This could be the world Top 3 most musical single CD player on the planet!!! Available for sale a total cost of $24K USD Extreme Mod Wadia S7i Integrated CD/DAC with external PSU (Modification/Upgrade cost $10K USD see below) which brings an already outstanding cd player to most musical component ever produced by Wadia even performing equally to their $55K flagship model Wadia 922/931/270SE... The unit is in excellent condition both cosmetically and functionally (minor scratches on bottom due to the isolation cones) and extremely reliable German cd transport (cost only $300 for replacement transport and still available at Audio Research facility). This particular Wadia S7i has surpassed many uber cd players up to $25K USD which I had owned and compared to. Paypal +3.5%. Asking $13500 USD FIRM Include a brand new spare replacement transport for years of enjoyment. This is going to be a very intensive mod/upgrade. As we discussed this unit will be separate from the S7i and housed in itʼs own chassis. This will provide four benefits. a. Provide more room to add a separate power supply for the DAC and transport. b. Removing the toroidal transformers (two total) from the S7i will eliminate the magnetic problems that transformers impose on sensitive digital circuits. c. The cost of the upgrades you get to keep because they are housed in a separate chassis. Please understand some the parts being used are very sought after and are no longer available. Duplicating this power supply or bettering it in the future is very unlikely due to the unavailability of the parts. d. Sonics. After all this is the intended purpose of doing the upgrades. No doubt the S7i will be far more enjoyable to listen too. It will also allow you to use the S7i as a stand alone DAC if you decide to use a music server in the future. External Power supply Chassis DAC Power Supply - Involved with this upgrade is large inductors, capacitors (high quality Nichiconʼs), stepped bridge rectifier (not your typical rectifier) Bybees at the bridge rectifier. Toroidal transformer will have a mini “Stage” platform to house the transformer. Also the transformer will have a two part shielding applied. Mu metal will be around the transformer and the transformer will be painted. (Sonic benefits include increased soundstage, better layering, more ambient information, less grain, greater ease of the music, more slam and bass impact, increased resolution, and increased dynamics.) Transport Power Supply - This is a separate power supply from the DAC. It will be very similar to the DAC power supply. (Sonic benefits include increased soundstage, better layering, more ambient information, less grain, greater ease of the music, more slam and bass impact, increased resolution, and increased dynamics.) IEC Mount - This wire harness has a circuit board that goes to the two power transformer (one for DAC and one for transport). This circuit board will have added AC filtering with Mundof caps. (Sonic benefits includes lower noise floor, more inner detail and resolution). Power Supply Chassis - A separate chassis will be constructed to house the new power supplies. Besides the chassis there will be necessary hardware to fasten and secure the components being installed. As mentioned above two mini brass “Stage” platforms will be used to support the transformers. (Sonic benefits includes less distortion, blacker background, better imagining and focus, greater uniformity between the two channels, greater dynamics, more body and weight to the music) S7i Circuit board - Inside the S7i the critical circuit board will be upgraded. Larger value power supply capacitors will be installed. The vital Blackgate NX caps (approx. 20) will be used extensively on the circuit board. There is not one mod/upgrade company that uses these rare and almost extinct NX caps. These caps are what the DAC chips use and where this upgrade will bring it, and better it in some areas, to the level of the 9 series. Another sonic leap will come from adding five (5) high quality voltage regulators. The ones currently used in the Wadia cost around .75-1.00 ea. These regulators cost 60.00 each. There are a total of nine but we priced only five to keep the cost down. When I get mine done it will have all nine done. The DAC chips will be painted to eliminate EMI and RFI noise. They are so small you will not notice they are painted but the improvement is very obvious. (Sonic benefits includes instruments and voices are more defined, more air on top, better sound staging, and punchier bass).
