As a fourth option, try a Schiit Kara or a Freya+. Way cheaper than the mega buck units. After trying it, you may decide to keep it. The gain options on the Kara are a deal maker. No more turning the volume knob 1/1000 of a turn and the volume is too much. Having a low/high gain preamp is indispensable.
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.
