For instance with a tube switching from triode mode to ultralinear will be perceived immediately due to the increase power.
This has not been my experience with amplifiers that can switch between triode and ultralinear or pentode.
Perhaps you mean gain?

How does your Marantz and Aiyima compare to the ACA and Fisher?

Is Mr Helmholzs work discredited ???
Yes when AS came into existence. 😉
Before Novak and later Thiele and Small knowing a box could be used as resonator didn't automatically mean good sound.
Open baffle/panel speakers have existed for a very long time, probably all the way back to 1924? and the first moving coil loudspeaker.

So I added the JEM Performance Capacitors and I am challenged to hear a difference. Only one side has been upgraded for the moment. .. listening to mono recordings to compare. I'll have my 18 year old give it a listen, maybe it's old ears. Dunno...
Any updates?
Did you or anyone notice much difference with the new caps?

It would be "putting Gold Hubcaps on a Volkswagen" ...I assume most members here are like me and given the choice between a crappy non musical subwoofer or no subwoofer the choice would be no subwoofer.
So maybe more like putting large spongy wheels on a VW.

See Overview section.
2 subwoofers with speaker level inputs will do. 😉

I haven't. But funny thing, I just saw your message and also just this second sat down to the PC to start looking for a good sub. My DAC/preamp has a pair of balanced outputs available; or I would have to use a splitter on the RCA's to connect to a subwoofer. Please share any thoughts you have about how it should/would/might work. Thanx. Rob

Not a lot of XLR subwoofers so xlr to rca cables for sub, rca for both with Y cables, or subwoofers with speaker level inputs.

Thx 83 LSIs for your reply. Means a lot. Was the idea to drop the gain, because the horns are so sensitive/and/or bright sounding? You can tell I have a lot to learn.
Were you able to take a look at the link and the comments in the 3rd paragraph?
Horns bright? The crossover must be out of spec or a bad design.

Besides the tubes, does anyone know what modifications are in the Horn Mono's that make them more suitable for horn speakers? That would be good info to have to teach me more about horn speakers and what I have with the H-IV's. I
Thx, Rob
Input sensitivity: 9V
18dB less gain than their other amplifiers.

DIY but should be able to find someone build it for you if needed. Built amps often come up for sale.

Victor might be able to help: https://www.vkmusic.ca/
Dennis Had Inspire (search on Ebay) will build one of his for you.
He is retired after starting several successful businesses including Cary Audio.

I have the same issue with a brand new set of Heresy IV's.
How long have you had them?
How many hours would you say you have listened to them?

No front left & right preout and no phono preamp.

It is also possible that someone may have at one time glued the access cover closed on some speakers, causing grief for the next person that wanted to get in.
I had to make new ones after I destroyed the original panels because they had been glued.
The guy that did it was a wood worker/finisher and obviously not a speaker guy.
He put the 17? screws back in and fortunately only used a little glue near the edges so I was able to get it off without damaging the wood inside.

now what "line stage" refers to.
Normally a preamp with gain and multiple inputs, but no phono stage.
In your system I assume you are using the Vincent PHO-701 directly into the Elekit 300B which is an amplifier with an input level control.
Looks like it should work, only one way to know for sure.

In REL's own words:
"While it might trade off a touch of the speed, clarity, and deepest bass that our standard models, like the T/9x, are known for,......"

The Denon is 45W/8 ohms and the NAD is 50W/8 ohms.
Why is the Denon inferior quality?

I thought maybe they are a little squeaky so some oil would be included.

The real problem I see is the difficulty designing for both modes since finer tuning is different for triode and ultralinear, it takes more than just a simple switch between the tube and OPTs.
FWIW I had a Line Magnetic LM216IA that I preferred in triode.
At my listening levels in my system there was no difference between 22 watts and 38.
