Pre + Amplifier Recommendation

Hello All,

First let me say I have spent countless hours researching what may or may not be the right combo for me and my listening preferences - the reality is that there are so many options I am likely more confused now than before, though not from a lack of effort.

So, I have Dali Helicon 400's and listen primarily to rock / folk indie primarily, but do listen to most genres. I have a Cary SLI-80 with upgraded tubes and it sounds great, but lacks a bit of power when i want to turn it up and i am wondering if in addition to increased power i could move up the food chain a bit and get something even better, so long as better is not in the five digits.

I prefer tube sound to any solid state I've owned or heard to date, and my primary concern is being engaged in the music not hearing every last detail, thought that is neat as well.

Was thinking maybe a set of used Cary 805AE units, but fear they may not have enough power. VAC ? BAT ? Quicksilver ? Coincident ?

Or should I start over with new speakers as well? Daedalus Argos look pretty cool and are seemingly more efficient, may open up the options on amplification?

Look forward to your suggestions and thanks in advance.

"Juggernaut850, keep in mind that the speaker/power relationship is not linear and works on a logarithmic scale. To achieve a 3db increase requires a double of amp power. So going from the 80w Cary to a different 100w tube amp will not solve the problem. That is an increase of less than 1db, and will have little to no effect on the underpowered problem."

For that to hold true in a real application, the amps would have to be built and measured exactly the same way. For example, 2 different 100 watt amps made by different companies will not put out the same amount of power. Also, there are other factors involved in volume than just doubling the power to get 3 db more.

Tls49,
+1. Depending on the speaker used, 1-10 watts is all you'd ever require. On the other hand there are speakers where 300 watts of power is inadequate under certain conditions. High current capability is sometimes more of a factor than the wattage of an amplifier. The speaker's design characteristics determine the appropriate matching amplifier.

Zd542, Not sure what you mean by this. Can you explain?

Other than room and listening distance, then what?

May be can try audio research ls17se + bryston 4bsst2 combo? This combo should get you tube sound with enough power for most speakers... Each item is under 5 figure. You can choose to upgrade in phases.
