Dear @mglik :
Dear @mglik : I have no doubt that you love the Zesto unit that's a tube phono stage design.
Why LP analog alternative needs a phono stage? mainly to apply the inverse RIAA curve eq. and in second place to amplify the cartridge signal.
The inverse RIAA curve eq. should mimic the RIAA curve eq. for we can achieve a flat frequency response. This means with no frequency deviations.
The RIAA eq. is a heavy equalization process that goes from 20hz to 20khz and the eq. from around +,- 20dbs ! ! where any single deviation on that curve affects almost two octaves during the inverse eq. phono stage second process.
From some time now a good phono stage design normally comes with an inverse RIAA deviation of: +,- 0.1db but the Zesto comes with higher frequency response deviation: 0.5db that means it has a swing of 1db that's is to high and that puts additional colorations/distortions to the already inherent colorations/distortions generated by tubes.
The inverse RIAA eq. curve is critical to achieve or to stay nearer to the recording. Normally with tubes is extremely hard task to be " there ".
Yes, tube alternative is an option to the SS alternative.
