Phono Preamp. With transformer or fully active

Dear @terry9  : Well, part of the second post and only an opinion.  I think that I have not exactly a misunderstood as you said but that I did not be specific about. Never mind, your post welcomed.

Hi Jeff,
I can’t answer your question directly but have decided on a Zesto Andros Deluxe that uses 4 internal step up transformers for the MC stage. I don’t yet have my Zesto but have well heard the original Andros at RMAF. It uses two transformers internally for the MC stage. The Zesto sound is super clean, warm and natural sounding, Their room was, by far, the best sounding room at the show. And their system was fairly modest. Not expensive at all but the Zesto Andros made the room sound beautiful. I believe SUTs, in general, make for a super quiet and detailed sound. They are, by far, the best way to step up to MC from MM. And it is, by far, preferable to have them built in. The extra IC is problematic and it is safe to assume that when internally built in, they are a perfect match for the MM stage. My vote is for built in and Zesto. The Andros is modestly priced at $4700. And a big plus is that the Zestos are, IMO, absolutely lovely to look at. They are the best looking component there is... IMO.

Mglik;

4 separate transformers as step up for ?   4 inputs ?    All Mc ?

interesting

@rauliruegas 

very interesting on the concept of transformers 
it does make sense 

so, As a general rule 
Transformer step up provide softening of transients ? Vs full active ?

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.
