Re: Tannoy Turnberry HE and Classé CP-35/CA-101

Up until April this year, I had, for 5 years, been driving a pair of Tannoy D700's with a Classe' CP-50 & CA-100 combo. I was reasonably satisfied with this pairing, until some burglars forced the replacement of the Classe' pre/pwr combo.

The insurance pay-out allowed me to make some small changes:

a. Classe' CP-50 replaced by Classe' CP-500
b. Classe' CA-100 replaced by Jeff Rowland Model 201 monoblocks (x2)

What has become apparent since this new set-up has settled-in, is that the extra power & current delivery, coupled with a much higher damping factor, have introduced a lot more control - particularly in the lower registers and this, in turn, has removed some vague veiling in the mid-to-upper registers.

I realise that the D700's and the Turnberry's are different designs, but these very differences should provide some guidelines:

The D700's had a rather reactive load characteristic with an overall impedance of 6 ohms but with a serious dip down to around 3 ohms at ~150 Hz. With a sensitivity of 93 dB, high sound levels were never a problem, although, at these high levels, the sound was a bit congested.

Given the differences between the D700 & the Turnberry:

Sensitivity: Identical at 93dB
Impedance: 8 ohms (Turnberry) vs 6 ohms (D700)
Drive Units: One 10" paper-coned DC (Turnberry) vs One 10" poly-coned DC PLUS a 10" poly-coned woofer

The higher impedance of the Turnberry should result in a more benign amplifier load.

I don't know what differences, if any, there are between the CP-50 and CP-35, or between the CA-100 and CA-101.

While all this is very theoretical, you may want to try to convince the Tannoy dealer to allow a home trial for final decision-making.
