Two V5 dual Op amps made Project Tube box phono preamp two class higher. Originally op-amps in this preamp were TL 072. I changed them with LME 49720, then sounds much better, detailed, airy… But with Burson V5 preamp sounds deeper, with more extension, authority, body of instruments… Only “problem” could be that LME sounds with more details in mids, highs, because V5 have more Bass and that “hide” some details for our ears…
