The preamplifier AVM PA 8 can be expanded with add-on modules. As a partner, he is the power amplifier SA 8 to the side. We have tested the combination.

How come the best amplifier actually? With much knowledge of engineering or rather feeling and experience? Or all together? Tap on the former could at Gunther Mania by the Malscher company of AVM. Finally, the Baden in Karlsruhe has studied officially amplifier construction. At first glance, his latest creation, the precursor of PA 8 from the Ovation Series (which is the operator with a nice TFT graphics) promptly looks like polished art of engineering.

AVM PA 8: Extensible precursor

It feels like. The chrome-plated metal heads have haarscharf exactly the right balance of mass, so that they rotate with exactly the correct Schwupp in the precision ball bearings. Small mistake in turn allows menus to navigate – only in a few, as for the purpose of sound shaping. Soon maybe in many, due to the PA 8 thus we practically to their crucial advantage – with various acquisition plug-in boards at will can be expanded. And because these modules an own software with “Hello, we’re there too!” according to the motto, with the 8 then makes sense can take the PA including display graphics in the game.

The base version of bring – which they installed a – output amplifier with WBT RCA and balanced XLR Kontakters. Moreover, a switch for permanent-an and-Aus and a Jack, which allows the trigger group in case of need. For the cost of 6450 euros, AVM also bought a card with digital coaxial and another with XLR inputs. Phono MM/MC, digital/analog, USB and DAB/FM tuner are the other currently in Malsch still maturing rack expansion options for 1250 euros each. Already longer in series and integrated already in the test patterns: a de luxe output Board for 1990 euros, who works at apparently sound decisive point with Dual triode tubes and then but greatly transcends the Normal University and engineering.

AVM PA 8: Construction

If any tube, then before the conventionally educated Elektronikus the effects poor and relatively immune to complex load vacuum piston in the final output stage. Far from it: The PA 8 creates in this place (like many other precursors also) with powerful Push-pull semiconductors. And: Gunther Mania ECC 83 ordered significantly further ahead before the volume control. But before a muses 72320, a new IC, which brings a sensational Dynamics of a minimum noise reason to ends of 12 volt – its manufacturer of new Japan radio calls him proudly “Mystic Jewel of Sound”. By Mania controls the JRCs with the joyful high-voltage triode, he attempted further to grind the jewels. In addition, he drives the tubes themselves about their base point cathode and gets so – the grids are connected to ground and work towards as a shield – a very excellent protection against unpleasant side effects.

That didn’t prevent the master but not by further icing on the cake. Like he uses two channels each of Muses-IC for a balanced circuit design and a further increase in Dynamics. And he can be the high-level and only buffered and balanced inputs on extra wide and run thick as well as gold-plated Kupfertrassen – instead of an ordinary bus could be here so more talk of a kind of Turbo-fast formula 1 System.

Through appropriate paths, the PA 8 proposes to also supplying course as highly pure DC current, which after then will again thoroughly cleaned each plug-in Board. Remain still danger that a normal transformer magnetic means sauigelt. Therefore, AVM relies on an switching power supply of end far above the audible range of clock. There is an exception only for the tubes: your best shielded extra voltage converters is fed on the inlet side with specially generated 300 hertz frequencies – but need to know, because they are neither measurable nor heard.

AVM SA 8: power amplifier

Who relies on the WBT-RCA tipped tube module for AVM prepress, will not ask according to the connection of stereo power amplifier SA 8 and uses, for example, a solid coaxial with Teflon insulation.

Input buffering, push-pull voltage gain in principle continues then’s when the AVM like at other power pins also. Actually already ordinary 2 x 30 watts came out out by powerful toroidal transformers the Fed power levels. But the AVM sets – from the eco-savings operation – then so right go. He takes here rather this performance to turn the relatively large input capacity of not less than 2 x 24 thick field effect transistors from the home international rectifier without contradiction. The semiconductor packs (whose guided electrodes and current channels are not directly connected, but some sort of capacitor form) it thanked with a great impulse speed. And with enormous power power. Each amplifier has its own giant-kilowatt transformer and not less than 20 Memory cellos (Roder gem with each 10,000 micro Farad). Not the SA 8 stand also short-circuits – protection circuit then waits quietly still a few seconds until it but rather “cease fire” orders.

AVM PA 8 + SA 8: hearing test

Playing the piano, the power amplifier SA 8 proved his mastery. The AVM left not only by the seemingly important snippet grab the microphone, he was rather noticeably the entire wing in the listening room and gave the required reason thus the most powerful chords. Also at major orchestras, the SA 8 knew no limit: the double bass players want angry and the violins flare up as they wanted: it was always clear that this amp can breathe more freely and has reserves to the arbitrary expansion of space. When it comes to probater control, the preamplifier PA 8 was generosity, space and depth. This was also true of the normal only-semiconductor output, the tube module offered even more flow and more heat. A hint came more neutrality when musicality – thus the PA 8 AVM final 130 points and the precursors Elysium.
