Review on 🎛️ Nobsound HiFi 6J2 Vacuum Tube Preamplifier Stereo PreAmp with Digital Treble and Bass Tone Control in Black by Cheryl Brown

yeah that thing is cool. It's great that you can customize your pipes! :) Definitely upgrade your lamps, although you will see a difference. Edit: Personally, I also run an old audiophile Panasonic "Discman" so I can have some real hardware deemphasis on some old Pink Floyd CDs in the first edition. My goal was to record music with hardware accent in 24bit-96kHz in order not to lose the music. - OK FYI I'm using an Audigy RX with 24/96 Asio - The software I used to record is Sony Sound Forge 9.0. It's ok with input @ -24.4dB, the noise floor peaked at cdp @ -97.4dB (no signal). connected directly to the computer - then added this tube buffer to the circuit. now peaks at -97.3 dB. Oh my god, this thing is so damn clean! and I've done a few different recordings of "Dark Side of the Moon" with and without the "D2" and my recordings with D2 tubes with the GE JAN 5654W sound much more natural and buttery smooth! You can definitely do it on symbol glitches here, and it's just that the highs are a lot less distracting overall. - I also ordered an MCM Custom Audio (50-14820) (RCA amp) and that junk dropped my noise level from -97.3 to -73.1 which is ridiculous (it was a waste of $40). I used to recommend it, but now I'm taking it back. So if you're in the situation I was in and running an old CD through the drive with a very low line out, you're better off using the headphone out for playback or the line out for recording. and then use Sound Forge (or Audacity) to normalize the sound. (normalized to peak -0.02 for Redbook standard).
