One day when I re-organize my DIY parts, I found an idling IVY III, Volumite, bipolar PS and some transformer here, the IVY III and volumite removed when I put Legato with Buffalo 2, as I no longer driving the headphone by IVY III but I still remember the IVY III driving my headphone quite nice, however I like the sound from legato more on line out, so I pull the IVY III out. I just want to use the volume control in digital domain with volumite to eliminate the VR and it's wiring, currently only Buffalo family and Opus can work with volumite, if the DAC board able to accept I2S and SPDIF, Buffalo 2 will be $249, while Opus + WM8804 transceiver will be $150, USD 99 difference, if you think of Buffalo 2 with very nice re-clocking with crystatek CHD950 with more path to upgrade, I can fully justify to pay more, but the Buffalo just unavailable now, Opus is the only option. And I owned a QLS QA-550 wave player and with I2S/SPDIF out, and easily powered by single rail DC at 7~9V DC, I can put them into single case and connected with I2S, powering together to eliminate external cabling. So if I dropped the Transceiver, and put an I2S enable DAC board, volumite firmware and one extra single rail PS, I can made the IVY III sing for me again. The total of the order was $55 (opus unassembled) + $15.50 (LCDPS PCB only) and Volumite firmware for Stereo Opus, the cost is well under USD$100 mark, meanwhile I can wait for a future SPDIF/I2S/DSD Mux and USB module for the future. Tonight I assembled them together and testing (not yet finalize the casing yet), the sound just WOW, as I eliminated the analog parts (line in, Volume control pot), SPDIF cabling and receiver, extra headphone amplifier and interconnect, everything is so clear and detail, a lot of information in the music that's I missed before, and I found it now!
