If you want a wide open sound, Ayre uses ZERO feedback, fully balanced and can be found for very reasonable prices used. I started with a KX-5 Twenty used and liked it so much I upgraded to a KX-R Twenty used. Their products are so well designed that they are top notch for 20-30 years while others "catch up." Happy listening!
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.
