Spatial Audio Raven Preamp
For anyone interested who perhaps has a Raven already...  Spatial has one last pair of the original pre-production Blackbird amps that they are going to sell at a discount.  David will post them on his site shortly.  If you are interested you can ... 
300B Tube Amps with 15/16 Watts Per Channel?
@vthokie83 Just curious.  What speakers is your friend driving with the Blackbird 300b amps?  Just another data point!  
300B Tube Amps with 15/16 Watts Per Channel?
@vthokie83 Interesting.  If you do get the chance then please post your impressions!  
300B Tube Amps with 15/16 Watts Per Channel?
@vthokie83 Yes, the Blackbirds measure out at about 24 wpc. I know Aric and he builds seriously good tube gear. He is a master craftsman. That said, I wish you could hear the Blackbirds with the matching Raven preamp:) It would be a different exp... 
300B Tube Amps with 15/16 Watts Per Channel?
@dietrdeb  I wasn't really suggesting you buy the Blackbirds, just that if you do the 300b route I really think PP is best IMHO.  My system is fully balanced from Pacific 2 through to the amp speaker terminals.  It is so quiet that I cannot even ... 
300B Tube Amps with 15/16 Watts Per Channel?
@debjit_g  There is an old customer of mine who has a prototype pair of the design used for the Blackbird amps that Spatial audio is producing.  PP300b and they produce about 24 watts/ch.   He has one of the Cube speakers as I recall and the amps ...

@rav6258  Yes, it is 64 step attenuator, and the first step is 00.  It should be screamingly loud by 50, and most listening levels should fall in the 25-55 range on most systems.  Is that not the case in your system?  63 would blow the speakers o...

To follow up on what Lynn just posted.  I spent my time rebuilding vintage tube gear with modern parts, then I decided to make my own and always tried to make it reasonably affordable and be better than the vintage gear.  The Raven and Blackbirds ...

@rav6258 I looked at the Bottlehead kit and indeed it is a steal for what the price was.  I expect that it sounded very good.  They cut corners for the price point, but made some very clever choices.  Just looking at the kit photo I would expect t...

@pindac Sadly, it appears that wire is out of stock.....  Might be a fun experiment if some were available

@phono2024  I stopped shipping cords with my builds as people always tossed the cheapo one and used something better, and I was tired of the waste.  I suspect Spatial has the same policy, so you probably should enquire.  I know Lampizator doesn't... 
Spatial Audio Raven Preamp
@phono2024  sure, I am biased because I designed them, but in my system with 95 dB speakers, the Raven and Blackbird combo is dead silent idling away.  I can put my ear to any of the drivers on the speaker and barely tell the system is on.  Hiss...

@jc4659 So glad the anticables worked out for you.  Same setup I am running, with xlr from my Lampi Pacific 2 to the Raven and xlr to the Blackbirds from the Raven.  I am going to get Paul to make me speaker cables eventually when I get around to ...

Hi The Raven gain is about 13.9 dB (5X voltage gain).  The RCA and XLR inputs have the same gain.  The Khozmo volume control has a very nice log taper and you should have good adjustability in most systems.  Not touchy.      I would run XLR fro...

Imagine high speed levitating electric trains down the insterstate medians..... They would be far more efficient than planes for the 500 mile or less journey.  They have trains that go 199 mph in Japan.  Imagine just 120 mph.....  a few hours and ...
