the tough question: Which preamplifier? and why

as i understand, a preamp with a high output imedance, say over 600 ohms needs to see an amplifier's input impedance of around 50,000 ohms or more. the interconnect cable length and capacitance are also relevant.

That's what I thought lower output impedance for lower input but this one shocked me. I'm using MIT 350 ref 1 meter which has a higher capacitance I believe.

hi tvad:

you are wrong. my quartet of choices does not represent an opinion. it is just a list of preamps.

No. You are wrong.

Yours is not just a list of preamps. It is a subjective list of preamps as you state in your post. A subjective list is in itself an opinion of four preamps you preferred and selected.

hi tvad:

how can i prefer them when i haven't heard them. the list is an indication of the preamps i want to investigate. there is no preference for any of them. i may not like or purchase any of them. i am not recommending them or saying anything positive or negative about them. it is just a list.

there is nothing subjective about the list. they are 4 tube preamps. i could have added the conrad johnson et2, but i doubt i will be able to audition it.

the only subjective aspect is my intention to audition them. i hardly think an intention to audition a preamp is an opininion.

anybody care to chime in ?? if a person has an opinion about something which has yet to be experienced, it is a prejudice. are you suggesting i have a prejudice toward any of these preamps ?

Sure there is. There's clearly something about these preamps that caused you
to prefer them over 100 other possible preamps. Therefore, unless you put
all the possibilities on a roulette wheel and spun it four times resulting in a
random four picks...or, you placed all the possibilities on a wall, then
blindfolded yourself and had someone spin you around several times, and
then tossed four darts resulting in a random selection of four preamps, then
your subjective selection indicates you have a preference for the four
preamps on your list...for whatever reason. In other words, you have formed
an opinion regarding their suitability for your system goals.

We have to assume based on your posts that you are hoping for a warm,
caramel colored, rolled off presentation.

Good luck finding that.

I'm frightened by the possibility that you would continue this discussion until
each of us is in the Old Folks Home, and unaware of who or where we are.

So type away...but I'm done with this mini debate.
