Suggestions for a tube pre and power amp


Dear Audio Friends,

I am writing to seek your experienced suggestions regarding an upgrade to my current stereo setup. My current system consists of Revel F328Be speakers powered by a Luxman 590Mk2 Class A integrated amp. My frontend includes a Sonic Transporter (Roon core) powered by a Farad LPS, a Holo Red streamer, and a Holo May KTE DAC.

I am considering transitioning to a tube preamplifier and a solid-state power amplifier combination. While my speakers have a 91dB sensitivity, the impedance dips to 3 ohms between 100Hz and 200Hz.

My current shortlists are as follows:

- Power Amps: Coda S5.5 Class A or Coda No. 8 V1.

- Tube Preamps: Backert Labs Rhumba, Spatial Audio Raven, or Motherlode XL.

 

I am looking for a 3D holographic, warm sound with a high level of clarity and detail. While I am aware of the general rules regarding impedance matching, I would value your insights on how these specific components might pair together. I am also very open to any other combinations you might recommend.

 

Thank you for your help.

@agbrace  Wow you have got lot of preamps. Last year I was planning to get ML523 and N534 power amp somehow it didn't work out. I assume you also have many power amps, which is your favorite power amp?

 

 

@cooperdude6 You have a very important point which never came in to my mind. Luxman have preout but it is single ended. I can try it with power amp before getting the preamp. Does preamp have lot of break in time?

@jw944ts  Thank you for sharing your system details. Good to know that it is never leaving Class A in a big room with Revel Saloon.

@lals Right now I just have the Coda, an Accuphase A–75, and a Luxman 595 integrated. Speakers are Magnepan 3.7i and KEF Reference 1 Meta. Very difficult to say which amp is best, I rotate things in and out, system synergy and amp to speaker matching I have found is very important. Source is an Aurender N200 and EMM Labs DAC2X V2. Somebody else mentioned Audio Research and Pass, I have had that combination and that is a very nice sounding pairing also.
I’m interested in a pair of Revel 328BE how do you like those? I had a pair of 228BE and unfortunately had quality control issues from the factory and the serial numbers for left and right were so far apart, nine months manufacturing difference I could never get the speakers to image very well. I liked their overall tonality, but would be picky to find another pair. 

@kevemaher I have also seen the measurements in ASR. I was not able to understand the significance of low phase. Coda amps are high current amps but I my mind was inclined to Coda S5.5 but some suggested to go with No8.I need to find out the perfect match.
Revel generally paired with ML gears in shows. and they seems to be perfect matching.
