAC requires special attention to not only the digital circuits, but even more significantly, all the analog aspects of the design as well. Both of these aspects ensure excellent system matching. They also have very low output impedance and can run long interconnects. The C-Cores bring a level of detail and authority across the entire spectrum and increase definition, authority and high frequency detail, bringing an incredible accuracy and realism to the music. The triple C-Core transformers at the output of the 5.1 signature ensure the highest quality transfer of the analog signal to your pre-amplifer or intergated amplifier. We firnly believe that your high end vinyl system will have trouble keeping up. The results are staggering dynamics that most audiophiles will have never experienced. The SHUNT design in this unregulated power supply enables the ultimate dynamics and detail, instantaneous current supplies are available to the ever changing analog signal running through the system. Thus each tube on the output stage has its own dedicated HT path. The overall design of the power supply incorporates three substantial chokes supplying two separate HT voltages, one for the 12AU7 input stage, and one for the ECC99 output stage. This 5U4G variant is a powerful valve more commonly found in 300B amplifiers and there is plenty of NOS choices for this position. In the DAC 5.1 signature we start by having two separate mains transformers one dedicated strictly to the HT voltages that power the line stage, the other supplies our new super regulation board and the line stage DC filaments.Īt the heart of the power supply is the new WE274B (replica) rectifier tube. ![]() I haven't heard one yet, and read it is very good on up sampled PCM to DSD.Demanding audiophiles know that power supply design is absolutely critical for the ultimate in sonic performance. I had an option to buy a GG recently but it was the earlier unit without the discrete PCM board which upgraded the Redbook. Yes, I do find the Lampizator Golden Gate interesting. I am still in the process of replacing the tubes and swopping out the copper caps, so will get an idea of how much better in a few weeks, and report back. I had a maxed out DAC 4.1 Kit as well and it was great. It might be worth your while giving the latest Lampi product a spin. ![]() The Lampi Big 7 I used before this was also clearly superior to the AN in my system (and it teased me into reaching for the GG). The Lampi gear has all of the strengths of the AN, just more so. In my principal system I use a Lampizator Golden Gate, and it is just so much better than the AN piece - "shake your head real" many times. I still use this DAC in my second system. It is a great DAC for the money IME, and it easily displaced my EAR Acute with greater body and "feel" of all instruments, more completely realized timbre, and a greater 3D soundstage. I built the Audio Note Kit 4.1 LE and subbed in some VH Audio CuTf caps on the output, plus rolled all of the tubes a fair bit. ![]()
