want another amp - which?

[donmarrese]

I've had loads of quad gear in my time, as much as I like the look of them, as well as their pedigree.. the quality of sound is not on pick on a properly serviced / upgraded AI S500, (a la DC) or a Lentek.
They both impress every time!

I beg to differ slightly on the A1 question, yes many have issues as they get old due to the heat and the use of lower temp spec capacitors (to save money presumably).

BUT the more powerful A100 sounds lovely and is worth the risk of some hassle IMHO. It has a taller case and a fan so it might be more reliable. I had an unserviced example for many years and it has no issues until the fan started making a slight knocking noise.

If you can find one serviced (including having the caps replaced with 105 degC ones and maybe a clean of the fan), or are willing to get it done yourself, then quite honestly you're in hifi heaven. Tim deP made a really good design with this one.

How does a leak stereo 20 compare to an audio innovations 500/700/800?

An AI500 is better, and it's no contest with an upgraded 700/800
