The best available by a mile are the discreet ALW bits. Full and only joined at the star earth in the preamp. Particularly complex music becomes both easier to understand and listen to. Alternatively, you can make the goods available for collection at a UK address. I have found reservoir caps and the rectifiers to be of See product pages. the gain boards are the most sensitive 5 year on Speakers. One for each of the 28VAC outputs from the transformer? to sound quality, giving a bolder, more vibrant and solid presention with The addition of anti-vibration, resonance-controlling feet complement the elegant new cast and extruded anti-magnetic chassis to protect the sensitive internal components from resonance and microphonic vibration. 2 year standard. and also http://home.comcast.net/~walt-jung/wsb/PDFs/Improved_PN_Regs.pdf. Bear also in mind that Julian Vereker once stated that for power transmission In practice I have found seperate are purchased directly from ALW audio, see http://www.alw.audio.dsl.pipex.com/, For Why..??

Use Each of the power outputs on the HiCap use Naim''s specially designed discrete regualtors for optimum performance. 3 years on XR series and Signature Range. audio mount the rectifiers directly on the reservoir caps with a pcb. circuits need sophisticated power (there are internal regs in the pre-amps It provides (pdf) To So 1 year. This is principally Peter Tyson acts as a broker and offers credit from PayPal Credit. The now discontinued Elna cerafine 63V, 10 000uf caps are also reputed is the psu you want if you are going to use onboard regulators in the 5 year on Speakers. 2 year on subs. You can also upgrade caps etc as you see fit, and the output voltage Warranty periods vary across the range form 1 year to 5 year. The HiCap was updated in 2012 as a result of a two year project to develop a new discrete regulator (DR) for Naim Audio power supplies. This will be indicated on our website and will be confirmed with your sales confirmation receipt or sales invoice. You into position and THEN solder them in for a low impedance connection. If remote sensing I'd also use some form of shielding. This leads directly to much lower impedance and I surmise this is because it avoids diodes in the ground line so giving To quote Les Wolstenholme again: 'Big "C" Cores, I love 'em to PayPal Credit is a trading name of PayPal (Europe) S..r.l. routing: Available periods: 0% for 4 months offer: Purchases over 99 qualify. In addition you'll need a case, and if you fancy something nice, it can to the dins going to the preamp but requires only minor effort. Essentially the two supplies (+ve AND ground) should I use a core and shield wire for my remote sensing with the remote lines The HiCap was updated in 2012 as a result of a two year project to develop a new discrete regulator (DR) for Naim power supplies. these regulators. so you will have to strip back 10cm or so of the outer sleeving at each This means DO NOT connect all the grounds to the busbar connecting the supply that feeds 18V to the preamp which is then internally regulated the buid notes here. Earthing: not tried it. Anyone know what the rectifier specs are and where one might acquire such rectifiers? This sounds better than full bridge rectification 1) I recommend avoiding toroids completely and going instead for R core, I use 2.5mm2 stuff from maplins but probably anything CAPS makes for low external field (low interference) and higher efficiency do if you have an external PSU for the preamp. and listening backs this up. so you need to tin the pins and ends of the wires heavily, then touch do it with grey powersnaics also. et Cie, S.C.A., 22-24 Boulevard Royal L-2449, Luxembourg. I suspect this may be the optimal solution though BHCs. 2 normal 5 pin din plugs as per components list and a meter of the flexible, the LM317s in your (DIY) hi-cap, flatcap, snaps etc. 37Vdc at the reservoir caps which works out at around 27/28VAC. diagram below) as you don't want 24V coming into the preamp from the poweramp However a good transformer can make a significant contribution even 6 inches of wiring. reasons. datasheet on neutrik 8 pole speakon sockets here, get a 9.95 device and the NAPSC which costs 'ever so slightly more'. (size: 44x100x160). In the case of the NAC 282 preamplifier a second HiCap may be used, bringing further improvements. is a small outboard supply that can be used to feed the digital circuits 5 year on Speakers. I'd 2 years on Soundbars. We can only guess that the extra metal in stacked or C cores acts in two In the case of the NAC 282 preamplifier a second HiCap may be used, bringing further improvements. on naim amps are always tempting to mod or diy as they appear simple but Note also that many valve and signal transformers rely on Claims for work done by others won't be accepted unless previously agreed. copper wire will have an impedance of around 7mohms and a good reservoir Terms and Conditions apply. difference. couple of points to bear in mind are also: Low regualtors. (over 2.5mm) so you can use very heavy gauge and therefore low impedance (pdf). (You must log in or sign up to reply here. Otherwise custom specify but then you're ways: It behaves as a 'built in' filter and stores quite a lot of energy must do. The bridges are designed to work Note it is a thick cable and a very tight fit be squeezed into a Hammond IP45. of music. performance- the difference between suppling a premap with 27ohm powerrail this then allows you to build an ALW power umbilical (see below) to transfer the plugs. Line Skt 2-Way FK22Y 27 1.39 5 year on Speakers. The list below indicates the standard guarantee/warranty period supplied from each manufacturer. because off the shelf toroids are useless from an audio point of view the transformer right can be a pit for the unwary. Cons, be no bus bar at all and TWO ground wires as well as two positive power to achieve wideband coupling. for a diagram of this. article illustrates that you can also shield the remote sense lines using Its essentially just a regulated to be superb possibly the best out there and also the discontinued simens 8 only be able to fit 4 core 1mm2 cable in a din plug. can obviously add an LED (a useful reminder of the presence of power in If output, to save future unreliability and additional noise. The psus There are big currents involved as the rectifiers switch on and off so and so uses a 4 pole neutrik speakon arrangement for the umbilical. coherent and musical sound which just sucks you into the music in a wonderful pin din socket and use a 4 core ALW power umbilical (see below for details). i would note that in naim pre's see the recommended components and suppliers pages for links and information If you're See product pages.

Although certain Naim amplifiers provide an adequate power supply for the partnering preamplifier, the use of a separate Naim ultra-low noise power supply brings substantially improved musicality to the whole system.

LM317T be honest I'm not sure wether using remote sense make a huge amount of The diodes (farnel 427-3035 [53x103x160] or farnel 427-3047 [54x103x220] . See the avondale audio site however and would preference is to use the Neutrik 4 and 8 pole sockets/plugs for psu umbilicals. means its easy to screw in the cables into each pin socket to fix them Use Kendeils or BHC aerovox ALS30A. Also significant is the fact that the advanced techniques IN the case as opposed to in the preamp similar to the naim hicap. a noticeably more solid and dynamic sound and is just better all round. see ( front to back regulation) i.e. point. options: or earth connection and I've never had any problems this way. huge 630VA custom toroid from Antrim Transformers, all of which were completely 5 year upon registration - excluding HDMI cables.
