The OPPO BDT-101CI is a reliable high-performance Blu-ray transport designed for custom home theatres and professional applications. It shares many features of the BDP-103EU, BDP-103D, BDP-105EU, and BDP-105D models, yet there are some important differences between the BDT-101CI and BDP-103 series (including all variant models):

The design of the BDT-101CI focuses on its core function of disc playback. It does not have Internet streaming apps or inputs for external sources. The BDP-103 series is composed of full-featured universal Blu-ray players with Internet streaming apps and HDMI/MHL inputs.

The BDT-101CI features a modular design that can be customised for each installation's unique requirements. The BDP-103 series does not offer modular customisation, and each model comes with a standard set of features and performance specifications.

Because of its highly customisable nature, the BDT-101CI is only available through custom installers, and local resellers. 

Our recommendation for choosing the BDT-101CI or BDP-103 series is based on how you intend to install and use the player. If you need a simple and reliable universal disc player, the BDT-101CI may be a perfect fit. If you need a player with additional features such as network streaming and external signal inputs, the BDP-103(D) or 105(D) might be a better choice. If your primary use of the player is for listening to music and you will connect the player to high quality amplifiers and speakers, the BDP-105(D) is our recommendation for audio playback. Should your particular installation call for long cable runs, the BDT-101CI with an HDBaseT output module can get the job done.
