Description
Teddy Pardo XPS-Plus for Naim ND Series Streamers (Analogue socket 2) Teddy XPS Power Supply Plus replaces Naim XPS for powering the Digital section of Naim Network players ND555 and NDS The TeddyXPS-Plus is a power supply that was designed specifically for Naims Network Players, NDS and ND555, where it will power those players analog section, in combination with the well-known TeddyXPS powering the digital section. The combination of TeddyXPS and TeddyXPS-Plus, makes for a two-box solution that is fully compatible with 555 power supplies, featuring our superb SuperTeddyReg regulator technology. For sale due to downsizing, my 2021;Very lightly used, Teddy XPS-Plus in excellent condition (RRP inc VAT and Shipping £1400.00) which performed brilliantly with my Naim ND series streamer at a fraction of the price of the Naim 555PS (RRP £7,499/£8,499). Yes in listening tests there is a significant uplift in sound quality when both the Anagolue and Digital sections of the Naim NDS (Sockets 1&2), were both powered externally with separate TP XPS power supplies. Make a big saving on this superb unit with no VAT or Import duties to worry about. Rack housed with no marks, scratches or other defects. Will be shipped in the original packaging and doubled boxed for secure shipment by next day courier. From a pet and smoke free home. MORE INFORMATION :- Other advantages over the Naim XPS include 1/2 size casework, no regular service required and absolutely no transformer hum. The Unit is not supplied with a Power Supply cable or Burndy cable. A regular kettle/computer plug can be used or an upgraded supply cable, although this is not recommended by TeddyPardo and I could not detect any discernible improvement in Sound Quality during a listening test. Burndy cables are supplied with the Streamer head unit by Naim or can be purchased directly from TeddyPardo.com. DETAILS : BackgroundThe NaimNDS network player can be upgraded in two levels of power supplies: Level 1: the NDS is powered by the TeddyXPS power supply, using a link-plug on power supply upgrade socket#2. In this case, the TeddyXPS will power both analog and digital sections. Level 2, by removing the link-plug, the TeddyXPS will power only the digital section, and the TeddyXPS-Plus will power the analog section, offering the highest level of sound quality at a very attractive cost. Seperating the analog and digital sections power supplies and using a combination of TeddyXPS and TeddyXPS-Plus is the most cost effective upgrade package to Naim NDS and ND555 network players. The TeddyXPS-Plus is based on the same regulator technology found in other TeddyPardo power supplies, with extremely low noise levels. The TeddyXPS-Plus can only be used with the Naim NDS and ND555, in a two box configuration along with TeddyXPS or Naim compatible supplies. InterconnectsThe TeddyXPS-Plus can be used with Naim Burndy cable marked #2, as well as TeddyPardo XPS-Plus Burndy cable. The EffectWhen using our two-box solution, a combination of TeddyXPS and TeddyXPS-Plus, the picture becomes much clearer, with a sharper soundstage, more detail, extended highs, extended and firmer bass, human voices sound more natural, and an overall smoother, and less aggressive and fatiguing sound. AdvantagesBetter sound qualitySmaller sizeNo transformer humDoes not require maintenance or recappingLower costIm already using Naim NDS with TeddyXPS, do I need to replace it ?Absolutely not. The TeddyXPS-Plus makes for a simple upgrade path to Naim NDS owners who use our TeddyXPS or any of Naims XP variants -- just remove the link plug and add TeddyXPS-Plus to NDS Upgrade Socket #2, with a dedicated Burndy cable, marked #2. Can I use TeddyXPS-Plus together with a Naim Power Supply ?Yes, the TeddyXPS-Plus makes for a cost effective upgrade path even when you are not using TeddyXPS, just remove the Link-Plug from Upgrade Socket #2, and plug in the TeddyXPS-Plus with Burndy Cable #2. Can I use TeddyXPS-Plus with other Naim Network Players (e.g. NDX-2 etc) ?At this stage, the combination of TeddyXPS and TeddyXPS-Plus can only be used with Naim NDS and ND555. Sound In general, you’ll experience more clarity, tighter bass, more details, better dynamics, natural voices, better