In the Thread: A listening room for a domesticated Cat?
Post Subject: I need some volume…Posted by Romy the Cat on: 10/28/2017
This morning we all:
Amy, kids, nanny, cats were watching Schleswig-Holstein
festival from 2000 where Gunter Wand was leading his North German Radio Symphony Orchestra
with Bruckner 8. The kind were playing
with my laser rangemeter, women were drinking coffee and eating halva, cats
were searching a new spot to pee and I was thinking that with some quite recordings
when I have a good brass crescendos I need more volume. The spectra composition
of Macondo now is very fine but for the size of the room I have I need more
gain.
Well, gains is tricky subject. If I want to stay in class A then
I have a very limited power reserve, I would estimate that I have 3-4dB left
before I got to A2. So, considering that some records are very soft I think if
I have 6dB more gains it would be great. I should not even need to worry about flooding
of the input stage of my power amp: the 6E5P has 4.5V bias…
So, I was thinking about some kind of active gain stage that
I would put in the tape loop of my Placette preamp. Alternative would be
another active preamp but I downs that I will find anything as transparent out
there and anything that have out impedance of few ohms. I spoke with Guy Placette
and he told me that he has a devise that has 6dB gain that I can use after his
preamp and that devise has 8R output impedance. I did not try it yet but frankly
I would like do not daisy chain the buffers. So, I am wondering…
