Entry Level Tube Integrated Amps

In the exact price range as the Willsenton R8 is the Muzishare X7 KT88. Some electronic techs who know tube gear examined both and some said the Muzishare might be a touch better and safer. Tubes can obviously be expensive, but they don't have to be. There are new tubes being made that reviewers do like such as the PSVANE Horizon tubes. What seems to separate a "good" tube amp from a "great" one are the transformers used, the quality of switches, rotary bias and volume controls and how well negative feedback is used to lower distortion. 

I think now Willsenton took to heart some of the constructive criticism and has changed the value of a certain resistor to make red plating less likely, so that is good.  The resistor should melt before causing a fire. 

I love my McIntosh MA252 integrated amp.  I love its profile, but more than that, I love the sound.  I have used it to power S/F Serafino’s, and now have my MT5 turntable hooked up, a BlueSound Node, and running into B&W 804’s.  I don’t use this system currently to power the living room, but I have in a previous house.  It is a lovely sounding piece of equipment (set up).

@grislybutter  Vincent makes hybrid integrated amps not tube integrated amps

A Decware Mini Torii would work very well with those Heresys

I use mine with some Klipsch Quartets.  very lively sound

I reentered the tube amp world a few years ago with an Olchen EL 34 for $350, it’s not bad, but not great. Now sits in my office driving Klipsch RPM 160, predecessor to the RPM 600. Sounds good enough for background musicwhile I work. 
 

Next came a Dennis Had KT-88 Firebottle, 6-10 wpc of single ended class A with no negative feedback.  I had Dennis build it with a high quality volume pot so I don’t run through a preamp. Sounds absolutely divine, layered soundstage and rich full midrange driving Vienna Acoustics Bachs in my master bedroom.  The amp can run 6550, 6L6, EL 34, KT-88 tubes driven by a single 6SN7 or 6SL7, a tube rollers dream amp. 

Then I bought a Willsenton R800i 845 single ended class A that puts out 20 wpc but with pretty strong negative feedback. It’s a beast and drives Klipsch Forte IIIs and a pair of Focal Aria 926 for a more intimate, smaller soundstage effect. I never get the volume dial past 11 o’clock. This rig is in a large, wide living room/den with tall ceilings. Playing through the Klipsch is like being at a live performance with the best recordings.

Finally came a Cary Audio 300SEI LX20 running KR Audio 300B XLS tubes that can output 20 wpc in single ended class A with no negative feedback. A Dennis Had design when he ran Cary Audio. This amp drives an older pair of JMLabs 716S. I’ve also run it through the Klipsch Fortes. The epitome of 300b sound signature! 
 

A good sample of ch-fi and US made boutique tube amps.  My recommendation would be to find a Dennis Had Inspire to drive your Klipsch Heresy’s.  He builds them by hand one at a time in Cary, NC and sells them on ebay under radioman731. They range from $2,500 for a KT-88 to $5,000 for his 300b with Western Electric new production tubes.  HiFi Huff reviewed the 300b and called it an amp for life. 
 

Best of luck on your tube journey.  Cheers!
