DAC upgrade suggestion

Actually, I like more dynamics, punchy bass and clear, transparent sound.  But the tricky part is, to a point that not to sound fatiguing.  It is more a feeling after a longer time of listening.  When I first hear the Topping dx7 pro, it sounds great.  But after maybe 30 mins, I feel it is too “noisy”, and I need to turn down the volume from my normal listening volume.  I guess this is called the synergy between the components.  I am using a Triode Lab 2A3 and Spatial Lab X5.  Both of them are very revealing.  It seems they match better with the Audio-gd.  I also try the Almarro 318 with the Topping, I don’t feel fatigue.  But I like the Audio-gd + Triode Lab More than Topping + Almarro.  
I think I have two top candidates:

1) MHDT Orchid
this has very good review by reviewer and the community.  People often comment it has a smooth, liquid sound.  
2) Audio-gd R7 or R8
this has rave review in 6moons with a blue moon award.  It is the same brand that I like, and hopefully with similar but improved sound signature.  Also, it is very flexible that I can choose a TDA1541 smoother sound, and NOS vs with over sampling.  

Forgot to mention, the Audio-gd has a in-house developed R2R chip, while the MHDT use an old TDS1541a.  Although the TDA 1541a has good reviews, but if Audio-GD do it right, a new technology should theoretically sound better.  And with the positive review in 6moons, I hope it means it is done right.  This is another pro to go with Audio-gd.

I will give my vote to MHDT Labs Orchid.

I have three DACs, the one I already mentioned and a Jolida glass FX tube DAC III and an RME ADI-2 DAC FS. I personally prefer the Orchid out of these, it's very smooth non-fatigue sounding in my system.

Just my 2 cents :-)

The Yggy is amazing - and it gets superb reviews, which rank it with the best available. 

But, the Dennafrips Terminator and Audio Mirror Trubadour also get superb reviews.  

All these are R2R Dacs, which sound much, much better than other types of Dacs.  

If you want sound, which competes with the best, these are the Dacs to consider.

I'm in the same boat as the OP. Just got a Topping D70.  It's definitely more detailed than my old MyDac.  However, I too, find it a bit harsh after a while. Maybe I just like bad DACs......
