This review addresses the Boelen-modified EAD Ovation Plus’ 2-channel audio performance. Boelen-Noble Electronics offered me the Ovation in its original form for a first audition, which was returned later to them for modification. This review addresses performances of the Ovation in these two periods.For background on Boelen Electronics, please see the Introduction section in the Digital-Precise Review. BackgroundIn the 25 years since the first market appearance of separate digital-to-analog converters in the late 80’s to the present day, most manufacturers have been designing their products to serve 2-channel audiophiles, except for EAD (Enlightened Audio Designs).EAD was founded by Alastair Roxburgh and John Hagelin of Fairfield, Iowa, in 1990, until its acquisition by Alpha Digital Technologies of Ashland, Oregon in 2001. Since then, Frank Boelen’s Boelen Electronics had been offering modifications and repair to EAD owners, until that portion of the business was taken over by Greg Palma’s Noble Electronics in late 2005. Though no longer providing modification and repair to EAD owners, Boelen Electronics continued to market the Boelen Digital-Precise digital cable that Dagogo reviewed in March 2005.As the modification operations changed during the finalization of this review, Boelen/Noble will be mentioned simultaneously in this space.The PLUS modification performed on the EAD Ovation was a collaboration between the newly formed Boelen/Noble Electronics and Midwest Research Corporation, the latter of which was also founded recently, and headed by Greg’s brother, Robert E.

Palma Jr., MRC’s very own President and Chief Engineer. An important article authored by Robert E Palma Jr., titled Rocket Science Applied To Extreme Audio, will be published here on Dagogo shortly.According to Greg Palma, EAD’s then-Director of Manufacturing, and Boelen Electronics’ Director of R&D, now Noble Electronics’ President and Director of R&D, EAD began work on Rotel’s then-$499 RCD-855 CD player as its first modification project. In light of positive reviews on EAD’s Accu-Linear™-based modification, Greg was hired in April 1991 as the third member of the squad to help with the demand growth.EAD proceeded to create its first stand-alone DAC in the ensuing months and coined it the DSP 7000.

I have owned a T-1000 for many years although my component stereo has probably been used for less than 400 hours since 1996. Recently acquired an AR Ref 110 amp, an AR DAC-3 and an AR Ref II Mk II preamp playing though Spendor 69s with Sequerra Ribbon Tweeters (35 years old). But my T-1000 will only play the first 60 seconds of the first track on any CD I try to play. The 60 seconds are phenomenal, but a little short.

Can’t play any track beyond the first. Used a disk cleaner to clean the laser but it will not run through the cycle.

Do you do repairs on the T-1000 or do I need to look for a new transport? Thanks in advance for any help you can offer, Doug.
