Damn, that's sharp.

I'm getting mixed answers to whether or not I can run the headphone amp into active speakers. Can anyone else chime in on this? 

 

[Doc B.]

What is the reason you are being given that you can't do it, and by whom? The speaker manufacturer?

 

[Nic Rhodes]

It is fine, active monitors are a great solution.

The GEC 6as7g curved bases arrived today, they look brand new and more importantly they sound very nice indeed!

Nice, Please post some comparisons with TS 5998 (I assume you have one).

THe GEC synergy with HD 800 is

. Was listening to HD 800 with the GEC + TS 6SN7 combo on the Crack last night, time flew & before I realised it was 2 pm & I got only 5 hours of sleep. Feeling so F@#%*d at work right now. Damm this hobby

 
Listening to them right now, same story , different day

 grrr great tubes

Sorry nic you will be pleased to know I am all done buying tubes for the time being. Somehow I ended up buying three GEC's this week! As well as the pair I put a low offer in on one that had just been listed and much to my surprise it was accepted and even came with a 28 day guarantee! 
 
Did you get the GEC quad?

I do which type single or dual getter 

 
I need a bit more time with it first. Its very similar to the straight base but seems a touch more refined in the details, its hard to put a finger on at the moment. Safe to say its very much a grin inducing & toe tapping listen.

I would suggest that "someone else may know why it won't work" and "don't turn it up too loud" are not particularly lucid technical arguments. Yes, the Crack can put out a reasonably high level into a high impedance load. So can a lot of preamps. I have confidence that you can use some judgement with respect to levels. The comment about impedance makes no sense. The low output impedance of the Crack - relative to its use at line level - is a plus. The Crack was actually used as the starting point for a series of experiments in transformerless low impedance tube preamps that led to the development of our 300B preamp. But go with what you feel is the best answer for you.

Thanks, I'm definitely going to trust the person that designed this amp! I'm going to be dealing with 3 volumes here. The active monitors, my computer, and the crack. How should I go about adjusting these? I know for sure I don't want to be cranking up the crack!
 
Edit: Oh yeah, a subwoofer is also fine right? 
 
Excuse my basic questions...
 
What are the do's and don'ts of a tube amp?
When the amp is unused, turn it off..
Plug in the output device after 10 seconds warm up?
Unplug before turning off?
Turn the volume all the way down, then turn off?

Do you need the Crack in the chain? If you have volume controls elsewhere I'd question whether the Crack is bringing significant benefit (unless of course you're looking to add tubey goodness)

For tubiness, I found that the Quickie was a far better choice as a preamp, but you do need at least 20K ohms input impedance on your built-in amp, 40K if using PJCCS upgrade.

I'm looking to add tubey goodness to my active speakers! I don't use them for any recording so yeah.

If Doc B says it's ok, give it a try for crying out loud! B-)
