TOPPING D30 Upgrade the IC op.amp with RARE the NOS Burr-Brown / it is why I chose D30

It is answer from why am I chose the D30. I can do more tweaking with D30. Nice board. I have desoldering the OPA2134PA on the d30 board, and soldering the Socket 8pin gold plate for able to change with other op.amp. In here I am trying my NOS BB AB312 OPA445BM. It is old single op.amp original from Burr-Brown , long times discontinue and rare at now of genuine from Burr brown (before Texas Instrument). Make be dual mono with the mono to dual op.amp converter dip8 pcb. A song from new album Temptation ( MQA-CD) of Chantal Chamberland. Track 6. I Put The A Spell On You. It is a nice album and have a lot good Songs and good recording, I heard her voice like Diana Krall but with difference genre music. Like on the Temptation.
