Do I Need a New DAC?

Do I Need a New DAC?

Newbie here to seek advice on a new DAC with a budget of up to $2K

I am thinking about adding a new my DAC so my stereo setup can play a small collection of SACDs using a 4K DVD player.

Here is my current Stereo setup

CD Player: Emotiva ERC-1 (as a transport)

DVD Player: Sony UBP-X800M2

DAC: Monarchy Audio M33 DAC / pre-amp

Pre-amp: Audio Research SP-6E (I think)

Power-amp: Audio Research VT100 MIII

Speakers: KEF104.2 (re-capped; replaced ferrofluid)

Analog: SOTA Nova V, SME3009 III, Audio Technica AT440MLA cartridge

Interconnectors and speaker cables: DIY Gotham cable    

I have a decent collection of CDs (classical, jazz, and pop) that I listen to occasionally; I have no plan to rip and stream them for any time soon.

All the equipment except the DVD player have been with me for a while.  I am thinking about spending some money in the next several years to upgrade the DAC, the CD player, the pre-amp and the speakers in that order. 

The reason to add a new DAC as the Toslink In on the Monarchy M33 is broken and I cannot connect the Sony DVD player to the DAC (the digital In is currently connected with the CD player); also, I would like to get some updated technology on DAC. 

Based on web research, I am thinking about these DACs: Gustard R26, OKto Research, Soekris DAC2541, Schiit Yggdrasil + (a bit over budget), and Hegel HD30 DAC (used).  I have yet to hear the sound of any of these DACs.  I am OK with either new or used and open to other recommendations.

Shall I add a DAC or shall I forget about the SACDs (about 20 CDs); instead, buy a better CD player or save more money to buy a better pre-amp.  Not going to invest in a dedicated SACD player for now though.

Thank you very much for your time; looking forward to reading your comment.
