The future of preamps

You you didn't even bother to look before making ridiculous statements of this system quote:
"this is not really true, unless that source also has the ability to control the cable."
You put a White Paper out on this Atmasphere and you'll be shot down in flames. Mathematically how is the Nuforce not going to control the interconnects to the Belles?? You flat earthers are just too much!!!

Phusis sytstem:
Nuforce dac 9 has RCA Output impedance: 0.01 Ohm. It also has Output Voltage: RCA 2.0/4.0Vrms adjustable.

Belles SA30 30w Class A:Input impedance 100kohm. Input sensitivity .74v for full rated output.

hORNS Mummy MkII speakers: 94db sensitivity

Cheers George

this is starting to get ugly here!!! :( flame retardant suit required before entry.......

Nuforce dac 9 has RCA Output impedance: 0.01 Ohm.

I see that in the specs at their website, and in the manual. Surely it is a typo, though?

@ atmasphere, Hi, man-o-man did I enjoy your post about passive and active preamps, I actually learned something there, LOL!, not to sound arragant, that is rare for me, I love it!, also, thankyou for taking your time to explain how your preamp protects from DC, I am interested in your products to audition one of your preamps at this point, I do need to tell you thou, I have ridden myself a long time ago of useing preamps period, I have used solid state and recently tubed source direct to amp with success since 1996!, I seen you mentioned cable control, and a roll off of the top and bottom bands of the sound, presatation etc.., I addressed this kind of problem in my opinion, by useing some of the best cables money can buy to use with source direct to amp, the presatation is extremly focused and the presatation is very large and well conceived, the most transparent, with realism of an actual musical event that I can possibly afford to buy, In regards to your product, I am hopeing preamps have changed over the years for the better, I have listened to preamps this year, I do hear more information, it's all there!, I have never heard better transparency and dynamics, with realism than a source direct to amp, and God knows I have heard alot of cost no object preamps in my time!, I am also intrigued by your preamp for the simple fact it may not allow Dc into my amp, and your preamp is direct coupled like my amp is, I believe your design and circuit will give more transparency than alot of preamps out there, I do not know when I am going to listen to your product, I do know that I am going to, I have been enjoying this thread, you make it very interesting to be able to learn of circuits etc..., we need Almarg back on this thread too, cheers and merry x-mas to all of you!

@ Atmasphere, Hi, If your preamp M-1 is direct coupled, what do you use to safe guard from DC exsposure if I attempted to use your product with the krell 700cx?

I've only use tube preamps (Sonic Frontier, AI, CJ, VAC ...) with all my Krells amps (KSA100s, FPB300 and FPB600) in the past and never had a problem.

Don't like Krell pre and can't remember last time own a SS pre.
