Posted: Thu Oct 10, 2013 5:30 pm
Hello everyone,
many many years ago i started in this (the original one) forum. 7 years ago i bought a troubled Grand which needed some loving. After 7 years, she is finally done and here is the result. List of equipment and pics. Enjoy
Apogee Acoustics Grand (New TW, MRT, BASS Ribbons)
NAT Utopia Single Ended Triode Preamp; No Feedback
Custom Developed CAP Coupler
Monarchy Audio NM24 Tube DAC (Tesla 6922)
Monarchy Audio DIP (Jitter Killer & Masterclock)
PS Audio P1000 Powerstation
NAT Phono Signature (Battery Powered; Single Ended Triode; No Feedback)
SME 20/2A (SME V Gold ARM; All NEW Suspension and OIL)
Ortofon Statement (Low output MC System)
2 Mono NAT Audio SE3 Midrange AMP (Single Ended Triode; VT4C Based; 54 Watt Class A)
2 Mono NAT Audio SE2 Midbass AMP (Single Ended Triode; VT4C Based, 52 Watt Class A)
2 Mono NAT Audio SE1 Tweeter Amp (Single Ended Triode; VT4C Based, 15.4 Watt Class A)
Six Custom Developed DC and Distortion Watchers with Emergency driver shut off function
Virtual Dynamics cabling for electronics (power and interconnects)
Behringer Ultracurve DSP (Digital only) adjustment to lower subwoofer output

PS: I want to thank the following people:
Frank from the HI-FI Burg Zürich for the on-site ribbon installation until late in the night
Mr. Bill Orner- for finding the schematics for the Apogee Grand. Without that it would have been much harder to get this beauty back up
Jason Bloom, Leo Spiegel, Gary Walker, Andy Lewis, Mike Daniels and Todd Eichbaum for building, what is to me, the best loudspeaker ever designed.
Graz - For providing me the new ribbons for my speaker, without him it would be just a pile of steel and magnets
Brad (Morricab) - For his patience and not giving up on me even tough i went back to Krell twice
W&W Audio in Holland - For letting me try tons of electronics and offering me not only good service but also great human interaction and guidence
Dipl. Ing. Ralf Kassel (Germany) for fixing my Grand electronics and for developing custom DC protection boxes.
My Girlfriend - For not killing me as i spent weeks in the basement trying to fix the speaker and lifting hundreds of pounds of amplifiers with me up the stairs
PS: In case images dont show
