Lush and Romantic Tube Amps

Hi All -

I am on a quest for a lush, warm and romantic tube amp. Ideally, it should be 75 watts and upwards. I’m in a large room and my speakers are 87.5 sensitivity and 8 ohm. The room is large. 

The system:

LTA preamp 

Innuous Zenith music server 

Merason Dac 1 

Cardas Clear cables 


Suggestions are welcomed. 


Speakers seem to require lots of power. I would go with a more powerful tube amplifier especially if you've got a bigger room.

Just to clarify a little more what I started out trying to say above, what I should have asked is what warm and lush amps have you heard that you’re trying to replicate?Assuming you didn’t like the CJ sound you mentioned in your other thread doesn’t necessarily mean you will like warm and lush.  There is lots of middle ground.

To atmasphere:    Knowing your background of tube design, etc., would you recommend perhaps using a SS power amp with a tube preamplifier?  Or perhaps a ss / tube hybrid integrated?  Thanks.

@gregjacob If the speakers are low efficiency as the speakers of the OP, perhaps yes if the amplifier used isn't harsh.

'Warm and lush' is a sign of a prodigious 2nd harmonic. Our ears interpret the 2nd and 3rd as 'warmth' and these harmonics can mask the presence of higher ordered harmonics (5th and above) which the ear interprets as brightness and harshness (typical solid state attributes).

There are class D amps that don't make the higher ordered harmonics like traditional solid state amps do, and so sound very much like a very good tube amplifier. Driven by a tube preamp, such class D amps can be extremely life-like and satisfying.


Thanks for the answer.  I've looked at your Atmasphere Class D. It looks nice.  I would probably be looking for a single unit Class D stereo to pair with a nice tube preamp.  Have you ever considered making one? 60-100 watts... would be such a nice fit to reach for the best of both worlds!

Can anyone provide a working definition of "neutral?"  In other words, a point from which we can agree is indeed sonically neutral?
