the tough question: Which preamplifier? and why

hi tvad:

you are wrong. my quartet of choices does not represent an opinion. it is just a list of preamps. check your definitions of words. there is a difference between facts and opinions.

my 4 selections are not opinions they are statements of the existence of these products. if i say "mcintosh", is that an opinion ? i think not.

the more obvious is my statement "don't rely on opinions", which is an opinion. i'm surprised you did not acknowledge the paradox.

one's ears as has been said many times, are more useful than second-hand opinions.

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:

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 ?
