@tburdwin Keep the transport, sell the rest. Not needed. and there are better preamplifier implementations in 2025 than the PS Audio Ultra Link II
Since you’re keeping the transport, you need a DAC/Preamp with AES/EBU input, coaxial and Toslink inputs too so you can route from any of the corresponding outputs on the transport into the DAC/Pre.
I’d recommend a DAC/Pre that has DSP system onboard for seamless subwoofer integration (also has streaming capabilities built in. Get this witht he added UMIK-2 and Tripod - miniDSP SHD
Get two of this monoblock - Purifi EIGENTAKT 1ET9040BA
Analog XLR cable to link each XLR output from the SHD to each monoblock. - Balanced XLR Cables
Two of this large stand mount stereo pair with incredible imaging, tonal coherency and precision of soundstage cues - In Black or In Walnut
Stands. Get two - Custom Speaker Stand Made Upon Order
Get two of this subwoofer - Hsu Research VTF-TN1
this AES-EBU cable - Supra AES-EBU XLR cable
I assume you have speaker cables
And then use the rest of the money to dedicate to making iterative, room treatment decisions backed by science and not vibes.
