SET amplifier recommendation
I have been listening push-pull tube amp for a long time. Finally I'd like to try SET. Seems a lot of people moving from push-pull to SET. My budget is <$3000. Looking at Coincident Dynamo MK III 300B. As there is no dealer for Coincident, i can not try it/hear it. Anyone has this? I'd like to hear your comments. i also looked at Decware, Bottlehead, etc. It seems Dynamo is better. Line Magnetic has some interesting ones. But i am not sure the quality can match Canadian made one.
My main speaker is B&W 805. Listening space is less than 400 sq ft. My current push-pull setup is CJ premier 15+CJ premier 17ls2+ Audio Research VT100 MKI. Thank you.

Thank you for all comments. I also have some concern about sensitivity of 805. I do ask Israel regarding the sensitivity (both B&W 805 and Polk Audio LSi7). His answer is OK. if the speaker is an issue, i need a pair of high sensitivity ones. Is vintage Klipsch a good option? i heard they are highly colored speaker. But the sensitivity is very high. How different is the sound between 300b and 805 (LM 508AI, etc)? |
https://www.audiogon.com/listings/lis9g44j-zu-audio-soul-superfly-full-range I would rather recommend Zu Audio speaker with small footprint. Height: 38” [96.5cm] Footprint: 12-9/64”square [30.8cm square] Weight: 54 pounds [24kg] Bandwidth: 30 – 25kHz Efficiency: 101 dB-SPL 1W, 1m Impedance: 16 ohm Power Amp Range: 2 – 300 watt You can drive above with 300B SET to enough volume. But you may get nice sound with your current PP amp. |
With SETs, the bigger the amp the less bandwidth. 300b is about as powerful as an SET can get and still be considered ’hifi’ as far as bandwidth goes.That’s an interesting point, Ralph, which I presume derives mainly from the bandwidth limitations imposed by output transformers when they are used in SET configurations. Would the bandwidth limitations you refer to apply to the small signal bandwidth as well as to the bandwidth at or near full power? Or just to the latter? Thanks. Best regards, -- Al |
