When talking about CD quality we usually mean original files used, be it the original master tape (RCA Living Stereo, Mercury), or AAD vs. DDD recordings, and/or mastering engineer: Steven Hoffman, Manfred Eicher, Doug Sax, “Prof” K.O.Johnson, etc, etc…   Other-times companies make a name for themselves by paying special attention to CD mastering chain: Esoteric SACDs, JVC-XRCDs… Mobile Fidelity gold CDs became highly collectible because of the mastering quality but also because of the layer of Gold instead of Aluminum used during CD production. Wadia 781i revealed yet another step in CD production chain where things can go wrong: final CD pressing. This step takes place at some anonymous plants churning out CDs for the major and audiophile labels. Continue reading THE GOOD, THE BAD AND THE UGLY. CD PRESSING QUALITY

Upgrading Naim Stageline phonostage

Naim Stageline is a joke of a  phonostage, but when combined with Hi-Cap power supply it gains both in weight and in price points. Once I switched from VirtuosoWood MM to a MC cartridge, “Stageline N” went into storage and “Stageline S’ took its place.

For my cartridge,  AQ 7000 Fe5 (made by Scan Tech = Lyra and periodically sent to Lyra for rejuvenation), “Stageline S” (470 Ohm load)  is recommended. My first  impression of AQ/Stage-S was that I should immediately revert back to Virtuoso Wood and Stageline N: sonically my Sondek became “dead”… Continue reading Upgrading Naim Stageline phonostage

The most beautiful Discman in the World. Loewe CD-100

Here is the Snow White:


It must have been kept in storage until the grease got stiff, then played… once! Sled gears were immediately broken and so the Sleeping Beauty was packed and stashed away for a few decades…. then posted on eBay.  I was the one who bought this beautiful paperweight.   Continue reading The most beautiful Discman in the World.

Nakamichi decks and OCD – Orange Caps Disease

Matured and well-nurtured obsessive-compulsive disorder (OCD) had pushed me towards Nakamichi decks. Beautiful TEAC A-100 was more than adequate for my needs of making tapes to be played through a boombox. But how could I miss the chance to buy Nak LX-3, and then LX-5? LX-5 was professionally calibrated for me by Willy Hermann, but LX-3 I decided to fix myself.  Getting $100 Service Kit from eBay member revox-de was the first step:

A few weeks of pain and suffering resulted in a beautiful-looking (and up to specs) deck:

PCDP Components Table in MS Excel format

PCDP Components Table in PDF format

Original table can be found at I transferred data into MS Excel and then sorted Discmans by the year.  Some info on Sony Discmans was borrowed from; other-times extracted from Service Manuals or from the photos of the actual items undergoing surgery on my workbench. Excel file is updated each time I get a new Discman, PDF file updated only occasionally



Philips/Magnavox D6800 restoration

D6800 shall never win any Beauty Contest: it is just too big and chunky. It was designed for portable use, and all 6xAA (!) batteries should be loaded inside the player.

As already mentioned here, D-6800 has one of the most powerful headphone amplitiers among Discmans. Officially it is rated as 20mW into 32Ohm, but my own tests show the same numbers as for Sony D-50MkII and Technics SL-XP5 which are  rated at 30mW/32Ohm.

Bad news: absolutely ALL D6800 are dead by now… Continue reading Philips/Magnavox D6800 restoration
