Hi Goyal,
Welcome to HFV.
For Tannoy you may call Sunny. He has his office in C.R.Park (3rd floor) just opposite to FX Entertainment showroom. He is a very good guy and friendly too. In his office he has a pair of wallmounted Tanny F1 pairing with Yamaha Ampli.
I have once got audition of Tanny F1 and Tanny Reveal 6 Studio monitor pairing with Lyrita valve amp in Viren's place. Sunny has a small spare room in his office, which has high volume Studio monitors. I think if you carry your amp, he will be kind enough to arrange an audition there. Or he may agree to send his speaker at your residence for a day for audition. He also stays at Noida. As somebody said, you may try Reveal 6 studio monitors also. It is a very good speaker (6.5" woofer and 1" tweeter) with high sensitivity 90 dB. It is back ported and need at least 1-1.5 ft distance from the rear wall. It has good high and midrange and decent bass also.
Happy hunting.
