Musetec (LKS) MH-DA005 DAC

as I have already stated, the MUSETEC has been inserted in a pure class A Gryphon system (https://gryphon-audio.dk) at my trusted dealer (https://www.evoluzionehifi.it/).

it was compared for about two months with all the DACs present as a demo in the store (as mentioned, from the NAGRA HD DAC X, to the dCS Vivaldi APEX DAC) plus some Topping DACs bought for fun (DX7Pro and DX7Pro +).

I have already expressed the results of the comparison

has any of you had the opportunity to test MUSETEC on a better system?

do you know any system, better than the one we use, which operates in pure class A and which is such as to allow you to appreciate the (sometimes significant) differences between the different sources?

I am willing to welcome feedback from anyone who can test the MH-DA005 in a better system than the one we are using

just for fun ..

Pure Class A

True Class A operation has always been a Gryphon hallmark. Why? Because no other circuit topology can match the sonic perfection of pure Class A. Unfortunately, true Class A is even rarer today than when we introduced the legendary DM100 in 1991. Rising consumer awareness has forced some manufacturers to make outrageous, unsubstantiated claims of Class A power ratings that have more to do with marketing than technology. There are a growing number of so-called “new” Class A topologies based on automatic biasing which supposedly allow the amplifier to sense when the bias should increase to ensure constant Class A performance!

Put bluntly, you can’t cheat physics. There are no engineering shortcuts when it comes to pure Class A, so we repeat with no apologies: TRUE, PURE CLASS A means heavy transformers, very large heatsinks, large quantities of expensive parts and costly assembly. While we appreciate and endorse every effort to conserve energy and preserve our global resources, our research into efforts to obtain Class A performance from class A/B topologies makes it clear that there simply is no substitute for the sheer magic of pure Class A.

However, based on thorough analysis of typical listening situations, we have invented “Green Bias” (“Green” for reduced environmental impact). Green Bias offers TRUE, PURE CLASS A with considerably lower power consumption than traditional solutions.
Green bias in the new Gryphon Apex allows the user to select the amount of Class A required to run his speakers fully in Class A at any given time, encompassing such factors as speaker sensitivity, room size, musical dynamics and overall volume level. Green bias improves on our programmable bias by giving Gryphon’s fortunate system owners the option of letting the preamplifier automatically control bias.

While Green bias does not match the extreme low power consumption of Class A/B, or even the low power consumption of misleading “auto-biasing” systems, it does offer significantly lower power consumption without sacrifice or compromise. PURE CLASS A performance is guaranteed! Apex users who own legacy Gryphon preamplifiers lacking Green Bias can access the programmable bias system manually via the Apex front panel.

The whole point of voicing is inherently subjective, either manufacturer and you sympathetic or not. Bobby wasn't trying to voice Merlins to appeal to every listener, no universal voicing for the masses. Above also may apply to specific genre of music a component or system works best with. VSM is particularly sensitive to this issue as lower bass simply missing in action.

Again, voicing is based on long term listening with variety of music in static system.

So, I owned Auralic Vega, LKS004, Okto Dac8 stereo, Musetec 005, all in house, comparative listening sessions. Based on ASR reviews, Okto one of top measuring dacs, Musetec pretty lame. And yet I heard greater resolving capabilities with 005 vs Okto, based on their measurements shouldn't have been possible.

It may also be informative to have ASR measure LKS004, highly resolving without soul IMO. We could see if LKS/Musetec capable of producing good measuring dac, would lend credence to idea 005 purposely produced for sound vs measurements.

@sns 

my friend, why do you insist on wanting to see the measurements too? don't you trust your ears? no high-level DAC manufacturer provides the measurements made with the AP Audio Analyzer and do you know why? because such measures count for nothing with the sound result.

forget the technical data, rely on listening.

I repeat that an exhaustive mathematical modeling able to describe the variables that come into play in the audio reproduction process is impossible to achieve, the reason is simple: the variables involved are superior to the equations that bind them and the system is indeterminate.
