Summary:
I¡¦ve been hearing Quad for more then 10 years. 34+306 to 44+405 to 66+606 to 77+707. I think 707 is not only the upgraded model of 606 but also the sound and the look, it¡¦s all-different from the old quad. It¡¦s a brand new sound. The new quad solves the weakness problem of pre-amp---a little byte harsh. And the weakness of power amp----a little byte slow.
707 is more honest, powerful, detail and fast. The most important thing is 707 must marry 77. And must with quadlink unless you link with other cost 600.
77+707 is wonderful for me.

Believe your ears.

***The rating is for 707

Summary:
Great Amplifier. Gives more body to ESL-63 than the 306. You forget that you own them. They provide you with Music. And for that matter also okay for Surround Sets (Together with a 306 for the back-speakers it is a RatPack)
Maybe not as trendy as other Amplifiers, but these Amp will stand for many years to come, just like the 306 and the 303.
(I have to modify my 405 still)
Bit tricky with B&W speakers: Small and Big ones don't give the stability that KEF seems to have with a QUAD combo.
I tried several B&W speakers and none was as good sounding as most KEF speakers. (Even the old 104/2!)
With the ESL-63 great combination for Classical & Jazz. Voices cannot get better.

Strengths:
Same sound as 306. Not spectacular. Great Sound, Lots of Power.

Weaknesses:
Connectibility to HighPowered PreAmps. (Any Quad is okay)
B&W speakers are not advised.

Summary:
I was perfectly happy with my Power Amp (a self built amp from the Elektuur) until its temperature stability got out of control. I decided to look around for a good replacement with a solid company and service organization behind it.

I am one of those people whose dad already owned Quad equipment so I was tempted to buy one as well.

When I found my 606 for a good price I checked with the distributor for the Benelux. These people provide a superb service, they don't try to sell you the latest model but they gave me all the information I wanted and more than that. Thumbs up for Transtec in Rotterdam.

I then decided to buy it but I didn't expect the sound quality to be better than my old amp, I just though to have an similar quality amp but with less hassle.

Well was I wrong ! When I hooked it up to my Luxman pre-amp and my B&W speakers the whole set just came to life. Deep solid bass, crystal clear highs. The transparency that comes from this machine just took my whole set to a new level. Just when I thought I had to upgrade my speakers the 606 showed me that there's more in them than I knew.

Conclusion : Very good, worry-free, hi quality amplifier. Excellent distributor channel.

Strengths:
Simple, solid, excellent support

Weaknesses:

Well made, good powerfull sound and matches well with quad 34 and CD 66 player. Sound is the same as Quad 306 but with more grunt. Internal quality was dust free and like new.

Inherited a 606 made in 1988 and a FM4 made in 1985 both in mint condition. The quality of build is first class so is the sound.
