Best B-150 Power Amplifier

This test goes to a perky integrated from Denmark. The best B-150 (4100 euros) dispenses with big knobs and any posturing. Connoisseurs know: the intelligence behind the front.

  2. Data sheet

He is kind of a Crown Prince of Denmark: the best B-150 Fourkopfi belongs to a – gen integrated amplifier lineup, which has approached AUDIO from the cheap end: in issue 3/06 the “small”, identical in dimensions, but lighter and weaker B-110 as slim, but inaugural fast 1500-euro sports gun recommended.

The B-150 should be able for 4100 euro Gage then not only the Sprint, but also the shot put. Why, Thomas Sillesen, Chef and thinker of Densen, his second largest amp first prescribed the most powerful toroidal transformer, which was still in the flat housing. A new wrapping technique to prevent this three-quarter kilowatt Brummer from becoming the electromechanical troublemaker: while Mr Lothar Brandt had to record yet “transformer hum” as a negative point in the test of the B-110, the alternator was in the B-150 exemplary vibration.

The power amplifier of the Densen bipolarer employs two couples, very broadband ring-emitter transistors (fell 2SA1216 and their complementary brothers 2922), which have to make do without any feedback. Sillesen avoids this control measure, despite favourable effect on almost all traditional readings, because his opinion is detrimental to the sound.

Without the feedback control loops ever get to a stable, suitable for HiFi amplifier, Densen must build it, from the outset as clean and poor tolerance as possible. That alone can explain the almost clinical cleanliness and accuracy, which exists on the B-150-Board, but only to the extent. The Board itself is expensive, unbeatable low-loss Teflon, equipped it is mostly just in the SMD process, namely to two hundredths of a millimetre. The solder joints arise under nitrogen protective atmosphere with silver solder, all resistors are from the noble manufacturer Vishay, the they laser on tiny 0.1 per cent tolerance trims. Quite conceivable that that a B-150 not only immediately after purchasing sounds good, but even in ten years.

Then, half of the warranty has just expired for the original purchaser. Densen would stand even for life for his amps – a promise that a truncates the German distributor for competition reasons for 20 years. Wear and tear parts such as potentiometers, which are however not in the B-150 are excluded. Not the ubiquitous PGA anyway chip by Burr-Brown, but a Bank of discrete relay processor-controlled 200 exact values combining a squad of said Vishay resistors serves as Poti replacement. A more precise volume can hardly imagine basically – the vivid clickers of the signal box at level changes is getting it at most.

In terms of equipment is best for eh and depending on upgrades options. So he offers for example several Phonoplatinen for lovers of vinyl listening. Also entice the Danes with other, more exotic features that are useful only with the purchase of additional power amplifiers: A multichannel Board makes the B-150 to the surround amp, custom made active crossover boards (SAXO, 600 euro per way) allow the subsequent activation of existing speakers.

The Danes have forgotten only a headphone jack. This does not apply to the remote control, but a surcharge is for the external control devices actually. The system remote control “Gizmo”, that can control the whole Densen appliance Park, proposes at least with 260 euros.

The listening session with the KEF reference 207/2, since the test in AUDIO 9/07 always drawn up monitor for all strengths and weaknesses of any electronics, led by a large number of CDs and SACDs as well as several high-bit files, reproduced by the Linn Akurate DS.

Precise and defined

Tom Brosseau it began: the tester still good from the 1500 euro amps in the ear hearing test had its unimpressive opener “Favorite Colour Blue”, but the piece was now almost unrecognizable: here each note had its well-defined place to stay, which he retained until the last swinging out. the first, sparse notes bargen more surprises as many sound technical feat via a mittelprächtigen compromise amplifier.

As well as also cinema films are just not grain-free, all the plates have a Feinststruktur – here of somewhat grainy Emery in the piano, as a light tremor in his voice, there a low onset analog tape. And these subtleties, these imperfections that can subconsciously create tension–they seemed to be interested in the B-150. That was not always nice, a monitor-like proximity to the recording generated but, an effortless with ver consequences can really each track, each swinging, each string skidding.

Dynamic and agile

And certainly not always, there were only edges that emerged over the best: the ultra tight-recorded instrumental rock masterpieces by Cougar (“Patriot”, rough trade) burst so dynamically and with so perfect timing in the listening room, that was scrawled on the memo pad of the author after only “like live!”.

Classical music fans, especially opera fans, will record that perhaps less frequently. Of course offered the best B-150 also Tenors, Sopranos, and other trained vocalist a magnificent stage, but the velvety, sometimes bitterness shades as they ranking (and more than twice as expensive) amplifier like an Accuphase E-560 (test in AUDIO 4/2010) in addition to all power and glory can conjure, the Dane embezzled a little. Maybe his Developer also didn’t want to this flattering, cosy element. Because he is approaching the ideal just from the other side.

In the famous drama the Prince “Hamlet” can recite Shakespeare his hero the famous saying: “There is something rotten in the State of Denmark”. The bottom line, Thomas Sillesen has an impressive proof beaten that Danish Crown Prince over a wonderfully fresh-sounding realm of tones and nuances can areas. Without that there in the least lazy thing.


Who needs even a volume knob, if he wants to actually stand up, but listen nonstop? Maybe even the remote is dispensable: the Danish top amplifier Dynamics makes an experience, because he is agile and honestly how few things and the word seems to know aim simply is not.
