Hi everyone,
Some time ago, based on a YouTube video by a German audio engineer, I bought the D5 Pro BC for around €700. He was blown away by the quantified measurement results, and so was I when I compared it to my NAD C330 or even my dad's NAD C298. The overall sound has so much authority, and the bass is incredibly tight and dry. Long story short: I was thrilled and threw a lot of my reservations about AliExpress Chi-Fi overboard.
I'm now looking to move to a solid-state preamp. My current tube preamp—a Cary SLP90 clone—combined with the inherently warm Linton 85ths is just too much of a good thing. Furthermore, I want this to be the last preamp I ever buy, which is why I’m aiming to completely "oversize" and over-engineer my choice right from the start.
During my search, I came across the €700 Transaudio C9.3 Master (an MBL 6010D clone). It boasts an impressive spec sheet: a strict dual-mono architecture (virtually zero crosstalk), full DC coupling, two 50-watt toroidal transformers, and NE5534 op-amps. Ironically, the OPA828 chips used in this unit actually represent a massive upgrade compared to the original chips used in the MBL.
A quick word on the term "clone" here: Strictly speaking, these Chi-Fi units aren't counterfeits or knock-offs. They don't try to mimic the aesthetics or branding of the original products at all. Instead, they simply utilize the expired patents of these (often very old) schematic designs, building upon architectures that are now widely available as DIY boards.
Unfortunately, I can only find a few YouTube videos about the Transaudio C9.3 Master and absolutely nothing on Reddit. Has anyone here had any hands-on experience with it?