soundstage and PRaT . In a nutshell The power supply has a major effect on sound quality. Ideally a power supply should contain only clean DC, but in practice every power supply, including batteries injects noise to the amplification stages. Any noise on the power rail translates into distortion, coloration, and sound which is less natural. When the AC voltage is rectified, a ripple is added to the DC voltage. This ripple translates into noise at all audible frequencies and has a negative effect on the sound quality. The better the power supply can filter this ripple the better the sound will be. To get an idea of how much the power supply can affect the sound quality, suffice to mention that almost all NAIM preamplifiers are based on the same amplification circuitry, and differ in their ability to connect more or better power supplies. The amplitude of the ripple mentioned above decreases with the size and quality of the smoothing capacitors being used. Naim Audio uses a brut force technique for the HiCap and XPS; they use a 500VA transformer and rely on large low ESR capacitors. Not only that this technique is less effective in noise filtering, but over time, being electrolytic capacitors, the quality of these capacitors decrease (ESR increases), and as a result the ripple increases, this is the reason for which the HiCap and XPS require re-capping every 10 years or so. The most common way to reduce ripple is to use a linear voltage regulator such as the LM317 used for the HiCap and XPS. All linear (feedback) regulators however, including the superior SuperRegulator, have a limitation which is inherent to the way they operate; they can only fix a problem after it occurs. Since the speed in which they can fix the problem (regulate) is constant, their ripple rejection capability decreases with frequency. The LM317 has a ripple rejection of around 80db at 50Hz, which drops to merely 20db at very high frequencies (note that a -60db difference means x1000 times less!!!). The SuperTeddyReg : The regulator is the heart of the power supply. The TeddyXPS is designed around the SuperTeddyReg, a regulator that has been developed especially for this power supply and surpasses any regulator that I have tested so far. Thousands of the original TeddyReg regulators have been sold during the past months via the PinkfishMedia DIY forum. The Super TeddyReg is an evolution of the TeddyReg and provides even better performance. The innovation in this power supply is the incorporation of a very effective low-pass filter that in conjunction with a voltage reference provides a theoretical (impossible to measure with ordinary equipment) ripple rejection of more than 120db over the entire audible spectrum and above 1MHz. This powerful filter allows using smaller transformers and smaller smoothing capacitors. Since it does not rely on the large smoothing capacitors to eliminate the noise, it does not require re-capping as the quality of these capacitors decreases. The other advantage of using smaller capacitors for the filter is that capacitors other than electrolytic can be used. Electrolytic capacitors are limited in high frequencies, and have leakage noise. This PSU is using a combination of Tantalum, Polyester, and X7R ceramic capacitors capable of filtering very high frequencies (over 1MHz). Surprisingly, filtering high frequencies even above 100 KHz is clearly audible. The Case The TeddyXPS-PLUS is built in an elegant black aluminium case (similar to the DualTeddyCap), saving space on your expensive hi-fi rack, and saving negotiations regarding the introduction of another large black box… Specifications: Voltage: 220-240V Size: 24x16x6 cm Weight: 2.4 Kg

TeddyCap mit 2x24V für Naim NAC 62 & 72Ordentliche Alternative zu HiCap o.ä. die ja in ihrem Alter gerne mal ziemlich ausgelutscht sind :-) Als recapped dann aber leider doch recht teuer. Einfach mit dem 5 Pol Kabel (Latch Lock) die NAC mit Strom versorgen - ist im Lieferumfang enthalten. Die Endstufe wird mit dem originalen SNAIC4 ebenfalls ans TeddyCap angeschlossen! Bei mir kommt das Netzteil nicht mehr zum Einsatz - meine Naim sind gerade frisch von der Revision gekommen und erst einmal eingelagert Von Privat ohne Garantie, Sachmängelhaftung, Rücknahme.
