The top cover was 120 degrees Fahrenheit within a few minutes of being turned on. Linear power supplies have lower efficiency than switch mode power supplies, therefore more of a LPS's energy is converted to heat. I did not hear further improvements due to additional playing time after that.Īll those ventilation holes are not there for show. Clarity and detail improved after 24 hours.

TeraDak recommends a break in period of one week. The DC-30 is encased in a high quality machined aluminum chassis. The addition of the TeraDak linear power supply caused the external drive's sound performance to leapfrog over that of the internal drive.įigure 1. However, when the external enclosure's upgrade USB 3 cable and upgrade power supply were taken away, music from the internal Seagate drive sounded better. My listening evaluation methodology and the musical selections used are discussed in detail in the original BDP-3 review, therefore they will not be rehashed here.Īt the end of the Seagate 5 TB hard drive review, I noted that I heard no difference between music files played from either the internal Seagate drive, or the external Western Digital Black 6 TB drive in its upgraded enclosure. The third addendum, a review of the Seagate 5 TB 2.5" hard disk drive, is here: The second addendum, a review of the iFi Audio Mercur圓.0 USB 3.0 cable, used between the external hard drive enclosure and the BDP-3, is here: The first addendum, a review of the iFi Audio iPower power supply used with BDP-3's external hard drive enclosure is here: This review will be more meaningful if the BDP-3 review, and first three addendums, are read first. Music files for the player are contained in a 6 TB hard disk drive, which is contained in a Rosewill Armer RX304-APU3-35B external hard drive enclosure.

This review is the fourth addendum to my review of the Bryston BDP-3 digital player. The TeraDak DC-30 ($150) offers high build quality and high performance. Linear power supplies are more suitable for audio applications due to their significantly lower output noise and isolation from AC line noise. Accordingly, the quality of DC power supplied by it is affected by AC noise components. Although the iPower power supply facilitates better sound than the stock power supply, it is still a switch mode power supply like the stock power supply. Very good results were achieved by replacing the stock generic "wall wart" power supply of my music library's hard disk drive enclosure with a lower noise iFi Audio iPower power supply ($49).
