I'd reconsider used. Companies like Audio Research, Conrad Johnson, and Zesto make preamps that will perform reliably for decades and outperform lower end models.
Seeking a Tube preamplifier
I currently have the following system:
- 1. Martin Logan 11A Impression Loudspeakers (hybrid electrostatic)
- 2. Bryston 4B3 Cubed power amplifier 300 into 8 and 500 into 4
- 3. Bryston Bp-19 preamp recently purchased
- 4. Rogue Audio RP-1 tubed preamp backup for BP-19 preamp
- 5. Weiss Dac 204 with Modwright Linear Power Supply
- 6. Lumin U2 mini streamer with S Booster linear power supply
- 7. SVS Pair of SB-4000 subs.
I like the Bp-19 preamp. The sound is refined, detailed and clear but it is missing some of what a tubed preamp delivers. I switched to my backup preamp which is a tubed Rogue Audio RP-1 entry level and noticed that is wasn't as resolving or crystal clear as the Bryston BP-19, but I noticed that a vocalist projected air, depth and a richness that I did not find on my solid state preamp. On a track with a guitar there was a bloom and decay that I didn't notice on the solid state. Now I was thinking what about a tubed preamp that delivers both the positives of a solid state and tubed preamp? My maximum budget new only is $7500.00. Only need a linestage as phono is not required. In any case, I started looking at the entry level Conrad Johnson ET6SE, but confirmed with manufacturer this morning that there is no way to control the balance on their entry level product. I am disappointed, but my seating requires the ability to control the balance. I was also looking at the Rogue Audio RP-9, but their product uses a 6H30 tube which may be difficult to obtain in the future. Any suggestions or thoughts would be appreciated. Thank you.

You have gear that is above your RP-1, so that’s an issue. I am curious as I have an RP-1, have you changed the two 12AU7’s ? A nice pair of Tekefunkens will make a huge improvement. I also recently acquired a mint condition Hera. The Russian Super Tube’s are pretty much unobtainable, but EH gold pin and Sovtek are easy to source. Look up @mulveling on this site, he’s very knowledgeable on Rogue and gives very sound advise. Rogue’s support is first rate as I just had my amps upgraded to Dark status during a repair. My friend has better gear and more money than I and he progressed from Rogue, to Bryston , and now McIntosh. If I had the Cubed like you, I’d consider the Hera , Cary , and definitely the Zesto. Upscale has the Leto 1.5 on sale for $6K , give them a ring. Happy Hunting, Mike B. |
@kjl1065 Since your amp has balanced inputs you might consider a preamp that has balanced outputs. The advantage of going that route is, if the balanced line standard (known as AES48) is supported by the preamp (many high end audio balanced preamps do not, FWIW) then you get less artifact from the interconnect cables. If you've ever auditioned cables side by side and heard a difference, that's what I'm talking about. So if you're inquiring about such a preamp its a good idea to ask the manufacturer about this. There are balanced tube line stage preamps available well within your budget. |
