Default TUBEpre and Lightspeed LDR attenuator

Hi

I was looking at Broskies new SRPP preamp module

Broskie suggests it as a good partner fore SS amp with very low input impedance down to 1kohm

Lightspeed attenuator is very hot right now
And from the fact that Lightspeed doesnt need a buffer I thought maybe it will work in the unusual od place, after Broskies SRPP

Placed AFTER the tubestage the attenuation will also result in less noise, right ?

Any thoughts about the pros and cons, or anything else related ?

Tinitus, your CDP will drive the tubes nicely and the tubes will drive the Lightspeed nicely which will most likely have no trouble with your amp. Usually the suggestion is to have the Lightspeed as close to the amp as possible. I like those PIO caps. They sure sound nice.

Hi Uriah
O boy, no
I would use it fore my F5, fore which Im having heatsinks cut now, so still a long way
Same time next year

But the Broskie tube pre shouldnt take long, or cost much, so maybe it will be playing soon
Whether I need it or not, I just love tube preamps

Have you seen that cool case that AR2 got from Nelson? Looks easy to build. Okay, easy being relative to other cases, but not real expensive either. I am thinking I will try that. I love tubes to. The voltage scares the hell out of me though. The tubes sound better than any SS amp with my speakers and the Lightspeed but, man, I cant handle 300V!!
