The Puresound A30 integrated amplifier has been in continuous production for 13 years. This year sees its revision to the new A30-R standard
The basic architecture of a 30W amplifier based on push pull configured 6550 output pentodes biased into Class A remains unchanged. However, the single power transformer has been replaced by two separate transformers; one for the valve rectified and choke smoothed HT supply, the other for the filaments, “Overall this allows for cooler operation and a lower noise floor,” said the company.
The output transformer design has also been refined with improved lamination material and a different winding arrangement, “…yielding wider bandwidth,” said the company.
The A30-R features a motorised volume control and remote control with the option to mute via the handset.
The amplifier also now carries four pairs of line level inputs rather than the usual three. Switching between Ultra Linear had Triode operation has been retained, though.
The output transformers feature 4 and 8 Ohm taps to allow optimal matching with most loudspeakers. Price is £1899.95.

Hi Paul have you had any listening time with this yet?
I have a Rega Elex R running from a Bluesound Vault 2 into a pair of Heco Direkt speakers. How would the A30 R or even the A10 compare with the Rega Elex R?

Hi Ed – I have not done an ‘official’ A-B comparison with the Rega so my comments should be read with a measure of caution 🙂 That said, from casual listening in other people’s systems and so on I would see the A10 offering a mighty challenge to the Rega and would encourage a demo or request a home demo, if you’re interested. I would also expect the A30 R to be a superior creature to the Rega. As I say, though, take my opinions lightly. It also depends on your view of valves too, of course and their own special pros and cons.

Thanks Paul. Will you be doing an official review of the new A30-R?
Paul Rigby23rd March 2019 at 10:53 am
I hope to Ed, although I think the first item I’ll be looking at is a product that Puresound actually distributes rather than creates. From a Japanese outfit called Aurorasound.

Hi Paul, I hope you’re keeping well. Have you heard the new Puresound A30-R in action yet? I thought the previous A30 was pretty special when I listened to it – I’ve never heard a holographic soundstage like it. The A30-R is meant to be even better…..

Ooo, no. Sounds intriguing. I seem to have missed that thus far Ed. I’ll make a note. Oh, and I’m fine thanks, hope you’re ok to Ed.
