Modwright LS-100, Rogue RP-7, Aesthetix Calypso


I currently own a Rogue RP-1 and am looking to upgrade. Budget is ~2,500 (used). I have shortlisted the following 4 preamps:

  • Rogue RP-7 (V1)
  • Aestetix Calypso (Standard)
  • Modwright LS-100
  • Modwright SWL 9.0 AE

In order of preference: smoothness, dynamics, moderate to light warmth, detail, soundstage.

It is being paired with a Classe CA-2200 amp, Laiv uDAC+uDDC, and a pair of Audio Concepts Jaguar 2000s. 

I like how the RP-1 has the dynamics and detail of a SS but also adds some tube warmth and smoothness.

Would love to hear your experience with any of these 4 preamps individually, how they compare, or how you would characterize their sound.

Thanks!

How about the Cary SLP-03 compared to the Modwright or the Aesthetix? It can be found for very cheap. I would love to go for the SLP-05 but it's well beyond my budget.

I had Fisher 80AZ Mono Amps for many years, never changed the 5V4G rectifiers, they always tested good. 

I had no idea different rectifier tube would alter the sound, until

My friend had Kara build him a Preamp

And she sent both new and some spare used tubes, including a spare Rectifier. We were quite surprised at the difference it made, one sounded far better than the other.

 

Just to close the loop on the thread, I ended up finding an RP-7 for a good price on AudioMart so I snagged it. I still want to compare it with an LS-100 or Calypso one of these days but that will have to wait.
Good news is I can use the 12au7 tubes I bought for the RP-1 to do some tube rolling. The RP7 came equipped with the 4 stock ECC802. I purchased previously for the RP-1: Amperex Gold Lion (new), Tung Sol (new), "Mullard" (new), RCA Clear Top (NOS).
