The Arcam Delta 170 is one of the first examples of an entirely new product category: CD transports. The concept of different CD transports having different sonic qualities is vexing. It is a simple matter to prove that the bit stream contains identical data from virtually any CD transport (see Industry Update, Vol.12 No.8). According to Arcam, development of the Delta 170 was spurred by audible differences among transports heard by dealers, customers, and Arcam staff. The possibility that CD transports have their own sonic signatures is intriguing.On the other hand, outboard D/A converters clearly make sense. CD-player (and DAT) owners can enjoy the improvements offered by the latest technology just by replacing (or upgrading) their D/A converters, provided their players have digital outputs. Digital output ports are becoming increasingly common: in early 1987, just 12 players had digital out, the number rising to 50 by early 1988. Today, the figure is over 100, with 29 also offering optical digital output (see Sidebar Into the Optic).The Delta 170 is based on a Philips single-beam mechanism. Unlike many other Philips-based players, Arcam has completely redesigned the machine, keeping only the basic laser assembly (CDM 1 Mk.2) and Philips data-recovery chips. The entire mechanical assembly is mounted on a vibration-isolated and damped subchassis. Compared with a Philips CD 880 transport, the Delta 170 appeared much more solid. For example, the metal supports that anchor the assembly to the chassis are larger and heavier. Arcam has put much thought and effort into this machine.On the electronics side, the Delta 170 has some interesting design features. These include an optically isolated master clock and dual power supplies, each with its own transformer. One supply provides DC to the master oscillator and digital output stages, while the other serves the player servos and microprocessor. Digital output is in S/PDIF format from an RCA jack, or optical EIAJ (Toslink) connector.

This is my Arcam CD 72 (CD72T) that I have owned since new.This is the text version with the enhanced display Originally purchased from Sevenoaks Plymouth by me in 2001!I have always looked after this player and it has always performed impeccably.There are absolutely no marks on the player at all. The drawer mechanism still performs as smoothly as the day that I purchased it.The original remote is included, fully working. The remote has never really been used because I have other Arcam equipment which have their own remotes that can control the CD player.I will include the mains lead and owners handbook.All of this will come in the Arcam original box. This was always an excellent sounding player, Please read reviews.Uses a 24 bit Burr Brown multi level delta sigma DAC explained in more detail on the Arcam site here: https://www.arcam.co.uk/product,diva-cd72-t-cd-player.htm Also benefits from an optical or Co-axial digital output should you wish to use your own DAC. You are welcome to collect locally (in fact I would encourage it) if you wish.

Arcam AVR850 A/V Receiver - Black - Preowned - Boxed + Remote AVR-850. Slight scratch on the top left (picture). The scratch is minor, and the flash made it look 50x worse. Can you send more photos if you like. Also, one of the 12v triggers has stopped working (could be a setting, not sure). The other trigger works fine. Unit is in fine working order, and probably used for about 30 hours max in a cinema room. Collection preferred as postage is high.
