You have the best sayings Ralph, zombie thread, expectation bias ect you should write a book on sayings. At first I thought you meant they were all zombies and can’t read graphs. Now I see that the thread is 2008 old, then my post is directed just at the last poster. Cheers George |
‘I’m not dead yet!’ This thread still has some life in it!
It’s now 2024 and I am asking nearly the same question… What tube amp(s) are recommended for Watt Puppy 7. I am currently considering a pair of Quicksilver V4 but I am concerned if they will have enough guts to produce tight / voluminous bass. |
@jdeitch i don't know if this helps, but about 300 years ago, i heard the audio research ref 600s with some watt puppies (maybe the fives). the sound was immense and impressive. |
The Watt/Puppy has an impedance dip at about 2KHz. This is there to absorb energy since there is a 2KHz resonance in the tweeter. This is why the speaker had a reputation for brightness with solid state amps, because solid state amps will try to make more power into lower impedances. A lot of tube amps will make less power into that 2 Ohm dip. In that way the tweeter behaves with them. Since most of our OTLs didn't make power into 2 Ohms, this worked exceptionally well with them and is likely part of the reason why the National Sales manager used them back when they were being made. In every other regard the speaker is easy to drive- our local dealer used our M-60 OTLs to demo the speaker. The M-60 makes 60 Watts into 8 Ohms so that gives you an idea of the power needed. If using a conventional transformer-coupled tube amp try the 8 Ohm tap first. This will help prevent the 2KHz brightness. |
