Can tube amps play loudly?

Hello Gentlemen,

I'm in process of upgrading my current system. It's all junk...Onkyo receiver, Wharfedale speakers, etc. I've finally finished grad school and have decided it's high-time to upgrade to a quality two-channel system.

I've heard tube amps in various settings and love the way they sound. I'm strongly considering starting with one of the modified Cayins on the market (Bizzy Bee or PrimaLuna versions).

I’ll preface my question by noting that I am a total tube “newbie,” and I’m sure my question will speak volumes about my relative youthfulness. Here goes: Can tube amplifiers in this modest price range play loudly?

I realize this is dependent on the speakers and their sensitivities. What I'm looking for here is a relative ballpark estimate. There are so many good speakers on the market that I don't even know what to start looking at seriously. If I could weed some out based on their sensitivities, that would help me out a lot.

So, does anyone have any rough decibel ratings for tube amps similar to the Cayin? If so, what sensitivity are your speakers? I do realize that decibel ratings vary widely depending on amp power, speaker type, distance, etc. All I want is a rough estimate.

Any thoughts from anyone would be appreciated. I’d like to be able to narrow down my speaker choices before I start shopping seriously, because I don’t want to waste my time or a dealer’s. Plus, I’d like to know whether I can even achieve respectable volumes with tube amps on my modest budget.

Thanks!

Cds9000, I have used the Cayin with Klipsch RB-5IIs, B&W 602.3s, Morel 403.5s, and I in-home demoed the Meadowlark Eagles. The Klipsches sounded the best. I put that in the past tense because 3 nights ago my long-awaited GMA Callistos arrived...and my year-long speaker search is DONE! I will post about the Callistos soon, but, for now, let's just say that they excel at both voicing individual instruments and maintaining engaging rhythm. They also cover the bottom end better than any speaker with a 6" woofer has a right to. Roy J. sure did his homework for this speaker. Anyway, I listen to a wide assortment of music -- am spinning Ahmad Jamal as we speak, just had Beethoven's Violin Concerto on, before that was spinning Indigo Girls, Dakota Staton, Paul Simon, various modern woodwind quintets, the Beatles, Santana, Miles and Monk at Newport. No hiphop, no trance, no techno though. Given your budget, I have to say that the Cayin and the Callistos deserve a serious listen. Good luck. Enjoy the search.

Maxxc,
Many volume controls advance in 3 dB steps in their lower range and taper to 1.5 dB steps in the middle. A 3dB increase in sound pressure requires twice as much power. A 10dB increase is twice as loud. So in your example, a 96dB speaker is the one that will play twice as loud as an 86 dB one.

Audio Research makes (made) a good integrated with remote control which you should be able to find used for your price without a problem. It's a damn good match with ProAc Response series speakers which, if you're real lucky, you might find a pair of 2.5s for $2,000.00. I once heard a Manley Stingray integrated sound nice with Coincident floor standing speakers.

But to answer your question (even though most everyone else already did), yes - you can find a tube integrated which will play your speakers as loud as you want. I've been doing same for 20 years. Actually had a Mesa Baron which in pentode (although a bit sterile sounding) will blast music and can "rock a party". However, with the right speakers they can do this in triode for a much smoother, more natural sound. The Baron can be listened to in full pentode, 2/3pent-1/3tri, 1/3pent-2/3tri or full triode. They are actually two mono amps on one chassis but you'll need a pre-amp (or even a used Creek remote volume control for $150.00 if damn nice).

if you match a SS poweramp to a Tube preamp,make sure the preamp is capable of delivering the low end you want to the poweramp or youll be amplifieng soft bass,

Hi Rockvirgo. No thats not exactly what I meant.

Yes a speaker that plays at 86bd with 1 watt will require 2 watts to play at 89db and 4 watts to play at 92db. This of course does not take impedance and other factors into consideration and is a genaral rule.

No the 96db speaker is not playing twice as loud as the 86db speaker. 89db is actually twice as loud as 86db. But the human ear does not generally perceive a doubling in volume until around 10db although it is actually playing much louder then the doubling in volume we perceive.

I don't really understand your reference to the differences in volume control
