Tubeyist sounding Pre-amp?

in the Cary line the spl94 was better imo then the 98 the 94 had tube rectification the 98 had moved on to SS. I had a 94 slightly moded one  with AudionNote caps and it was very musical and warm. I liked it better then the 98 but hard to find one now.

Most preamps that use multiple 6sn7 tubes are a good example . 
Don't sax makes a exceptionally hoof preamp for under $3k spend the upgrade 
With better output caps .

I would strongly advise not to jump on CJ preamp if you're over 150lb.

What pre-amp has the most tubey sound?

The one with the most 2nd harmonic distortion, or you could have one with mircophonic tubes that gives many the false impression of "wow listen to the euphonics" .

Just find a tube unit from the early 1960s and put in some worn out tubes. Get as much distortion as you can. That will make it sound "tubey." Great, fat, bloated, lacking transparency like trying to read fine print through a layer of mud while wearing a welder's mask.

Otherwise, buy a modern neutral tube preamp and enjoy the quality of fine musical reproduction that well-designed tube equipment can deliver.
