Ok, I guess it's time to write out our experience with the Dentons.
Speakers: Wharfedale Denton 80th & Jamo Concert 8
Amplifier: Cambridge Audio Azur 840a
Interconnects: Bogdan audio low capacitance silver coated OFC with Eichmann bullets for the concert 8 and Lyrita + a german make silver IC for the Dentons
Sources: CA 640c and Xonar STX
Speaker Cables: THX Monster collaborative OFC for Jamos and Jamo OFC 20 gauge for Dentons
Objective: To assess Denton's performance on Cambridge Audio Azur 840a
Observations:
When I first saw the dentons, the first thing I noticed was the thickness of the rubber ring around the woofer, it was indicative of a high excursion driver. This automatically told me it would have an interesting kick to it's lower midrange. Once hooked up, I was not surprised. They had the same kick to it's sound as the Jamo E700 bookshelves I once had which also had high excursion woofers, pictured below:
I would not call the Denton's warm, but I would call them..soft with a kick.
It's a relaxing laid back type of sound which performs everything it's thrown at in a not too warm but warm enough to make them listenable many hours. However with that softness, is lost some defining qualities of many genres of music. 'Texture' for example is audible as texture but it's not totally transparent.. in the sense of being able to make out the "type" of texture. If that confused you, read the sentence again because the difference is subtle but it can make or break a speaker for many genres.
On that note I would not suggest the Dentons for electronic or house or lounge or large orchestral music. I would suggest it for Piano, Guitar, Harp and solo vocal music. Jazz for example is quite nice on the Dentons, songs like "hotel california".... but not electronic music like the Blade Runner Soundtrack where detail and textures all have their own individual types.
The Denton + CA840a combo is nowhere near as warm as the ca 840a + b&w cm9 and paradigm monitor 9 or Avidyarthy's ATL's made by Hari Iyer combos, which is a good thing. The Jamo concert 8 when compared against the Dentons lack that high excursion kick to the sound...but the price difference of 2000 USD is very audible in every other aspect of the Jamo's sound. Which is why I am not writing much about "Denton VS Concert 8" but more "Denton & Concert 8" as a reference point.
In regards to soundstage the Dentons are like a Jack in the box, they're a small to medium sized bookshelf speaker but have a soundstage as wide as the Jamo concert 8 and Hari Iyers ATL's. My previous floorstander Jamo e875 had a much narrower soundstage compared to all the three above.
Now regarding the 840a's ability to drive the Dentons, I think it's a matter of preference. They have no issue driving the denton's. Details are present, midrange is nice and thick, transparency is at par with Hari Iyer/Avidyarthy's ATL's, midrange is fun, absolute low end bass is not there as is with all medium sized bookshelf speakers. Note ABSOLUTE low, not saying it has no bass. But the question that determines if an 840a is suitable as an amplifier for the Dentons or not lies in the question if the listener prefers the ca840a's "soft" sound signature which is typical of British sound, or would one want more sparkle in their music, in which case I would point at a marantz or a denon class AB amplifier.The CA840a - which is better for taming bright speakers in this case is closer matched with the Jamo concert 8's given the CA840a's non bright sound signature.
For example when we did zone A(concert 8) to zone B(Denton) one could automatically notice there was an airy sparkle and residual tonality in the concert 8's which was missing in the Dentons, by missing I mean not present at all, not even with ones ears at the drivers level. Granted the Dentons are USD 800 vs the Concert 8s which were almost USD 3000 but my point is perhaps pairing these Dentons to a slightly brighter amplifier
might allow it to produce that little extra sparkle if the listener wants it.
I think that covers most of the important parts. Any questions feel free to write below.
. I have heard very expensive setups and I observed that with might and power it takes away the sweetness and emotions rendered in the music. The B&W are top of the line BMWs.
