I had been happy with Rogue Cronus Magnum II for 6 years.
With tube rolling it is a very good amplifier.
ST100 is very similar to Cronus Magnum II.

Tube amplifier suggestion for 101 dB speakers
Hello All,
I've been using the Tyler Acoustics PD30s with Classé Sigma solid state preamp and amp combination.
These speakers have two 15" woofers and a horn tweeter, 4 ohm, sensitivity 101 dB.
The above combination is not the best, especially for complex rock music, the highs start to distort, they are harsh, just bad. Never had tube gears, but after reading a bit, these speakers apparently scream for tubes. Actually somebody brought over a hobbyist-made tube amp and yes, the speakers were tamed.
I'm willing to switch to a tube amp but prefer to keep the ss preamp.
Can anybody recommend a few good tube amp matches here, for a max of 3K new or used. Room is just a good medium size. I want something that I can keep for many years if possible and being somehow flexible to tube rolling.
Thanks.

Even if your speaker has a high efficiency, I do not recommend small power SET amplifier to drive two 15 inch drivers. You may try this one as a starting point. https://www.audiogon.com/listings/lis9b270-line-magnetic-216i-tube Later if you can afford more, then I recommend Line Magnetic 508. https://reverb.com/item/17478397-line-magnetic-508ia-single-ended-triode-vacuum-tube-2018-black-clas... I am happy with Line Magnetic 508 for 6 months. https://forums.stevehoffman.tv/threads/new-line-magnetic-508ia-integrated-amp.542333/ |
https://www.audiogon.com/listings/lis9cag6-rogue-audio-st-100-tube The used ST-100 could be best starting point for you. If you change stock 12AX7 to Telefuken( around 200$ per pair) and 12Au7 to Amperex NOS (around 120$ per pair), it sound very nice. Tungsol KT 120 is good and not much choice for tube rolling. It is not that difficult to adjust bias manually. Once you do it, it keeps the value for several months or more. |
Dear Op If you are serious, then go for Line Magnetic 508 even if it means stretching your budget. https://reverb.com/item/17478397-line-magnetic-508ia-single-ended-triode-vacuum-tube-2018-black-clas... I am driving my 99db/W speaker (Lansche 4.1) with Silbatone 8W 300B SET and Line Magnetic 508 48W SET to get the most out of it. http://stereotimes.com/speak112410.shtml With Line Magnetic 508, I have more headroom than Silbatone although Silbatone is more transparent using exquisite silver foil output transformer. After you buy it, if you replace SN7 with Sylvania 1944 Nos Vt231(around 150$ per pair in Ebay) and SL7 wih Mullard EC35(around 125$ for single tube), then it sounds excellent. Later you can also replace 300B and 805 with new production Chinese tubes called Acme series or Shuguang Treasure . |
