Default Altec or Infinity which are the better Loudspeaker?

Hi, I have a conundrum and I need sum advice... (Sorry a bit of a story follows). I have two nice pairs of loudspeakers I purchased second hand about a year or so ago when I first discovered what stereo was. Call me a late bloomer, long time music fan, short time audiophile. Through reading forums and some personal encounters I purchased my first true 'old school' solid state amp and loudspeakers. They where called Infinity Quantum 3. Some repairs where done. I really liked the punchy sound i got through the 2 bridged Nads and JVC preamp I purchased with the system. I paid $600 for the lot and well I started to think maybe there could be better in the vintage field, because as good as the Quantums are there a bit muddy sounding. So the search began. I did sum more reading and countless hours of sifting through classified sites and etc. Then 1 day I came across a very inconspicuous add without a picture sitting amongst the jumble of other classified. The guy on the add didn't have a price listed only a name 808-8g altec lansing and sum old records. So I researched some more and well came up with very little. I gave him a call becuase people all over the net seemed to think old altecs are awsome and well nothing ventured nothing gained. I lined it up to buy them, the price was steep $1200. After taking off the back of the cabinets i dicovered they where infact a pair of 604e's I paid the money and got em home. I later brought a Naim nap90 and Nac 92 to drive both. Ok so we come to now. The problem I am having is I love the punch of the Infinity's the music flows through you. But the clarity of the Altecs is amazing. Which in anyone's opinion are worth keeping cause I wanna get rid of 1 pair. I don't wanna rush into it and regret it later I think there might be a way to improve the infinity's sound but at the moment im leaning toward the altecs. Any advice ppl???

Don't rush into getting rid of anything, I was in a similar predicament 4 years ago, when I found some old jbl speakers on the side of the road. I took them home and put them in my garrage.
After 6months I had a look at them and decided to throw them out because they had some weird passive crossover adjustment, and I thought if they don't know how to design a proper crossover they must be crap, after all, the original owner threw them out.
Recently, I discovered what it was that I had stupidly thrown out
I am not going to say what I had because I still feel sick about it.

Thanks melonhead good advice. Wish I could run both at once but the power cost would kill me and probably the neighbours.

I on't know anything about the Infinity speakers but those Altec's are getting pretty rare to find like that. The crossovers that came with those drivers were not very great, just a common low quality xo of the time. You could improve the sound with some upgrades to the passive crossovers or even move up to active crossovers and two sets of amplifiers. I always liked the sound though I always thought that you do give up a bit in the mid-range between the cone and the horn. The bass could also be improved with better design of the enclosure matching specification to optimized cabinet and port size. Don't get rid of them until you hear all that they can be.

imo punchy has more of short term appeal and the clarity will be seductive for many years.

I'd love to find a pair of 604's of any stripe!

I've owned several sets of Infinity speakers from the Qe to the RS7 and, while I loved the sound, Altecs so far win the day for me

I would say own both for a while and let your heart guide you
