NAIM 的nac282＋nap250＋hicap组合，推思奔达SP100R [复制链接]

玩Naim, 最多只能玩到此点. 

250使用了秘密武器007晶体管. 是参考级的第二阶梯.

再往上, 性价比就低了.

NAP 250 power amplifier
The newest Naim NAP 250 delivers speed, power and agility providing exceptional detail and musicality in a package built to swing for another 25 years. For 27 years the NAP 250 has been at the heart of thousands of high-quality audio systems around the world. During the years of research that went into the NAP 500, many technical developments came about that could be successfully applied to the NAP 250. Many of these developments, along with the elegant new styling have been incorporated, resulting in a new Classic line-up. Like the flagship NAP 500, and the NAP 300, the NAP 250 uses a new circuit design with improved earthing arrangements, built on a very high quality, anti-resonance main audio circuit board. The NAP 250 uses the same 007 transistors that were custom-designed for the NAP 500. These outstanding components each provide up to 80 amps and 350 Watts, negating the need to use parallel pairs of transistors (which always have a negative effect on sound). Additional 007 transistors are used in the fully regulated power supply, ensuring the very best performance. Anti-vibration, resonance-controlling feet serve to protect the sensitive internal components from resonance and microphonic vibration. A new top-quality transformer is used providing the ability to deliver more than 15 Amps and swing a massive 400VA on transients. The NAP 250 is stable into any load and able to drive a 2-Ohm load for long periods of time.	click image to enlarge click image to enlarge

CDX2 CD player
Extensive research carried out over the last few years has been fully employed in producing the integrated CDX2 CD player. Naim has made as few compromises as possible to ensure that the CDX2 offers complete musical satisfaction, rivalling that of the finest analogue turntables. Integrity and stability of the RF signals read by the laser have been prime design considerations. A suspended transport and low mass magnetic clamping system ensures that the disc spins accurately and silently, unhindered by mechanical resonance. The mass of the custom-made glass reinforced front-loading drawer mechanism has been carefully calculated to optimise rigidity and isolation. The addition of anti-vibration, resonance-controlling feet compliment the elegant new cast and extruded anti-magnetic chassis to protect the sensitive internal components from resonance and microphonic vibration. Additionally' the internal shielding has been improved bringing about further upgraded performance and lower noise. Paths between critical components are as short as possible to preserve delicate signals and each stage of the circuitry is powered by a separate regulated supply. Correct earthing is used throughout and there are no digital or headphone outputs. Both the transport and chipset have been upgraded for the CDX2. The HDCD decoder/digital filter is only activated when playing encoded discs. Eight-times over sampled data is then sent to two (one per channel) Burr Brown PCM mono D/A converters. A separate, fully optimised master clock controls all main digital functions, and the clock configuration and layout are engineered to minimise jitter. A seven-pole analogue filter follows the DAC to remove spurious noise. The CDX2 has a fully double-regulated power supply with 20 low-noise, regulated power supplies on the main circuit board, plus a separate supply on the servo control board and another on the display board. It is a stand-alone, mains powered machine, which may also be used with the XPS ultra low noise power supply, providing a substantial improvement in sound quality. Naim research has proved that divorcing the main power supply from a CD player is wholly beneficial, whereas the more common arrangement of housing the converter circuitry in a separate box causes many problems. The Naim XPS power supply is extremely sophisticated with six separately regulated, ultra low noise outputs, featuring a toroidal transformer and six power regulators. This ensures complete stability of the ultra-sensitive circuitry in the CDX2. The same external supply is used with the Naim CDS3 CD player, thus providing a further possible upgrade path from one player to the other. All main control functions are handled by a microprocessor running Naim-written software. Every aspect of the SAA 7376 servo controller/decoder functionality is under software control: Naim-written codes allow maximised performance in all areas. For example, the transport parameters are optimised for each disc as it is loaded. In addition, special care has been taken to ensure that the player/user interface is as logical as possible with extra features such as "display off" (for improved sound quality) and program cancel, where tracks the listener does not want to hear can be quickly selected. Worthwhile user features have been added: in addition to a clearer layout of the back panel, RC5 and optional RS232 ports have been fitted, allowing seamless integration into even the most complex of home installations. In common with the flagship NAC 552 preamplifier, the CDX2 has user-configurable outputs, allowing a choice between the preferred DIN output and RCA phono connections, allowing the CDX2 to be used with a wide range of other manufacturers' cables and components. This machine is designed to be the best in its class, incorporating genuine technological advances to provide a thoroughly enjoyable musical experience. Ultra-high quality CD player. Twenty power regulators make up a fully double-regulated power supply with exceptional dynamic stability. User-configurable versatile (DIN/phono) outputs. Full infrared remote control. RC5 input for wired remote control in complex installations. Optional RS232 input/output for use in full home automation systems. The optional Naim XPS power supply provides six regulated power supplies; this significantly reduces supply noise for all circuitry. The Naim CDX2 plays music from CD in a wholly natural, believable way, providing the same involvement and enjoyment as a high-end analogue source but with tremendous consistency and reliability.	click image to enlarge click image to enlarge

XPS power supply
The importance of power supplies has been close to the heart of Naim philosophy for over twenty years. Naim research proved that divorcing the main power supply from a CD player is wholly beneficial, whereas the more common arrangement of housing the converter circuitry in a separate box causes many problems. The Naim XPS power supply is a very sophisticated power supply with six separately regulated, very low noise outputs, featuring a toroidal transformer and six power regulators. These supplies are branched and re-regulated, some twice in the CD player. The addition of anti-vibration, resonance-controlling feet compliment the elegant new cast and extruded anti-magnetic chassis protect the sensitive internal components from resonance and microphonic vibration. This supply is required and comes as standard with the CDS3 but can also be added to the CDX2 CD player, providing a substantial improvement in sound quality and a possible upgrade path from one player to another. Timing, dynamic range and clarity all significantly improve by adding a Naim XPS to a CDX2. Complex passages become more understandable, bringing far more involvement and enjoyment from the music. Ultra-low noise CD player power supply. Huge toroidal transformer and smoothing capacitors provide exceptional dynamic stability. Six power regulators feeding six completely separately regulated power outputs. The new Naim XPS sets the music free, making it an incredibly effective upgrade to the Naim CDX2, and a critical component of the Naim CDS3.	click image to enlarge

引用第0楼sanyue于2008-04-29 11:09发表的 NAIM 的nac282＋nap250＋hicap组合，很快可以抵达三越 :
可以用来搭配SP100R。
从NAIM的产品排列来看，282+250应该是属于力度型的，和122X+150X的感觉是一样的，202+200就相对温和一些。

怪不得，202+200也太温和了，听了不是很喜欢！

现在越搞越大了！
