I have owned a Tambaqui and at the same time had a customer consign a Makua with the DAC built in. Unless you are dead set on conserving space, I would opt for a separate preamp and use the full Tambaqui unit. While the preamp is very clean, it did not offer good harmonics, and its effect on the Sonics left it a bit dry and processed sounding compared to many other preamps I’ve tried.
I’ve also posted in other threads about DACs and their analog stages and have mentioned that after testing, I would never run a Tambaqui direct to amp. Its built in volume control is abysmal for a $14K unit. You will absolutely gain much (pun intended) by adding a quality preamp to the chain.
