Amp and Pre-Amp suggestions needed

Moving from 100 watts to 150 probably won't deliver what your after, i would think you'll want double or more your existing power. I think there are more integrateds with tone controls.

All McIntosh preamps have tone controls.  

I’m curious, what did Dale Harder recommend?
What’s the impedance load, phase angle, sensitivity, power handling capability of the speaker? What is your room like? Do you have preferred musical genres? What other gear sound signature do you like?

i listen very carefully to what speaker makers suggest and use to drive their products

they would know better than most and certainly have the greatest incentive to find out, among the ocean of possible choices

@mofojo  I am doing both analog and digital.

@jjss49  Can you tell me what is meant by line stage? I am not opposed to using the Schiit Loki as I have heard good things about it. 

@unsound Dale recommended a preamp like a Conrad Johnson PV-12 and the amp was an Antique Sound Lab Hurricane mono blocks.

As to the rest of your post, I really have no idea what impedance load and phase angle are. Their sensitivity is rated at 89db. Dale says the more power the better and that he has clients using 300 and 400 watts per channel.
 
My rooms are small like 13' x 11'. Preferred musical genres are Jazz, Pop, and Fusion.

A good friend of mine also has the TLS-1's and is using Vincent separates with great results. 

Any thoughts on how their gear stacks up to other similarly priced offerings?

Thanks all,
Joe
