ยินดีด้วยครับ 
Marantz สวยจริงๆๆ 
ขอบคุณครับ ที่ซื้อส่วนหนึ่งเพราะหน้าตามันดูเรียบและบึกบึนดีครับ
Marantz ตัวนี้เป็น pre-pro เหรอครับ สวยมากๆ หน้าจอเล็กดีจัง
โมอะไรไปมั่งครับ เสียงเป็นไง รอฟังรีวิว
ยินดีด้วยครับ
ใช่ครับเป็นตัว pre-pro ที่โมดิฟายโดยบริษัทชื่อ Cinemike http://cinemike.de/
มีการโม power supply เปลี่ยน cap filter เห็นบอกว่าเปลี่ยนไป 80 กว่าจุดแต่เขาไม่ยอมบอกชัดๆ มีรีวิวเมืองนอก ต้องเปิดด้วย google chrome เพื่อให้แปลให้ครับ
http://www.areadvd.de/lm/AV_Hardware/test_marantzav7005.shtmlMarantz has the AV-7005 did exactly what many home theater enthusiasts have always wanted: make a good surround receiver, throw out all the output stage related components and complements the fresh-baked precursor to symmetric pre-out ports. Of course, corresponds to the AV-7005 so still no Denon AVP-A1HDA, where the complete internal signal processing is completely symmetric (!) - But given the price range for what is offered is classified as excellent. The AV-7005 represents far more than a stripped AV receiver, but is through the XLR output and quality of power supply section in a meaningful form for his specialized role as a precursor.
As with all Cinemes tuning, Michael Krehl also sets the AV-7005 on the exchange of many individual blocks. This capacitors and filters are replaced with components that have better properties for the particular purpose. Each device is measured before and after the modifications to the relevant bodies, so that any fluctuations in series are considered.
The fundamental approach at the end Cinemes tuning can be found in the power supply area. This automatically each module in the unit benefited from a more stable power supply. As an example, we have received from the two upper images Cinemes, where a 3.3 V supply was measured immediately after the controller on the motherboard. This voltage supplies several chips, including the audio DSP, which is crucial for the sound quality on the digital level. The Cinemes modifications result in this regard a significant reduction in noise emissions 1 to 30 MHz (see next two measurement diagrams)
A significant part of the modifications can be found on the main board (digital processing). There are several voltage regulators that produce electricity from the power supply side, the dedicated 5.2 V lower voltages for the other modules. Since you all live off of the same input voltage, Cinemes aims its modifications designed to reduce mutual interference. Likewise, an efficient filtering is performed directly to the respective assemblies, which in terms of the EMC characteristics of great importance in order to couple any interference on nearby circuits.
This idea had even been the Marantz engineers - yet the result is only to the normal level and is a little more effort to achieve significantly better. The AV-7005 series does have no direct functional problems, but its optimal performance is slowed down. According to Cinemes efficient filtering / decoupling phonetically manifested by a higher resolution and an increased fine and gross momentum.
Total includes Cinemes tuning for the Marantz AV-7005 some 80 modifications that will cover the following areas: -
Optimization of the buffer for the digital-analog converter - approximation of the circuit for the operational amplifiers after the D / A converter (which is especially loud Cinem to the Center channel an increase cause of precision, as the production car is a deviation of the voltage that is compensated only through the software a bit) - Replacement of operational amplifiers to the D / A converters for low-noise and distortion-poor models - placement of the analog signal path with better components - the filtering of the power supply has been optimized for a reduced back-scattering of the device to ensure - The power supply for the analog audio circuits have been optimized and also better filtering - Basic optimization of the analog output stage (RCA + XLR Pre-out), an additional modification in the field of symmetrization (XLR)มีลูกค้าของ Cinemike ได้รีวิวตัว Cinemike Marantz AV7005 กับ pre-pro Denon AVP-A1HDA ตัว Top โมโดย Cinemike ที่แพงกว่ามาก
