DAC recommendation for DSD input


Hello-- 80% of my listening is streaming local DSD (64-256) files via Roon. My current system is Roon Core on an iMac Pro making its way to a Sonore Optical Rendu which is connected, via USB to the DAC in my Hegel H390 integrated which feeds Magico A3 speakers and a pair of REL S/510 subs.. There is nothing at all objectionable to my current system, nonetheless, I am wondering if an external DAC might be an improvement over the H390's DAC and if that is a worthwhile spend.  I am space constrained so I must stick with an integrated (pre+amp), but do have space for a DAC and the Rendu system.

I have spent hours researching many of the newer and older DACS, including the cheaper "Chifi" DACS (Topping, Gustard R26 and X26iii),  T+A 200 DAC, PS Audio Direct Stream MKi2 and Mola Mola Tambaqui (used) and other DACs in-between (Denefrips Pontus and Terminator, Holo May, Wyred for Sound 10th anniversary, etc).  

I would rather spend $5k-$10K for a significant improvement as opposed to  $1K-$4K for no or a slight improvement. My hope is for more resolution, more musicality, less high frequency fatigue, tighter bass.  Is it unrealistic to expect that an external DAC will bring a significant improvement?

My system is in a decent room, but there is little to no choice in speaker placement or room treatment opportunities.

I have a chance to audition the T+A 200 DAC and the Direct Stream MK2.  In a previous system, I had an MSB Discrete stack which was nice, but I'm not sure that would be the worth the cost today.

What type of DAC (chip based, FPGA, R2R, OS/NOS) is more structured to DSD input?  I've almost ruled out R2R, but could be mistaken?  The deeper I look, the more confused I get.  

Thanks for any recommendations or advice.

Thank you jsalerno277-

Funny you mention it. A server is in my upgrade plans, I thought an external DAC may provide a larger improvement so considered doing that first. The server will happen either way eventually. And if the DAC is a Tambaqui, it will definitely be pre-owned :).

My experience: About four years ago, I purchase the phenomenal Hegel H590 integrated amp, which I had no intentions of using it’s internal DAC (I heard it’s internal DAC at the dealers). Like yourself, I’m also space restrained. After further research, to save space, I decided that I wanted a streaming DAC. My budget for a DAC (pre-owned) was approx. $5000-$7000. I was aware of several excellent DAC options out there on the market, but I had on way of gaining access to all of them. I started my search by first visiting my local high end audio stores and listening to what they had available for in-store auditioning. I even traveled some distance to be able to audition other brands that were unavailable at my local audio dealers. In the end, it came down to two choices, the dCS Bartok streaming DAC, and the Ayre Acoustics QX-5 Twenty streaming DAC. I chose the Ayre Acoustics streaming DAC (best value) and never looked back. Note: I couldn’t get any of the dears to let me borrow any of the DACs for in-home auditioning, so it was absolutely critical that I made the extra effort to do the extensive in-store auditioning that I did. I’m extremely happy with the choice I made. Happy listening.

Thanks kennymacc.  I agree, it's very hard to get in home auditions anymore and buying pre-owned is a crap shoot and waste of time if the equipment isn't satisfactory. Upgrading audio is not as much fun as it used to be :)

 

@mintakax ,

For the price you have mentioned, T+A would be the best choice for a DAC that can do pure DSD. Especially because you use Rood to upsample everything to DSD 256. Try to audition that and see if you like it. Hope you get to audition a "burned in" unit, rather than a fresh one.

I was finally able to utilize the I2s connection on my DAC (a relatively inexpensive Gustard X26Pro, which is well engineered) by adding their DDC, the U18 (also pretty reasonably priced). I have a high end system which is mainly focused on vinyl playback but wanted to up my game on the digital front without throwing a lot of money at it. The digital front end is far less $ than my vinyl playback set up but with DSD through the I2S connection using these modest components, is quite impressive- I'm hearing far more of the acoustic space in recordings, the attack and decay of harmonics, the drum skin sounds- none of which sounds clinical. I had a long, perhaps unjustified reluctance to use digital for anything other than work or background music but now this is listenable. Of course, I've spent a few dollars buying hi-res downloads, but it has added an additional dimension to my listening experience. 

Do the T+A hdmi ports support I2S?
