Anyone have good success using a tube speaker power amp or tube speaker integrated to amp with their headphones? Also is the fact most speaker amps Run at an 8 ohm impedance a disadvantage compared to some headphone amplifiers that have a selectable impedance for example for a 300 ome headphone
I run a Primaluna Prologue 4 tube amp to run headphones occasionally (mainly use to run my power-hungry Modhouse Argons) with good success. It does have a little more background noise then a typical headphone amp but sounds great otherwise. The background noise is not an issue with typical music but can be noticeable when listening to classical during quiet passages. The sound stage is also huge when running this amp.

I'm using Rothwell in line xlr attenuators. they come in -10, -15 and -20db options. another alternative is to reduce the output volume of the dac (if it has volume control) or to reduce volume in the digital domain eg using the headroom dsp in Roon.
It not only puts a load on the amp, but it also has a defeat-able resistor attenuation network. There’s a calculator to tell you what resistors to use to achieve the level of attenuation you want.

Egads, this thing is still floating around. I highly recommend removing the entire upper left portion of that schematic. A 4-pole output should never never go to a 3-pole output unless you know with absolute certainty that your amp has a shared common ground on the negatives. Hell, if you already have one built, snip off one of the negative legs going from the XLR4 to the TRS to eliminate any chance of oopsies. It will make zero difference to the TRS output if you have a common ground unbalanced amp.

If looking for a 300B or 2A3 speaker amp that is also superb with headphones take a look at Elekit TU-8900 I have been using one for about 18 months with a Chord Dave front end its excellent with both my Senn hd 800 and Hifiman he6 best I've heard both sound in 9-10 years of owning them.
Stereophile have a recent review which includes use with speakers and headphones.

I had the tu8600 I found its a bit to neutral for my taste. Im looking for something more warm, euphonic and 3d with no negative feedback. I am considering the tu8850 though cause I think you can turn off the negative feedback and then i can use el34 tubes.

The TU8900 can also run with or without feedback it's done by simply moving across a jumper tag. There is a very noticeable change in the sonic presentation between having feed back on or off. One of the things I really like is that you can have four different presentations feed on or off with 300B and then the same with 2A3.
All four different presentations are enjoyable different reasons but I tend to listen to 300B no feedback the most.
Still it's not a warm lush sounding amp but certainly not neutral with feedback off.
What output capacitors did you have in your TU8600? If your after a warm textured euphonic sound you should definitely look into running a paper in oil capacitor. In my TU8900 I ran it for probably six months with the V-cap cutf copper teflon but the last six months have been using Russian surplus K75-10 this is a hybrid paper and mylar in oil capacitor which has a unique character this is bypassed with a Duelund JDM silver foil bypass cap. I've used pio capacitors in the past and one of the first thing I noticed straight away was a familiar ease of presentation compared to a modern mkp cap.
