Bingo!

And, beautiful set-up, Norbert! Thanks for the pic...

Hi Norbert,

Hy HP,

sorry that's not Eschersheimer Landstraße! Im living in good old Rödelheim. Actually the back-yard you can see on this photo is just the triangle between Alt-Rödelheim, Reichsburgstraße and Burgfriedenstraße.

Best regards,

Norbert

what is pretty good? 100+ or? have bought a interM REF-2300. is it possible to use my luxman as pre-amp for this?. also got a pair of fender speakers. gonna be intressting to see what it sound like! probably terrible huh? probably gonna sell those fenders. but the amp is lookin´ good!

According to my experience with various tube amps I would say that 8-10 is the minimum. A damping factor of around 10 is provided by most push-pull tube amps using a pair of KT88 or 6550 tetrodes like the McIntosh MC275 or Audio Research D76. Single ended triode amps using a single triode like 300B, 2A3 or AD1 often come with damping factors as low as 1-2. They are definitely out of scope driving the 2235 driver of a 4430.
I'm reaching deep into the area of personal taste but I think there is a limit at the other end too. I can't tell where this limt exactly is but amps like the Hafler 9505 (damping factor 1000) tend to withdraw some of the indispensable characteristics of the 4430 like liveliness and imaging. The top of the line Hafler is definitely not a bad amp but I would call the presentation flat and lifeless in comparison to a good tube amp or a transistor amp using an output trannie like the McIntosh 2100 (damping factor 14).

Best regards,

Norbert

Sorry Figge - was gigging this weekend and that kept me aways from the Forum (and unintended L100 bashing, but that surely saved me some $$ !! )

Do a Search for "Damping Factor", and you'll inevitably end-up at the dreaded "Amplifiers are more significant than you think" Thread: http://audioheritage.csdco.com/vbull...ing+factor+qsc The boys really got into it about damping factor (I even chimed in... ) with it's cross-links to other quasi-relevant Threads.

I don't know what the "right" number is. I know that the QSC's report ">500", and they produce very tight bass in both my home, and road PA gear (dual 18's, stereo). I would not advise using a tube amp for your lowrange. Many members here have similarly advised against that application. For the highs, fine...

ok... question about preamp...if i was to use the interM ref-2300 amp witch is a pro-amp. and my luxman l-430 can be used as pre amp. but i wonder would a basic 2 maybe 4 channel mixer (nothing expensive) do the work as pre amp better than the lux? cd player i use is a denon DN-2000F guess u can call it a pro player? vinyl player is a dual 505 mk2 with AT-95E. please dont give up on me cuz of all my stupid quesstions.
