Just received one of the first Quad VA-One valve amplifier.

Here it is and will open it up later.

One valve output?

15 wpc into 6 ohms, says the spec.

More info and pics tomorrow, when I find time to grapple with the camera and struggle with 'dial up' internet speed.

The Quad 303 was so called because it could produce an output of 30V at 3A, i.e. 90VA or 45watts/channel.

Was the 405 - 40 volts at 5A ?

No idea why the VA-One is titled that. It's not their first valve amp. Maybe it's the first in a new range ?

Still struggling with technology. The camera shows a red screen and locks up ? I'll try again later.

Well I like to think so. The power supply rails were +/-50V and the fuses were 4A, but I think the actual maximum output at the speaker terminals is 40V at 2.5A for each channel.

It certainly would fit in with the "4" of the 405 as denoting the Series 4 range of Quad electronics. This linkage would fail with the Series 5 and later series of Quad electronics.

It's good when the name or numbering actually refers to something. So, not quite the case with the 405 and later models.

How are you finding the sound, Dave?

It's really good and goes far louder than it has any right to go. Using the Harbeth SHL5+, it goes plenty loud enough for me.

The VA-One has an inbuilt DAC, which I will be trying later and a headphone amp, which sounds excellent. You could pay the 1300 Quid for a headphone amp alone of this quality.

I just love the Quad industrial design. Clean looking little amp. Does it feel like a Quad (weight wise) ?

Not that it does anything for the sound but it's a lot heavier than I thought just by looking at it. A whole lot of iron in the x'mers I suppose.

Yes, the design is nice and clean and harks back to Quad of the past, especially the volume control.

I must get around to posting the specs and a couple more pics..:doh:

It has one line input and various digital inputs. The DAC is extremely good and well worth the asking price of the amp on it's own. Like buying a DAC and getting a free amp.
Just had a rave write up by Ken Kessler in the latest Hi-Fi News.

Oh and it does Bluetooth.
