Tube amp for Quad 989???

There is a special synergy between the Quads & ARC amps - the older ones not the VT100. The Quad's are not easy to drive correctly since their impedance curve starts off above 30 ohms down low and dips down to ~2 ohms at the top end. Use the 16 ohm tap from either a D115 or D70 and you'll have no problems with wieght or volume. I think most people who complain about the Quads have never heard them properly driven.

Synergy is right, and I have more than I ever imagined. Bought a pair of Antique Sound Labs 805 DT 50-Watt SETs. WOW. Connected to the 8-Ohm terminals, the system plays as loudly as I can stand with large-scale classical music. When my GEA-friend first heard the system, his jaw dropped open.

Impedance of the speakers is a huge factor in my experience. I tried the VAC 110/110, ARC VS55, and CJ MV60 and 60SE before settling on the EAR 890. A great combination for the 988s, and I would assume for the 989s as well.

Hi I have a amazing amp for those speakers........58 watts per channel...10HZ to 100,000HZ frequency range and with custom design circutry by Sam's Audio Labs.... It is a Citation 2 amp rebuilt by Sam himself..... take a look at the pictures here http://samsaudiolabs.com/catalog.html
