Amp and Pre-Amp suggestions needed

@ audionoobie
The HHR TLS-1 mfr suggests 400 watts rms which suggests you need considerable power to run these speakers.

At $5k, getting an integrated amp rather than separates is likely better price/performance alternative unless you plan to swap out the pre /or amp in the future.

Tone controls are usually frowned upon audiophiles who believe preserving the audio signal through the audio chain is the upmost importance.  Adding tone controls adds another layer into the audio chain which would likely degrade the sound which is audible in highly resolving audio systems.  On the other hand for some it's worth the sonic tradeoff (if any depending on the to resolution of the system and the quality of the execution of the tone controls) adjust the treble/bass to suit your tastes - different strokes....  

From what I read the  Parasound option sounds like a winner to me. 

Quick update: A local audio retailer that I have a relationship with has agreed to let me borrow a Parasound A21+ power amp and the $1600 pre, I don't recall what the name of it is off hand. He also mentioned another popular option was to have the Parasound power amp paired with a Rogue tube pre. 

If I like I will purchase both from him. 

Thank you all for the great suggestions and discussion. Much appreciated.

The Don Sachs preamp lists at $2500.   It is just a dressed up VTA SP-14, which admittedly comes in a very plain package at $1500 assembled, or $1100 kit.    It will make you smile.

As for a SS amp, I'd look for a classic Sumo Andromeda.  A truly great amp, but a little hard to find.  Well worth the trouble and can be typically had for $1000 or a bit less.   There's a used one on EBay that needs repair that can be had for cheap.  If you've got a good repair tech in your area, that's what I'd do.

But hey.  I love great audio for cheap.  This forum probably isn't the right place for me.

OK audionoobie,
you've got a 6Ω speaker that's 88db efficient, can be driven with 100w-400w of power, & the Rogue is not cutting it with these speakers.

The Cronus is already a pretty fair piece of gear, so don't make the mistake of a laterial move. $5G for a separate pre-amp and amp in the world of new gear maynot get ya leaps & bounds better than the Rogue if you're not careful.
Might I suggest an Ampex 402 pre-amp (see youtube attachment), pair it up with a Krell KSA 300s.

Ampex use to build tube powered recording studios, microphone pre-amps, mixing boads, tape machines, the works. They also made Hi-Fi pre-amps, with outstanding phono-stages. I use to own one, put my Conrad Johnson PV11 to shame and gave my snob Audion 2box Premier an inordinate run for the money. An Ampex 402 can be found for just south of a $grand.

Compliment the lush tubes of the Ampex with the lightning fast Krell. The 300 KSAs is pure Class A power. It's able to grab those 88 db Ohms by the scruf of the neck, & still have enough head room to sustain any crescendo thrown at it. A Krell KSA300s can be had for $3500 bucks.
