hi there my name is Alex Cavalli I make high-end headphone amps from my company Cavalli audio my first headphone amp was liquid fire liquid fire is what I call an embedded hybrid headphone amp that means the tubes and the solid-state components are all blended together in a single DC coupled amp the liquid fire has powered since its introduction probably a hundred sets of headphones the next of my amplifiers is a liquid lightning which is a solid-state electrostatic headphone amp you can see it right there with stacks SR low nines and the third and newest product from Cavalli audio is called liquid glass a liquid glass and liquid hybrid and liquid fire are both hybrid headphone amplifiers but they're very different the liquid fire is a circuit where the tubes in solid state are blended together and it's not really designed for two rolling it's designed to emphasize the quality of one particular type of tube whereas the liquid glass handles or rather can roll probably over a hundred different tube types so unlike other amps where you can roll two of the tubes of the same type but different vintages and different manufacturers the liquid glass will allow you to roll many different tube types so on the table here we have 6s and 7s and 12 au 7s and 6g u 7s and bt 180 ones and at least a hundred different types of tubes can go in this amp it's self adjusts and the interesting thing about it is that the output buffer is transparent to the sound of the tube so whatever tube you put in there whatever it sounds like is what the sound is that comes out the back end of the amp so it's a really cool lamp for somebody that has lots of tubes and wants to do some - rolling I think it's the only one of its kind on the market today so this is my stuff and I hope you all will think about it you sure I just want to sure so we'll just step through it I'll just turn it off and you can see that there are octal tubes in there now you can just probably see barely behind that there are no vol sockets but if I pull one of these out it's going to be a little toasty you can see the no vol sockets in the back so if I want to change to a 9-pin tube I just pop them in make sure that the heater voltage is set right which in this case I know it's already correct for this tube and you also may notice that there's kind of a physical interlock so that if you put either one of these tubes in one channel you can't put the other one in because they simply physically block each other so you can't make the mistake of putting two tubes in one channel so here it is we'll just fire it up and it'll come right up it has the classic Cavalli audio heater warmup delay time so you'll see it it won't apply the the high voltages to the tubes until the heaters are warmed up and then has an offset delay detection system so it waits until all the DC at the output settles before it connects the headphones and it's just about through its cycle and in another 15 seconds it'll be ready to go thank you
