Well I confiscated my old Yamaha DSP A970 (SOund field processor integrated amp) from my dad's basement. I remember shelving it for a Denon Receiver because of Dolby Digital. I fondly remember how good it sounded. Well it took a day to get used to how different it was from my battery powered bare basic pre and amp.
SO many wonderful surprises getting used to it again. Tekton's are very efficient, but it appears they like a basic SS amplifier even if only 60 watts power. The imaging is rock solid. Not very wide, but I think that is partially my room. It has been a bear trying to nail the width, angle, etc to dial them in.
For example listening to O-Zone percussion groups "Jazz Variants" the room was shaking at times. Never heard that form my 8 watt amp.
I am hoping my next somewhat cheap and cheerful purchase will be a Record Doctor record cleaner or possibly sell some gear and buy a $399 iPhono to replace my Cambridge 651 pre. Though that pre has been blowing me away since I put my DL103 Cartridge on my dad's Technics turntable with a 1200 style S tonearm. BLOWN away nightly and even now.
