Pairing Bryston 28b3 with tubes

[grandsoir]

Hello all

I have a pair of Bryston 28b3 monoblock on its way, which I want to pair up with a tube pre-amplifier.

I want to add that "tubemagic" to make the music come alive; emotions and toe-tapping and I´m interested in hearing from you guys what your experience have been.

What could be a great match with the monoblocs from Bryston.

These are some of the pre-amps I´ve been reading up on.

- Cortese from http://www.supratek.com.au/
- Microzotle from LTA https://www.lineartubeaudio.com/products/microzotl-preamplifier

The speakers I will have is custommade with these specs

Drivers: 4 x 17,4cm
Treble: 1 x 2,8cm
Impedance: 7 ohm
Effect: 800W
Maximum effect: >20 kW (> 400 hz)
Sensitivity: 92dB-2.83 V
Power handling: 5w (min) to 2000 W (max)
Soundpressure: >130 dB/pair, 100 Hz (1,4 kW)

Thanks

Just a word to the wise, whatever tube preamp you choose make sure it's happy with the Bryston's input impedance and the length of your pre-to-amps interconnects. Any competent dealer or manufacturer can help identify a potential mismatch

From Supratek's “Guide to Buying a Tube Preamp”
Going back to our example above of a simple triode preamp - it will have an output impedance (Z) of around 6K, so you wouldn't want to use it with a power amp with input Z of less than 50K .

HTH Enjoy the hunt!
