FiiO K7 BT

Sinds de K5 Pro een hit is geworden op de markt, heeft FiiO hun investering in desktop DAC en hoofdtelefoonversterkers vergroot. De K9 Pro was een geweldig bewijs dat ook erg populair was onder high-end gebruikers. Tussen deze twee producten ontbrak echter nog steeds een DAC/Amp om de stap te overbruggen. Deze keer checkt de K7 in om de nieuwe referentie basismodel voor een gebalanceerd desktop/amp in de FiiO familie te worden!

Anders dan de K7, gebruikt de K7 BT de QCC5124 Bluetooth-chip, die LDAC/aptX Adaptive/aptX/aptX HD/aptX LL/AAC/SBC en andere high-definition Bluetooth-formaten ondersteunt. Draadloze verbindingen stellen u ook in staat om Bluetooth-transmissie met lage latentie en hifi-geluidskwaliteit te krijgen. U kunt de Bluetooth-firmware upgraden, het Bluetooth-formaat selecteren, PEQ aanpassen enzovoort via de FiiO Control APP om de draadloze ervaring verder te verbeteren.

De K7 volgt dezelfde audio-architectuur als in de vorige high-end K9 Pro, een echt gebalanceerd circuit bestaande uit DAC + LPF + Volumeregeling + Bufferversterker + Voorversterking + Hoofdtelefoon. Audiosignalen van elk kanaal worden verwerkt door de volledig differentiële audio-architectuur.

Wat de versterker betreft, past de K7 de THX AAA 788+ toe die werd ontworpen voor desktop apparaten. Onder een belasting van 300Ω bij 1% vervorming van elk kanaal kan hij 560mW uitvoeren, en 2000mW bij een belasting van 32Ω bij 1% vervorming van elk kanaal. De linker- en rechterkanalen van de DAC zijn elk uitgerust met AKM's nieuwste AK4493SEQ DAC-chip, voor een klassieke hoge kwaliteit en warm geluid. Wat betreft de USB decoderingschip, de XMOS XUF208 in de K7 maakt gebruik van dubbel klokbeheer om verschillende muziekformaten met gemak te verwerken.

De K7 heeft een voedingsontwerp dat bestaat uit meerdere onafhankelijke trappen, waarbij de spanning van elke trap wordt geregeld door LDO's met weinig ruis. Dit voedingsontwerp wordt gevoed door een externe 12V schakelende voeding. Al met al is het vermogensontwerp van de K7 ontworpen om overvloedig en schoon vermogen te leveren voor een buitengewone luisterervaring. Om ervoor te zorgen dat de K7 altijd op zijn best werkt, zijn de oververhitting-, overbelastings- en DC-beveiligingssystemen er om u een meeslepende en prachtige luisterervaring te bezorgen.

Daarnaast is de K7 voorzien van een volledig aluminium legering constructie, zorgvuldig afgewerkt met CNC en andere processen. Het kleine ontwerp is slechts 55mm hoog. In combinatie met de briljante RGB-lichtshow past hij perfect op moderne bureaus.

A masterfully falsified history of the late Soviet developments
Format: Paperback
This book represents academic propaganda, providing some interesting insights into important events. Some details are true, but some crucial details are omitted. It represents a sanitized version of Russia's modern history. It provides misleading information about Gorbachev's constitutional reforms, aimed at partitioning of 15 republics into 53 confederation entities. Originally, the targeted republics were Kazakhstan, Moldova, Georgia, Azerbaijan, Ukraine, etc. Those conflicts were manufactured by the Soviet center to discredit "nationalists," facilitate the partition of national republics, and grant Moscow right to protect ethnic minorities. According to Starovoitova, Bakatin, Yakovlev, and a few other primary sources, the Soviet security services led special operations in the Caucasus and Central Asia to provoke those conflicts. Zubok avoids citing those parts. Using the imperial approach of "divide and rule," Moscow attempted to become a peacekeeper in the conflicts it created between different ethnicity. In addition to fragmenting the republics with well-developed national identities, Gorbachev's new constitution would revoke their right to leave the USSR, written in Lenin's 1922 Constitution (Shakhnazarov, 1992). Zubok does not explain any of it. His book is an effort to protect the truth and conceal facts with Russian myths and lies about nationalism (also referred to as Nazism). Notably, Zubok does not recognize non-Russian republics and describes them as "territories." He mentions Pitsunda as a resort on the Black Sea, not as Georgia. For lying about the genocidal ethnic cleansing conducted by the Russian military against the Georgian population of Abkhazia, Zubok owes apology to the victims of conflicts and wars initiated by Gorbachev and carried on by Yeltsin. The story about "the hardliners coup against Gorbachev" is also a big fat lie. American scholars, Amy Knight, John Dunlop, and William Odom provide more accurate insights. For Russian sources, read Marshal Shaposhnikov or Aleksandr Lebed's memoirs (1995) and listen to Gennady Yanaev's interview (2009). According to Mitrokhin archives (original), the August 1991 coup was an active measure the KGB developed per Gorbachev's request. The so-called coup was part of Gorbachev's constitutional reform, which would lead to the removal of unfriendly leaders (including Yeltsin) from the republics. It failed because the Soviet military brass, foremost Pavel Grachev, had defected to Yeltsin earlier in 1991. When you read a book by a seasoned Russian propagandist, like Zubok or Trenin, take it with a grain of salt, because it will always contain a mix of lies and truth.

An important work and worth the time.
Format: Hardcover
Real scholarship addressing difficult but important topics in history, economic history, and development. What every economist should read to think much more deeply about how institutions, culture, and human agency interact. At the same time, scholars like the three co-authors demonstrate that there still remains the possibility of doing work that isn’t larded with ideological or activist posturing. Highly recommended.
