The Octave Phono Module is a versatile product, with the added luxury of being able to upgrade later on because of the modular concept. I used the integrated version in the Octave HP500SE, in which the Octave Phono was based on, and was totally satisfied, for years. I put the Einstein and ASR head to head with the Octave and stayed with the Octave. It was not until I heard the Aesthetix IO Signature, that I was finally swayed to make a leap to another phono stage, which cost me more than the Octave Integrated.
I have also heard great things about the Allnic.
