LOL all is good UNTIL you get a noisy valve or you go deaf and can't hear the noisy noise floor.
87-92% is a VERY efficient speaker and with care NOT to noisy. BUT above that. Mercy.
I can here the HISS in Antioch, CA from El Paso, TX, make that Atlanta GA..:-) It's a loud one..
~~~~~~~~~~~~~~~~~~
OK Fair, and interestijng
So what you are getting at
is if one the 12 KT88;'s in the Defy starts to go bad, which some are failing now as I type, they go dark, cold, and so i pop in another, whether its a mtach I have no idea.
They have some 3k hrs by now i'm guessing.
So a bad cranky tube may cause issues, Got it.
Might need to sell off the Defy,,,ahh but can't right now you can't give a heavy amp away, nothing is moving,,,But I may keep the Defy as backup, nothing more,,, and add a Dynaco ST70 EL34, takes only 4 EL34's, = afforadble to retube.
**Hiss factor*** Yeah I can understand if the sensitivity is over say,,,97db.
I think, not sure the Vox are like 97db, .
So hiss may be an issue,
Got it.
Higher sensitivity is good, but also picks up any flaw throughout entire system, Got it,.
BUT OTOH,
Higher sensitivity allows the new high tech JFET opamsp in the Jadis DAC, now to be herad, Takman REy metal resistors can now be noted via the higher sensitivty,. Mundorf caps, can bring forth their magic, Navships cables throughout entire system can now be heard.
Lower sensitivity , 91db lower, these speakers block and tweak/mod/upgrade fro being voiced.
Argue all you want, I have noted this in my experiements.
Its all based on actual testing.
If I need a EL34, I'll add one,
We will have to wait and see how the driver responds to different amplifiers.
Hopeful the Jadis will be quiet and a success.
There was a time when the Jadis had hum in one channel,
WE swaped out the main internal wire with navships silver copper and thus far, only hums if the tube has issues.
I agree though, any hum in a amp, will be acceptable on the xover low sensitivity type speaker,,, , as its hardly noted,
but here with 97db, even the slighest hum, will be a aggravtaion.
