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

Hi , I have a Rogue RP-1 and a Rogue Hera. I’ve milked all the performance from the RP-1 with Tekefunken G-73r tubes vibration footers and quality cables.  The Hera is a whole different beast but has the house sound. My only experience with Modwright was a KWI-200 integrated 7-8 years ago. It was very nice and well built and extremely smooth for SS. In your position I’d consider the LS-100 based on the superior tube set and that it’s tube rectified. Take my rambling with a grain of salt as I’ve never heard one. Both Rogue and Modwright have nice gear and great support. I’m a Rogue fan but I think Modwright offers a superior build quality. Thanks for allowing me to ramble and Happy Hunting, Mike B. 

With regard to the tube rectified aspect, just how important is that to the sound quality? I am not that versed in the design of tube gear. What is the thinking around the rectification aspect?

I had the Rogue RP-7 followed by the Modwright LS 36.5 in my system. Both are amazing preamps. Well built, sound similar and had similar features. I see that the RP-7 is a V2 and the LS36.5 is discontinued. The current Modwright offering that meets your criteria is the LS300 as it is true balanced design. The LS100 has XLR input but is single ended. 

+1 rrboogie as to the Modwright not being fully balanced an oversight on my part.  Also to the op rrboogie has been able to convey an opinion from actual experience. In the various tube gear I’ve had , some with tube rectification allow more than one value of rectifier tube. My experience is that rolling various rectifier tubes has allowed me to tailor my sound and also overthink things. Cheers , Mike B.

Consult Jim White (Aesthetix) via email or phone. He is helpful and quite receptive.

His Calypso pre-amp is excellent in stock form plus offers upgrades down the road.

Happy Listening!
