Anyone upgrade to the Merason Dac1 mkii?

Today is still possible to find Merason DAC1 mk1 brand new. Is it a worth purchase? I ponder between the DAC1 and the Aqua La Scala. How much would it cost upgrading the DAC1 to mk2 specs? Thanks a lot.

@bluethinker thanks a lot! are you familiar with the Aqua La Scala? It seems is appreciated for being relaxed and musical too. It has the advantage of having tubes. I don't like the aesthetics of it so I'm naturally for the Merason if the SQ is not too far from the Aqua.

I have bought a DAC1 demo from a retailer in Paris. They say it’s a mk1. I think it’s a mk2 since it has the aluminum chassis in brushed grey. 
the sound is as widely described by user and reviewers. 
I had read the DAC1 was superior to the MSB discrete, which I own. Unfortunately that’s not the case. The comparison is not apple to apple as my MSB has the streaming renderer module and the DAC is connected to the router via Ethernet and talking to the Nucleus without usb. The Merason is connected straight to the Nucleus via usb. 
it may be the reason for my disappointment, however, details, clarity, precision, soundstage width are much lower vs the MSB Discrete. It is like the typical feeling of a blanket thrown on the speakers. My speakers are TAD ME1 and the amp is a Vitus RI101mk2.

will a dedicated streamer make such a big improvement to deliver results equivalent to the MSB discrete? Obviously a richer and fuller sound won’t easily bring a precise and detailed sound presentation with strong dynamic. Or so I thought. 

I have added a passive preamp to the chain and it was a metamorphosis. I like very much the DAC1 now. And the MSB discrete sounds over detailed and too brilliant, fatiguing to me. The magic of changing pieces in the chain. 
I just wonder if I actually own the DAC1 mk1 or mk2. The dealer swears to have sold me a mk1, however it has the full aluminium look vs the glossy faceplate and metal chassis of what I have always seen. 
 

@facten yes that’s what I intend to do. Maybe it’s an mk1 and they were already releasing new chassis.
