Thanks for the conclusion. I was thinking about it for few days, and that was the conclusion I came to.
I am quite happy with it! And I got my DX7s few days ago new for 324 USD which I think is pretty good price. But I thought, since I am planning to buy THX headphone amp either from Monoprice or Massdrop anyways, I thought I would be better off investing in standalone DAC.
But I think I will just keep DX7s. I like its functionality, sound, and design. It’s just that down the line when I do get the amp, I have to use Y splitter for my XLR output since my power amp for my speakers are also using balanced input. I just wish I can find good headphone amp with balanced input that also has preout in XLR.
But I think I am asking for too much
I only had time to test DX7s with my 712Pro. I still have to test it with my HD600 and Sony Z7. I really liked it with my 712Pro though.
Well the SMSL SU-8 and the THX 887 are going to cost you almost double that (about $1,000.00 in Canuck Bucks). Remember the 887 should have regular availability, so you don't have to buy it right away. Use your DX7S for a few months with all of your music and all of your headphones. Then see what you feel like doing in the new year.
The only problem with that strategy (for me at least), is Black Friday sales and Boxing Weeks sales.
