Amps Using the 211 Tube

I used to own a Cary 805AE SET amp. With this amp, you had a choice of using 845 or 211 output tubes. The 211's sounded more powerful, with better control of the bass. The 845's had a more full midrange, more airy top end, and had more of the SET magic. I vastly preferred the sound of the 845's.

Sidssp makes a valid and important point, and I would argue further that the "sound" of a tube is confined what the specific tube IN A SPECIFIC CIRCUIT (Topology, Transformer, Driver stage, coupling etc.) can/will deliver. The second point - to reiterate - is the 811 (and 805, 845, 300b, 2A3) is (are) triodes - that is they have three elements, Anode(Plate), Cathode(For many triodes, the cathode and filament are the same, or called: 'Direct Heated') and screen or grid. the 6L6 is a 'Beam Power Amplifier'-per the RCA manual - and is actually a tetrode, or four element tube with 2 screen/grids and an extension from the cathode to focus the beam. They are not the same beasts....

I come from Hong Kong, nowadays chinese factory had made many tube amp with very good quality. I have bought a new brand(Bewitch) 211 monoblock amp with the 211 tube operate at 1100V which is higher than the common used voltage 900V for 845. My experience is that the sound of 211 (1100V) is much better than that of 845 tube especially playing classical music, better separation, bigger sound stage, greater dynamic.

my opinion is 211 win 845 a lot
