Integrated Amplifier with the Good Bass and Extended Highs

Maybe an integrated with tone controls? You can tailor to your liking.

I heard the Hegel 360 at the Los Angeles Audio Show and it was very good; considerably better than the Rost although the Rost was pretty good. They performed comparison tests between the Rost, 360, and their reference separates. The 360 was fairly close to the separates and it and the Rost have built-in DACs. The demo speaker was the KEF Blade 2. I liked the Hegel sound.

The T+A has tone controls....Not well known, but well worth checking out... Here is the base model.... they compare it with the Hegel H300 & H360...

I noticed that dep14 posted Coda.... This is also very nice stuff.

As above,
both the Rega Elicit-R and Anthem 225 are very good for the money, indeed.  The Anthem has incredible current to drive any speaker easily.
Excellent sound from both amps.  Happy Listening!
