Desire to try tubes

I suggest trying the Rogue series from $800 to $4,000 for easy use and it is not necessary to be an electrical engineer to use.  These are integrated amps and I also like the ones that have a tube 'pre-amp' and non-tube full amp.  These are the least fussy and give the richness of tubes without the many other hassels.  I have a Peachtree X-1 hybred integrated amp that is my favorite at 440 watts per channel.  I also have a nice Vincent 701 pre-amp for my turntable that features 1 12AU7 tube that really pumps up the vinyl that is further tubed by the 2 tubes in the amplifier 'pre-amp'.  This amp is not longer available new. 
 
Atma-sphere is built in Minnesota and run by really great people to work with and the producer of one of the best series built in the U.S.  A wide range of choices and they build to your specs and needs.  These guys will even send you a unit to try out before you purchase.  This is hard to beat.  I think they know once you have heard their amps you will park it in their lot.  If you talk with Ralph he will make it easy.  See the opening video on their web site.  My next amp will be from Atma-sphere where they will build a capable fully tubed amp with a tubed phono stage preamp built in for under $2,500.  You should at least 'test drive' one of their products.

You said what I have been saying about @millercarbon for a while. He is an opinionated shill and if you cross him you are a dope. He’s the dope. All he does is post. I don’t think he ever does anything else. Watch his post count, it goes up significantly every week. He posts just to be a dippy tool. I’ve got your back @skypunk.

@rcronk I hear you on trying Atma-shere. I’ve been keeping an eye on his stuff for a while. Someday I’ll be able to try it. Got to get some speakers that match up with lower power amps first.

I did the Rogue trip with their Stereo 100. It didn’t match up with my speakers very well and had terrible distortion. I tried to get relief from the dealer and Rogue with no success. Ended up trading it for a non-American brand that sounds great. Only had it for two months.

If you still use the Heresies, and they are still 96db sensitive after your mods, and you want the “tube” sound, you need single ended triode amps. Buy used, or buy a kit, to save money (Bottlehead may be a good place for a kit) but nothing touches SETs for glorious sound. Speakers need to be efficient, the Heresies are, but nothing else can match that sound. I built my first one 20 years ago, it still works, and I have never looked back.

I run my highly modded Klipschorns with Coincident Turbo 845 SET,  Prima Luna Dialogue Four (modded with Takman carbon resistors, Miflex and Mundorf capacitors) and custom built 300b monoblocks. 845 tube way more power than you need for klipsch, still great immediacy, performers in room feeling. PrimaLuna use EL34 tube, lush, beautiful, my favorite push pull tube. 300B tube, maybe the most romantic tube. Can't go wrong with 845 or 300B SET amp or EL34 push pull, especially if you can run in triode mode.
Stock Klipschs will work best with the more romantic tubes IMO.
