Yeah, the itch. It's mainly psychological. The biggest improvement I can make is room treatment.

This may be a totally bad idea, but thought I'd solicit opinions. Balancing volume levels across multiple streamed recordings in a playlist is a pita. Could a passive preamp with remote volume/attenuation be placed in the chain without significant impact on the sound quality?
The chain is Denefrips Pontus DAC to LP-2030 Preamp to Inspire KT88 SEP. If it's not a totally bad idea, where would it go in the chain - between the DAC and LP-2030, or between the LP-2030 and the amp? |

Anyone know the input impedence of the LP-2030 preamp?

From Dennis, "Oh, there is a fellow inquiring the impedance of the LP-2030 … The input impedance of the LP-2030 is 57K and the output impedance is 3.3K. The LP-2030 will drive into as low as 10K loads at full frequency response."

@bearcity, thank you very much for that info.

I know this is borderline blasphemy, but…
I have a lead on a used 2030 preamp that I would like to jump on. However, my speakers are relatively inefficient, so I’ll most likely need to use a SS amp that has a little grunt. That being said, what kind of specs do I need to be looking for as far as what might work well with the pre? From what I read, it’s pretty flexible and should drive most anything. Thanks in advance. |

Are there WE tubes that will work in the 2030 pre and what would the model numbers be?
Thanks. |

Other than the voltage regulators and the rectifier, the LP-2030 uses 01A, 12A, and 71A and their variants. There were some Western Electric RCA 01As made and there could be others.

Thanks for the reply. As a 6V6’er owner I am wondering if someone who knows their tube combinations would be willing to throw together a simple chart showing which rectifier and driver tubes can or should be used with a certain power tube pair. Currently running VT170’s with a 5AR4 and a 6SL7GT all TUNGSOL. Ready to try tube rolling but not sure what to pair up. Thanks in advance for any help you all can provide.
