Does a Tube Dac make sense?



I’m  in the market for a dac since I bought a Musical Paradise MP701MKII Tube Preamp few months back, does it make sense to buy a tube dac? The seller Garry is suggesting to get the Musical Paradise MP D2 MKIII which is a tube dac with a AK4490 but can be upgraded to AK4499 but I’m leaning towards the RME ADI2 which is almost the same price as the MP tube dac. I’m finding it hard to justify a $1k dac but I have read a lot of forums that suggests the RME or the SMSL M400 and Denafrips Ares II but I’m a sucker for vu meters and spectrum analyzers but if the MP tube dac is a good match for my MP tube preamp I’m willing to give it a go.

@dletch2 .. how is it any different with a tube-free DAC? Every DAC has one signature sound unless it includes different filter options (tone controls). I've heard quite a few DACs over the years and each one sounds unique. Neutral? Free from distortion? No sound of it's own? Yeah, not so much. IMHO of course.
@melvinjones,
Precisely! 
There's no neutral audio device. If a tube is a so called "tone control" so is a transistor. Just different versions of distortion. The idea that solid state is the default neutral choice is not logical.  Listen to a half dozen solid state DACs and each is different sonically from another. Same outcome with tube DACs in the same scenario.

Tube dacs make sense if you want a bit of coloration to the sound not a bad thing if that's what you are after. I had a Lampi Big 6 and IMHO was too colored only realized it after an audition of a Bricasti M1. Once heard and understanding what the tubed dac was doing I had to have a more neutral and even sounding dac, if this makes sense.
Every DAC has one signature sound
No they don't. If a DACs noise and distortion is so low it's beyond human audible threshold it's considered transparent. I've heard quite a few DACs over the years and when sight was removed from the equation I couldn't tell one from the other as long as were not DESIGNED to have a signature sound.
Understood,
Some listeners will say they can not hear a difference, with the same DACs other listeners can easily perceive sonic differences. This shouldn’t be surprising as a fairly wide spectrum exists as to what people are able to detect and distinguish. Measurements at this stage of development can't account for all that the ear-brain neurologic pathway can decipher and process.
