Available in the shops now anyone had a demo? Looking to use with Dynaudio x 12.

Not that Arcam is available in my market any more, but still very interested to hear about this amp, including how it pairs up withthe rDac, etc. seeing as it has the ability to power Arcam's own rDevices.

Got one yesterday on sale from Audio T for £585. Needed a amp for a turntable and for use with headphones (previous all in one had too much buzzy interference and wouldnt have ran a turntable). I cant really comment performance wise as its my first amp but im happy with it. Oh yeah, I use it with spotify/Itunes through a rdac so the accesory power thing is pretty handy.
Thats a good price as well so you have got a good deal. Post an uipdate if you get a chance and let us know waht you think?
If it's like older Arcams, they don't have the purest current ...
Pretty ... and pretty proud of it
I don't do technical. The older Arcams can struggle with hard load speakers, such as ATC, Dyns, Spendor... one reason why I generally recommend MA, Focals, PMCs etc. If they are going with speakers like Dyns I'd recommend using a power amp to give it a little oomph.

Understand and no problem PP. Arcams usually measure well within their given envelope. They are both cautiously under rated and have low output impedance making them a relatively good choice for a variety of speakers. Perhaps the power supplies are a tad small for their actuall ratings which could explain your and other users impressions. Similar in a way to the Roksans. The K2 is rated more powerful than the Caspian but doesn't sound it. It's how the power is derived if that makes sense.
To elaborate a little on this (and to bore everyone to death) ... I believe it is generally assumed that the VA rating of an amplifier transformer should be around factor x 2.5 of that of its w/rms rating. That is about the minimum for adequate electrical supply. There is no upper limit on transformer size but the law of diminishing returns applies with increase. Some manufacturers of products in the higher echelons of hifi are probably vastly over specifying, in some cases probably to explain the huge costs (and to add weight) ... both somewhat related in hifi. - As to reservoir capacitance, there is still no consensus on how much exactly is needed but I once read an interesting technical argument that around 4400uf per channel for a 100w amplifier is adequate. Perhaps and there is definitively a place for low power, low component value amplifiers. Users have repeatedly commented on the increased 'musicality' of such designs. Having said that, there are no doubt many arguments for good, solid power supplies. - Naim, amongst others, have realized that a long time ago. Their designs usually being cautiously rated but having decent supplies which in many cases can be further increased. You may have different ideas on that. There are two opposing camps, one is that multiple, small caps are a better solution, for reasons of quick re/discharging, lower esl/esr values (Creek amongst others being one), the other side arguing that it matters little and the same can be achieved with larger/fewer caps. Manufacturers adopt both theories, with varying degrees of success if reviews are to be believed so there is probably not one correct solution and, ulitmately, design of pcb and all the other parameters of amplifier designs are important too.
When buying a budget amplifier, you usually can expect design parameters to be around the minimum requirements for quoted performance. Smallish transformers and just about enough supply down stream. More money will usually (but not always) buy more elaborate and higher component quality (and packaging) as well as more power, though that on its own is no guarantee for top sound either.
I dont understand all the ins and outs of amplifier design so the above is just a very simple outline. It can get very complex once digging into the details of details. This may also explain some of the cost of designs which may at first seem high. It furthermore highlights the enormous value for money people get these days with for example AV products. Economy of scale playing a huge part.
I didnt say they were made in Britian I said they are British companies. Most economies out source not sure what the problem is to be honest. They all employ people in the UK as well and make great products.
B&W moved production to China and their speakers don't sound half as good as they used to. Just saying.

just a quick update. The A19 is in the building and it's currently being reviewed - we'll have a full, exclusive review in the Feb issue of the magazine...
Reviews Editor, What Hi-Fi? Sound and Vision & whathifi.com
Thanks for that explanation drummerman. Interesting.
Pleasure. For anyone interested in more than headlines, head over to DIY Audio.
Whilst a lot of it will go over many peoples heads, it is one of the better places to learn. There are very good minds there, debating all things hifi in a mostly objective way, backed up by technical reasoning/measurements. Quite a few of the contributors are electronics engineers and some of the creations have/will end up in commercially available designs.
If it makes anyone feel better, even they often can't agree on which way is best but it all adds to the diversity of this hobby of ours. Furthermore, most of them seem to live in cellars without windows and which look like a bomb just exploded.
Well the wait is over and the Arcam has had a very positive review in this months edition of WHF. What did people make of the review? Clear improvement over the previous model it seems.
Small snippets on the second page of the review are interesting when they start to compare the 19 with Cyrus and Rega models. 'The Arcam's scale is unmatched the soundfield is larger and more open........... '
I heard it paired with its matching cd (don't know which) driving some cm1's and it sounded very good. I bought the cm1 to pair with my alpha 10 and it was horrible and they had to go back. In the end I kept my rs6's, ditched the alpha and bought a brio r and WOW
Anyway, I think I can honestly say the new arcam gear ain't nothing like the old stuff.
hmmm...I wonder which would be better - an old Alpha 10, an A85 or the A19 ?
