Amp to compliment Sonic Frontiers pre??

Hello

So I am trying out a buddy's Sonic Frontiers SFL-1 pre...kinda liking it alot with the Epos M5i's I have...just have to find the right tube match...I bought a Brimar CV4024 this morning so maybe that'll be the ticket!!

But, in the mean time, can anyone recommend an amp (4ohm capable) to go with the pre?? I am looking for warm, full bodied, maybe rolled off on the top...something to offset the top end brightness of the Epos but still bring out it's beautiful mids!!

Would something like a B&K ST-140 work?? Suggestions?? Comments??

I borrowed his Mitsubishi DA-A10DC which seems to be working good but could have a nicer bottom end LOL!!

Thanks kindly!!!

Sideways,

Several years ago I had the Sonic Frontiers SFL-1 in my system. The preamp mates well with an ARC tube amp.

What make and year is the 12AT7 tube in the preamp?
From the factory the preamp came with 2 tubes. One was a 12AT7A (Ei) and the other was a Signature CV4024/M8162, a Mullard tube. The Mullard was the preferred tube for my taste in the preamp. The (Ei) tube caused the preamp to sound more like a SS preamp to me.

The B&K ST-140 does not work well with 4 ohm speakers. You might like Conrad Johnson.

Actually the tube that was in there was an Amperex 6DJ8 A frame...not my cup of tea LOL!!

I put in a Sylvania for now...better but I'm hoping for more of that warm midrange bloom and big bottom end...works well for lower volume listening that I do quite often...that's when I found that Brimar 4024...hopefully that is close...if not then I can search out a Mullard!!

And I thought that B&K was rated at 105wpc into 4?? I don't know...is it going to be an improvement over the Mitsu??

My other option was to go back and buy a Jolida 1501RC...had one a few years ago...sold it and regretted it ever since!!!

Though the pin-out may be the same for a 6DJ8 and a 12AT7 the two tubes are not interchangeable.......

12AT7

6DJ8

Are you sure the tube was a 6DJ8? The heater voltage on the 6DJ8 is 6.3V and the 12AT7 heater voltage can be configured for 6.3V (heaters paralleled) or 12V (heaters in series).
The tubes application characteristics are different as well.
