GR70 as preamp or amp?

Hi all,

I am new on this audio world and started everything with the FOSI gears (ZH3 and GR70), which had a good price here in Brazil.

Talking with some guys (some of them reviewrs), using the GR70 as preamp called me attention. But the question is: does the ZH3 "kills" the warm signature or just amplified it?

Setup 1: ZH3 (RCA) > GR70 (RCA) > Speakers;
Setup 2: GR70 (RCA) > ZH3 (XLR) > Speakers.

The diff is GR70 as preamp when behind the ZH3 or after. Some forums and people told me that ZH3 does not "kills" the GR70's signature, but speacially with headphones I think there is a difference when I plug them in directly in GR70 and switch to ZH3. ZH3 sounds more round and clear, so for me less lively, while GR70 plays in a more immersive way. There is nothing scientific here, only my ears (and lack of experience).

Nowadays, I am using the Setup 2 and really enjoying. Samba, Jazz, Bossa Nova and Classical are the favourites here. It has been crazy how songs I knew since I was a kid are being redescover.

Anyway, I am really trying different ways to use the GR70 (and ZH3) to see if ZH3 "kills" the warm signature or just amplified it both in headphones and speakers.

Hope we can share some ideas.
