Bought some `Vintage Gear`

Roberjerman...do tell... Would like to read your experiences.

Similar experience here a couple of years ago picking up a late 70s Marantz DC170 amp.  Really lovely sound for cheap.

I bought a pair of L200s brand new in 1975 and had them for the next 25 years til I got my AG Duos. I sold them to a friend who lives close by and I still listen to them every week or so. At 45 years old they have never had a repair or failure and the veneer still looks exceptional. And they ROCK. Maggies are gonna sound awful wimpy and polite in comparison (and I have my doubts about your being able to integrate Maggies into the space the JBLs are occupying). And they WILL take power. I fried the output transistors on a Bryston 7BST (500 watts) whilst engaged in a rather spirited playback of the "1812" one evening long ago and the associated speaker just shrugged it off...no fuses blew...nothing. Without a doubt the most indestructable and least fussy audio product I have owned. Currently thriving in an all Atma-sphere system.

1. I had McIntosh MC30 from 50x. It exchanged Plinius 8200 in my system. No comparison  MC30 was other level of tone, natural organic sound and musicality. 30 watt McIntosh controlled bass and had bigger sound than 175 watt Plinius.
2.  Lenco L78 turntable exchanged Nottingham Analog Spacedeck.
Lenco has much better PRAT, bass. After that I will never go back to belt drive turntables. They make rhythm and pace messy and kill music, especially classical and jazz music with a fine rhythm sense. 
3. I bought Altec 604E speakers (from 60x) in 2005 and I have been using them until now. I had Spendor 2/3 that I liked. But Altecs are different league (even with original crossovers). The sound has volume, and body, it envelops a listener. Musical instruments have a real size, dynamic, tone.
4. I also have EMT948 turntable made around 1990. It exchanged Lenco in my system 8 years ago.

When I used a modern stuff I was changing everything very often. I bought and sold my audio gear every year and lost a lot of money.
Now I can enjoy vintage components for many years.

Very cool!
