Raven Blackhawk LE... am I going to be disappointed?

So I have the Raven hooked up.  It was a preowned hnit and Im having issues with the sub out; it wont adjust the volume on the sub.  It passes the sub signal through the amp with the Raven off... strange.

Anyhow, its not warmed up yet and it actually sounds pretty dang good.  Plays stronger / louder than I expected.  It came with extra tubes too so I may roll some tubes later.  Fun stuff!

Raven will add the sub crossover to older units and since this one has sub out issues anyways...

I may just try returning it and swapping out for something else.  I got it at TMR and they have been really great so far so Im sure they’ll take care of me.  I want to keep my business with them on this so I’d try possibly trading for a different integrated.  The MF NuVista M3 looks interesting as does that Cayin tube integrated.  Problem is, coming off the Belles, its got to sound amazing number 1, then loud number 2.  This Raven is the firdt amp I put up against the Belles that can hold its own in terms of sound quality

I’ll update more here later today when I’ve listened some more

"...Sorry but BS alert. A watt is a watt unless the specs are juiced differently..."

Yes a watt is a watt. There is also "soft" clipping of the tube amp but that has nothing to do with the amps output if measured the same way. But what is different is that most tube amps have very good power supplies, decent transformers and large capacitors. My 25 watt tube mono blocks can hang with ANY 100wpc consumer grade receiver. Cheap under-speced components just don't get you to the same place regardless of the power specification. My little mono-blocks have 4 coke can sized capacitors, you wont see that in any mass consumer amp. So that's why we say there are watts and there are tube amp watts, even when we know a watt is a watt.    

So Im able to get an average of 90dbs with 95db peaks spl at my listening seat...

I am missing a bit of dynamics / slam that I had with Belles but the Raven is slightly more open and clear.  

We’ll see we’ll see

How long does it take to get a tube amp warm?  Its been 30 mins now, shes radiating some heat, and it sounds really damn good.  
I switched to 8 ohm tap... whats the difference between the two?  My speakers are nominal 6 and dip probably too 2 or 3 I assume.  
I started with the 4 ohm tap.  Can I use either?  Is it just going to be a difference in sound quality or does it put a bigger strain on the amp?

I am definitely seeing the appeal in a good tube amp though, whoa.  The openess, bloom and freq response is amazing.  I think its going to have enough power too which is really really surprising...

I'm seeing a lot of baloney here.  The amp designer, builder and marketer recomends speakers between 85 and 95 dB efficiency.
Take it up with him.
