Customer Reviews
As awaited.
Out of the box a very neutral clean sound.
Used with 16mm Films, mono magnetic and optical tracks. My preference is with the LM4562NA op amp which gives a more mellow sound than the standard op amp. A much improved weighty sound with this small powerful amp. Very high volume possible.
Running two 8 ohm speakers in parallel 4ohm mono load.
Very good construction. They work all day long and are thermally stable. After warm-up time / 30-50 hours / the sound is dynamic and rich in details. A dedicated DAC in a balanced version would be useful. Thank you and best regards.
Beautiful sound and build quality. Easy upgrade with just 1 opamp. I highly recommend you do this. Easy to open case (start with removing the volume knobs).
I had hoped for
-a high pass filter for small speakers to combine with...
- volume regulated sub output.
- auto off, not just 12V trigger
- sub out hf cutoff frequency is rather useless.
Why I love it: absolutely fabulous sound quality, great design and high power efficiency. Small and well built. From the full aluminum knobs to the no-slip feet.
One of the best amplifier ot there
