Power requirement is a function of a) sensitivity of the speakers, b) how loud you want to be able to listen to them on at least an occasional basis, and c) the need for some amount of "reserve" power (headroom) available to accommodate transient peaks and thereby avoid/minimize clipping distortion from the amp.

Those speakers have a relatively high sensitivity rating (they put out 93dB with one watt at 1 meter). That's what I would call quite loud. Assuming you gain 3db for the second speaker and then lose 8db to account for 8-10 foot listening distance, you'll be getting 88dB with one watt!

Unless you are trying to make your ears bleed, or playing them outdoors, I think a target of 94dB for maximum loudness should satisfy just about anybody's needs. Each 3dB of loudness requires a doubling of power, so to get from 88dB (one watt) to 96dB you'll need 4 watts.

A good rule of thumb for transient peaks is 9-12dB (altho they can certainly go higher!). So, to account for 9dB peaks, you would need an amp capable of putting out 32 watts. For 12dB, 64 watts.

So, if I were you I'd be looking for an amp with an RMS power rating of 60 watts or more. Your speakers are rated for 100 watts of nominal output (and can probably handle quite a bit more than that during quick peaks). And of course you can always have an amp capable of producing more power than your speakers can handle....just be prudent with the volume control!

There are lots of good integrated amps and power amps in the 60-100 watt range. Make sure that whatever you get is rated to handle 4 ohm speakers (even tho your speakers are 6 ohm), as this will give you some assurance of a somewhat more robust power supply.

Good luck with finding the right amp. As you narrow your choices, I'm sure the AK community can provide useful commentary regarding specific units that you are considering.

I just noticed in your profile that you are currently running a Sansui AU-517. From a power standpoint, that's a pretty good match for your speakers...and if it's in good condition, it should sound pretty nice as well. If I had put together a list of integrated amps to consider, I would have probably put the AU-517 on it! What are you trying to accomplish with a new amp?

I'm actually running an AU-717 now but i have it powering a pair of technics sb 660's (super rare), so i'm looking to run the 6000's on a power amp alongside the 660's using the 717's pre stage

 

[Guest105]

Well, if you still have the 517 it would make a good power amp for your 6000's. I'm guessing you no longer have it?

I'd put the money for a new amp toward a full restoration for the Sansui(s) you already have....and suggest you do the same.

 

[richersounds]

Sadly no
I did pick up a Carvin fet 400 today and an carver PM-350.
But the carver is going on ebay and the carvin is just fugly and untested yet. i need to pick up some cables for it tomorrow.
I doubt its going to stay even if it works though i want something that looks a little less pro that fits better with the Sansui

I certainly will be doing that at some point in the future!
Honestly though the Sansui sounds clear as a bell with the 660's so i won't be doing it just yet

I owned a Rotel RB-1050 for a while, and liked it quite a bit (70 watts/channel). Another vintage amp you might also consider is the Yamaha M45.

The problem with recommending a specific used amp is that the odds of finding that particular unit in the local used market are not good. Of course, if you are willing to use ebay (premium prices and shipping risk), you could probably find either one of them pretty quickly. AK Bartertown is a relatively safe alternative for finding good used gear.

I'm sure there are many, many, many other good choices in your price range...just thought I would mention two with which I have personal familiarity.

Kenwood Basic M1,M1A and M1D are in your price range and will drive those speakers fine. They are 105-125 wpc

Theres a Hafler dh 200 for 100$ available in my area, worth going for?

Yes, I had one and I think it was one of the best sounding amps I ever owned.
Lots of mods available too if you are into that.
