Lol hmm the needs of the many out weigh the wants of the few, at least when it comes to audiophiles:).

No such thing as 'need' when it comes to audio. tongue.gif

Yes there is! At least that's what I tell myself to justify purchasing a LAu...

+1.  (or in this case, just 1 ha!)

couldn't agree more.

Thank you.


They had it paired with the Chord Hugo at Canjam.  It sounded absolutely fantastic.  That's the setup I heard it on and why I'm ready to buy tomorrow.

I hope there are enough Carbons for everyone who is interested!

Perhaps you should limit orders to one per person! :confused_face: 

 

Or at least one per order.  That way people who legitimately want more than one for more than one location can still get it, but they have to "wait in line" twice, giving others a chance.

Horray for design improvements?!

I thought the the same thing, and I'm still confused because of the following statements:

In case of the Carbon, it has a phase splitter at the SE input so that both halves of each channel are driven. This maintains the full power output in SE mode. Without the phase splitter, whether the balanced amp is truly differential or bridged, the power output does go down to 1/4 the balanced power.

 

We included the phase splitter so that those of you who couldn't or didn't want to get a balanced source right away could still have full power from the amp and would not be any more limited than others with the headphones you could drive.

Input: Standard XLR input (L,R) balanced. 3.5mm and RCA SE. SE is converted to balanced inside the amp. I don't believe you will hear much difference although I always prefer to go balanced in if possible.

 

Output: 4 Pin XLR and RSA (Kobiconn connector) balanced. 1/4" TRS SE. And remember that when you are using the SE out you are only using half of each amplifier on each channel. This reduces the power output.

 

There is almost no room left on the front for another jack. There might be room to squeeze a 3.5mm TRRS jack on the back, but it will be just barely if I can.

 

I have made RSA to XLR adaptors for using my Solo. It's a bit of a pain, but I would guess that a custom cable manuf would have these or could make them fairly easily.

 

I don't doubt the Carbon does actually put out as much power in SE mode as it does balanced, but could @runeight please clarify the above statements for us non-techies?

I don't agree with the limit per person. With the fickleness that has been displayed here (Head-Fi, Ala black schiit) it is not a good idea to limit the number of units one can buy. Alex priced this with the expectation and need to sell them all as I understand from talking with him.
post #159 of 5931

ok, how about "limit 1 per person during April 14,15,16 of the pre-order".

after that, additional quantities available to any/all.

 

this would at least prevent the rich guy ordering 50 Liquid Carbons tomorrow, and delay units from reaching Regular Joe ears in the early days of (eventual) shipping.

You mean someone like the Orpheus guy?  Here's the thing... if someone were being excessive like that, I would trust Dr. Cavalli to spot that when he reviews the orders.  I would also trust - by virtue of this amp being something he wanted to do for the community in the first place - that he'd do something to correct that (like extend the production run) should that occur.  In other words, it's a hypothetical situation, and I think that we should all jump off that bridge when we come to it, if we come to it.  :D

But do any of us really belong here? Because even though the musicians played the part in the studio for the purpose of getting it 'out there', did they really want us to be right there next to the microphone, listening to every note, feeling every emotion? Would they even look at you as they played, or would you disappear, never to contribute to the artwork that they created?

If some dude tries to do that, do we have permission to strangle them with oxygen free copper wires?

Lol, only if Litz.  We must maintain standards after all.

Each channel of a balanced amp has two amplifiers in it (so four actual amps for a two channel amp). The output is taken as the difference between the outputs of the two amps in one channel. This is using the balanced output.

 

However, when you plug into the SE jack, because the headphone wiring is taking the signal from the output to ground, you can only use one of the amps in each channel. This is what I meant by half of each amp. You are only using 1 of the 2 amps in the channel because your phone connector and headphone wiring are forcing you to do that. There can be exceptions to this, such as a transformer output where the grounding is not an issue.

 

When you use only one of the amps in the channel your maximum output voltage swing is no longer the difference between the two amps, but only the maximum swing that one amp can do. And since this maximum swing is, typically, half of the full balanced excursion, you only get 1/4 the power since power goes up as the square of the voltage.

 

The amp doesn't really have a mode. That is, with either balanced or SE input (with internal phase splitter) it is always running fully balanced. The only difference is where you take the output from.

 

If you use the balanced outs with balanced headphones you get the full performance of the amp. If you plug in to the SE TRS output you only use one amp in each channel and, while the output of the full channel stays the same, you are leaving 75% of it on the table, so to speak.

 

The other advantage to using the balanced output is that the noise will be lower because of what's called common mode rejection of the PS noise.

 

Let me know if this was useful.

Oh, I was writing while some of the order conversation was taking place.

 

We are not going to restrict orders per customer, but we are going to monitor what's happening and adjust if necessary.

 

I am very familiar with this problem. Trying to get tickets to a Rolling Stones concert many years ago. They did not limit tickets per person and so the first 50 people got all the tickets and the other 1000000000 people who had waited in line in the unbelievably hot Tucson summer sunshine walked away empty handed. I can tell you that those guys who immediately turned around to scalp those tickets as the rest of the people were dragging themselves away are lucky to be in one piece. :)
