Winggo, much more important than your speakerss sensitivity is its impedance. If you have low efficiency speakers with a benign impedance, you can solve any power issue by adding more tube power. If your speakers have either too low or too demanding of an impedance curve, then tubes are not recommendable, regardless of power. http://www.enjoythemusic.com/magazine/bas/0808/ |
I personally do not like the sound of most high-powered pentode and tetrode tube amps. Many sound much more brittle and dry than good solid state amps. Notable exceptions to me are some OTL amps. Most solid state amps these days do not sound grainy, brittle or thin to me--common descriptions given to tube sound in the past. Where they are often lacking is in dynamics at lower volume--compared to a good low-powered triode tube amp they sound lifeless and lacking in immediacy. There can also be a "mechanical" quality to the sound that comes from a slight artificial edge to the attack on all notes and a lack of the subtle variation in attack and decay of notes that one hears with better tube gear. With suitably efficient speakers, I prefer low-powered tube gear. For speakers needing more power, I like OTL tube amps, followed by solid state and then followed by high-powered tube gear. |
Agree with Phaelon, the speaker's load characteristics(impedance curve-fluctuations and phase angles) will determine if tube or transistor amplifier is the best option. Along with Isochronism and Larryi I much prefer the lower power amp with high efficiency speakers route for the same reasons they cited. Regards, |
The best amp is the one which is most synergestic tube or SS. I prefer tubes but one system I have sounds best with SS. I have tubes in other systems which are also magical. Try both tubes and SS. Carver and Manley, ASL Hurricanes are all good top fuel choices. Tubes will seem cheap to a transistor replacement and they do have a lifespan. A friend had his Krell mda 300s repaired...3k. 3k buys a lot of tubes, no free lunches. I prefer high efficency speakers. Pick your poison..... Jallen |
