Thanks for that info Brad. I am going to Modd the thing, I am now developing a plan of upgrade, but I want it to include a better source switch, volume control and better RCA's, or maybe a different type of connection for the IC's. With your cap upgrade did you notice a detail level increase?

Mr C

Thanks Brad. I will start with the caps. I stick to one thing at a time, to better gauge the improvement.

Mr C

Thanks for the heads up Brad. I have your pics saved already, I have been thinking this over for some time.

Mr C

Well, the DFR8's seem to be breaking in nicely already.  Everything is slowly getting smoother and less bright.  Even with using my new chip amp.  I still haven't gotten my TABOO back to try. I'll let y'all know when I do.  Maybe this is helping the breakin though. Sometimes when I go to work I'll leave a CD playing - cranking pretty loud.  I can do this with the chip amp and don't have to worry (it runs on 12 volts) like I do with my tube gear - plus it's more than twice as much watts.

Sure. Btw C, have you ever thought of adding a super-tweeter to your B200's?  I bet the Aurum Cantus G2Si ribbon tweeter I'm using would improve things for you quite a bit.

No.  But you have to cross it high enough to keep it from messing up the main driver.  If not you're liable to get peaks in lower treble and a potentially bright sound.

Besides the obvious benefits to drum cymbols and plucked instruments I noticed a big difference on bowed instruments, particularly cello.

I  had a  set  of the Russian Military  6N15Ns, and liked  them  so  much I bought a case of  50 @ $2.16/tube. [/quote]

You MUST send them in for a good Cryo treatment - it brings these tubes to a completely different level.  We did a group Cryo  buy/treatment a while back on these forums. Everyone really liked them including Steve.

Yes, I have.  There is less of a need for the tweeter with the DFR8's to my ears.  The ribbon still adds something, but with the DFR8's I don't miss the tweeter when not hooked up as much as I did with the FE206EM's.  It may have to do with the fact that the DFR8's don't seem to need felt around the phase plug to mellow out brightness the way the EM's did.  

The DRF8's (and my chip amp) are breaking in nicely.  The brightness initially heard is mellowing out.  Bass is still lacking - it could be it takes longer for the surround and spider to break in.  But again, can also be largely due to my "live" room.  More time will tell.

I  have  16 of  them  being  treated  as  we  speak  :)



Another interesting  thing  you  might  want to  try:  
Mount the  ribbon  facing the  rear, and  wire it out of  phase.

I'm  sure  this  'rear  ambience'  effect  would  work  better if  it  were  mounted  IN the  cabinet,  but  I  like the  effect  a lot.
