I’m not going to state the Oppo 105 is one of the best CD/SACD players mainly because I haven’t listened to enough hi-end players to know. OTOH, I believe I’ve never felt the need to upgrade to another player because its such a high quality performer on both.
I also think it’s unfair to compare the multi-talented Oppo 105 player to much more expensive players that are only capable of playing CDs. The Oppo 105 is a high quality universal player that can playback CD, SACD, DVD-A and CD-ROM audio discs as well as up to 1080p DVD and Bluray video discs. It has separate audio and video circuit boards, a built-in QDEO up-sampling video processor, has both fully balanced XLR and unbalanced line-level RCA outputs and utilizes 7 high quality and expensive ESS Saber dac chips.
I’ve used my 105 as a limited preamp, 5.1 surround sound processor, a stand alone hi-res 32 bit dac for up to 192 KHz WAV files, a music server/player with an attached NAS controlled by a wireless laptop, a music streamer, a high quality headphone amp as well as a CD/SACD/DVD-A audio disc player and a 1080p DVD and Bluray video disc player, all purchased brand new about 6-7 yrs ago for $1,200.
Sure, you could likely find a much more expensive CD or SACD only player that may marginally outperform the Oppo 105 in sound quality but it certainly won’t be this versatile with the exception of a Modwright modded unit which I’ve, unfortunately, never heard.
I’d suggest you either have your 105 modded or buy a NAS with a laptop or iPad to control everything, hook all components to your wi-fi and enjoy the ultra convenience and excellent sound quality of having your entire music collection accessible in the form of a digital computer audio system. Take advantage of 21st century technology and enjoy the convenience and high resolution sound quality of a modern jukebox.
