Writer’s ability to learn
The distance between letters, free handwriting analysis, refers to the interaction between an individual and emotional environment. Refers to different emotional feelings and reactions and its ability or inability to express these feelings spontaneously and appropriately.
He refers to his generosity in relationships, understanding the emotional needs of others. The distance also gives the holder of the author of reactions to others’ ideas, behaviors, practices, emotional reactions in general and a certain influence on the writer’s ability to learn.
Accuphase M-6000
The M-6000 was born out of a thorough re-evaluation of the power amplifier from a new vantage point. Aiming for nothing less than the ultimate in sound quality, this monophonic power amplifier with its massive heat sinks on both sides stands as an impressive achievement. The decisive difference to conventional designs lies in the fact that the M-6000 possesses two completely identical power amplifier circuits which are driven in parallel. Kept entirely separate and mounted on the left and right sides of the chassis, these circuits deliver output current reserves on a previously almost unheard-of level. A damping factor rating of more than 500 demonstrates that this amplifier is capable of driving even the most difficult, ultra-low impedance loads with ease.
Nothing was left to chance: the mono blocks M-6000 are going to set a new
benchmark in the portfolio of Accuphase. And they’ve got the making to
bewitch even the most discriminating listeners. Well, the virtues of these Japanese power plants simply cannot be debated
even by down-to-earth contemporaries: their stability under any condition guarantees
that even with critical, demanding speaker systems the sonic results are not spoiled
by interactions between amp and speakers. The overwhelming output power will
bring also low-efficiency transducers out of their shell. Month by month the newest hifi appliances are introducing themselves in the AUDIO listening room and hence for comparison purposes a power amplifier, which is stable under any conditions, is
worth its weight in gold.
Talking about value – this seems to be the biggest difference between a pair of
M-8000 and M-6000, whereby the latter, with nearly the same promising power,
comes with a price tag which is about 35% less expensive than the one of its bigger
brothers. No question, this is still a lot of money for two monophonic power amps, yet,
like with any other audio component from Accuphase, when put into perspective as to
the stable value over the time and outstanding workmanship, one might think a bit
different here.
Inside, we are to encounter some big changes indeed. Instead of bipolar
transistors there are field-effect semi-conductors, a.k.a. MOSFETs, taking care of the
final amplification. While conventional solid-state devices of the bipolar variety are
trying to amplify low base currents, the work of MOSFETs can be compared with a
tunnel for electrons of which width and thus flow rate is regulated by an electric field.
Rather, the function principles are reminding us of those going on in a thermionic
valve, and this is also why many high-enders believe the sound of MOSFETs coming
close to the sound of valves. Instead of employing a pure Class-A circuitry, in which the power transistors
are permanently wasting half of the maximum output power in form of heat,
Accuphase has gone for a push-pull circuitry in A/B mode of operation in the two big
mono blocks. An array of 16 MOSFETs amplifies the signals below the cross-over
line while the other batch of 16 devices is doing the same above the line.
If you are looking to purhase one of these yourself, here’s an idea:

Esoteric MG-20
The Esoteric MG-20 is a slim, elegant tower almost 42″ tall, and the front baffle of its trapezoidal cabinet is slightly wider than the rear. That front baffle is 30mm thick, and the rest of the cabinet is constructed from 15mm-thick birch ply, veneered on all surfaces (including internally) with American cherrywood. Solid American cherry is also used for the side rails flanking the baffle; in combination with the extensive internal bracing, this gives the speaker cabinet an inert feel. The enclosure is filled with long-hair wool, but, peculiarly, the lower third of the enclosure seems to be sealed off from the chamber that loads the woofers. Under the lower woofer is a flared, spirally grooved port 1.5″ in diameter and 3.5″ deep. Though the port tube is made of plastic, its outer surface is damped and reinforced with foam rubber.
The stars of the show, of course, are the magnesium-diaphragm drive-units. Two 6.5″ woofers are used, one above and one below a 1″ tweeter. The woofer is constructed on a diecast frame, its magnesium cone terminated with a substantial half-roll rubber surround. Pressed into the cone is a concentric ring to control its breakup behavior, and the dustcap is also made of magnesium. Special attention has been paid to linearizing the magnetic drive system. The tweeter also has a small half-roll surround, and uses a neodymium magnet and an aluminum voice-coil. The dome is slightly recessed into the shallow, flared front plate, and the rear of the diaphragm is loaded with a damped rear chamber. All three drive-units are rabbeted into the baffle and secured with Torx-head screws.
The MG-20′s hardwired crossover comprises two inductors (one air-cored, the other with a core of iron laminate), two resistors, and four high-quality polypropylene-dielectric capacitors. (ICW Clarity capacitors are specified, though the caps I could see were marked “Bennic,” a respected Taiwanese brand.) All components are hot-glued to a circuit board mounted on the inner surface of the terminal panel. This panel has five binding posts: one pair each for the tweeter and woofers, and a fifth that grounds the amplifier’s output to the drive-unit chassis. Because I mainly used bridged amplification, I didn’t connect this terminal, but doing so with conventional amplifiers is said to reduce the noise floor by shielding the voice-coils from RFI. The internal wiring is specified as being silver-plated copper from van den Hul, though this is of relatively narrow gauge.
