76.111.198.182
my little Chinese stole the show. I finally got around to trying the 300Bs on the Tannoys on Monday. I made the usual rough hookup as you can see, the mono blocs played those big boys to good levels from top to bottom.
I didn't play any hard rock music, I stuck to jazz. The bass was pretty good, but I did not feel as comfortable driving them as hard as with the solid state.
However, what really amazes me is my little Dared MP-7 SET amp from the office system. I decided to try it on the Tannoys today to see how it would do, with its 6 watts output from new JJ 6L6gc I installed a few months ago.
Well let me tell you, it just filled the room with music, not as dymanic and deep as the 300Bs but the midrange and top end sounds so relaxed and sweet, so smooth and refined, I could not stop listening.
I played mostly Miles Davis on vinyl and it was to die for. This was with basic crappy cables, with the mid-fi HT vinyl source. A vintage Kenwood KD750 direct drive with a Elac cartridge, feeding a AES PH1 phono stage built from kit. That little amp certainly has some finesse that the 300Bs don't have and these Tannoys certainly shows it up.
I think I have some work to do, my speaker journey may have ended, but the amp journey continues.

Sure. Without looking at the specs, I'd guess that the little Dared MP-7 is more likely a SEP running -ve feedback. The benefit is that this likely provides a lower output impedance (than a zero NFB 300B run at typical operating points), which is what the Tannoys need.Personally, a typical 300B is not ideal for Tannoys. Keep those true SET amps for low Q speakers systems that need minimal assistance to keep them under control.
Cheers.

I don't know if perfection can ever be obtained but your answer is close.
Jota will go toe-to-toe with most anything.
Yes, they might work better than more typical SET amps, but they would perform better when ideally matched to speakers of suitable Q (and other prameters).
That said, there is pleanty one can do to design a SET that is more universally applicable, but there are sonic tradeoffs and you still can't fully avoid matching issues.
Cheers.

A few more watts, more current, and so more control of the bass driver and more headroom. They are expensive, but will end your search for 300B amps.
Next would be MasterSound 300b.
Wow, interesting! Maybe try both the Dared and 300B amps for a while ... hmmm ... can the Tannoys be bi-amplified? Might be too much to think about ...!
Too much is right, they could be, but I would probably need a electronic crossover. That just gets too complicated.
AB.
yep, certainly (for best use) need an external crossover or at least filtering on the inputs to the amps. Maybe one of the other amps suggested would be 'just the ticket' (likely an expensive one tho!).
I just got home from picking up my Decware Zen Torii Mk III amp at the factory in Peoria. Everyone above is right... 300B's doubled up do provide good results, but the increased cost is significant. Please read about the Torii on the Decware site, and how it specifically is designed to provide the clarity of 300B's through EL34's with the Hazen circuitry mod - 25 wpc!
I ordered mine the last week of January and it was finished in late May. I arranged local pickup and when I arrived it was on and warmed up. Steve said that it had about 25 hours on it, and it sounded quite good there for an hour. I have been listening for 2 1/2 hrs through my Canterburys and it is amazing! More time will result in better sound but it is already exhibiting more depth and power, at slightly under $3000. (Freight to Omaha would have added $62)
The amp is guaranteed for life and if it does not float your boat you can
easily sell it to someone who does not want to wait... Mine will not be for sale until it's in my estate! Thanks for reading.
