PREAMPLIFIER UPGRADE QUESTION

My system consists of the following:

1. Martin Logan Impressions 11A

2. Rogue RP-1 preamplifier

3. Lumin U@ mini streamer with Chord Qutest DAC.

4. Bryston 4B3 Cubed power amplifier

I just purchased the Bryston amplifier and it has brought my speakers to life. From dull and listless to vibrant and alive.

I would like to upgrade my preamp and my three choices are as follows:

1. Rogue Audio RP-9-tubes

2. Bryston BR-19 which is fully balanced.

3. Conrad Johnson ET6 or ET6SE

My cables are Cardas Clear Cygnus

Any thoughts or suggestions would be appreciated.
