Even if you decide to try a different dac,I agree that that the stock tubes in the RP1 are known for a clean modern sound and will continue to hold you back from the presentation you're looking for.I like RCA Cleartops in mine, a touch of tube warmth with a more organic sound.Think about trying different tubes before changing equipment.
UPGRADE PATH FROM CHORD QUTEST
My system currently consists of the following:
1. Martin Logan 11A impression hybrid electrostatic speakers.
2. Bryston 4B3 cubed power amplifier
3. Rogue Audio RP-1 preamp
4. Lumin U2 mini transport streamer
5. Chord Qutest Dac
Happy with the sound, but on many tracks on Qoboz the sound especially on rock leaves a lot to be desired. This could be the function of the source itself (the recording) is poor. Would a better DAC yield more detail and better sound? My price limit is about $5000.00. Not looking to buy used. Wish to work with a dealer because I have found them to be incredibly helpful. Also looking for a company that provides phone customer support. There is nothing like a conversation or a discussion to solve an issue. I understand that my view is a minority view out there. As we are in a self-service world. But I am used to a person picking up the phone and asking how can I help you? Any thoughts would be sincerely appreciated. Thank you.
