All RME ADI 2fs owners really need to spend the money and throw out the switched power supply and get a linear supply. The very first evening with my RME I switched out the power cable with one I built with Furutech plugs and cable I purchased from VH Audio and was pleased with the improvement; was the PC I was already using on my Bluesound Vault 2 so I ordered more parts and built another. Was probably a month later I was watching a YouTube video off Kevin Deal on the Sbooster supplies and made my mind up to change out the PS regardless of what the manual claims as it will not make a difference. After researching a little I settled on Teddy Pardo from Israel. Shipped to the States only took a couple weeks and with shipping it was under $400. The improvement is well worth the cost, actually a bargain and a must in my opinion. With the Teddy, the RME is more open, stage greatly improved in both width and depth. The bottom end even with the switched supply is very good, but with the Teddy it digs deeper and tighter. The sound overall is fuller more open, lower noise floor with greater PRaT. It’s just hands down superior with the Teddy
I run mine balanced out with Nordost Frey 2 and PC is a WyWires Silver Juice II Digital Series. The combination of cables and Teddy on the RME is very natural, not at all bright or fatiguing. Top end is exceptionally clean but not bright, or soft, but honest. If you’re looking for a DAC to roll off the top end or color things then this is not it, but I suppose pick another filter and mess with the EQ. and you’ll can get there. I run the Sharp filter and don’t mess with the EQ and find it’s not at all bright, edgy, or exaggerated running direct. Can’t give the RME with Teddy Pardo enough praise.
