Apart from, when you get even less..

Agreed 

But to be fair to the Proline,, despite the obvious shortcomings it's still a lot of amp for the money.

A couple of cheap mods could make it into a perfectly good amp, one that would put many much more expensive to shame. 


Fully agree.

My comment was regarding the Thomann TA2400, Ok amp on Mids, but would not use for sub.

The Proline 2700/3000, was a whole lot of amp for the money, back in the day.

Proper transformer, huge amount of output devices per channel, exceptional cooling/air flow strategy.

I mentioned years ago, I ran a 2700 in 4 ohm bridge all night, and when party was done, amp was cool to the touch.

Only problem with these amps, was the clip handling, which is why I always said, these are great bridge monsters, but who wants to walk around with 5.5 stones of amp, per pair of 18s.

Probably, those are all excellent amps, but if buying second hand the Proline would be cheaper. l guess in terms of mods it's fine if you can DIY but certainly not worth paying someone to do it, when you can pick up better amps for perhaps £100-£200 more. But the Proline is still a solid amp for the money.

 Here's a thought that's maybe or maybe not worth considering, just a random thought out of the blue have any of you very well educated guys ever thought of maybe contacting these cheap Chinese amp companies and asking if you can work with them to provide them with the knowledge of how to make their amps more reliable and witrh quality clip limiters?  

I'm not very well educated at all lol school dropout me LOL

The Chinese OEMs are often perfectly capable by themselves of producing good designs and good build quality. But they build down to a price point, so they have to cut a few corners to get there.

You have to bear in mind, those old school heavies like Crown Crest etc. were very expensive when new, perhaps 3 or 4 times the price of the Proline, and that's ignoring 15-20 years of inflation. Price wise it's like comparing a 20 year old Mercedes to a brand new Kia. But the Proline (and indeed some other Chinese amps) are actually a lot closer to Crown/Crest etc in build quality, than that car example. So in terms of value for money, they are not so bad.

I have had some Tamp 1400's,  no idea if the build quality is something like proline 3000 has but they were mostly medicore. Lots of soldering issues but great amps for the price (except for sub duty, great for kick/mid/highs). 

Anyway, its kind of nice that even today, some big iron amps are still manufactured. Mostly chinese things tho.. but as example QSC RMX 4050/5050 are very good.

Crown's last heavy w. amp was XLS 5000?

Tbh I have never actually seen the inside of a Proline for real Tongue

But from what I have seen/read online the assembly quality is ok/average. The basic drive, output & PSU design is quite similar to some of the classics, the main difference seems to be the components are speced much closer to the wind, whereas the old school heavies were usually massively overbuilt,120v caps for 80v etc. which is why they go on forever. Crest used to do a 24hr, 100% output burn in test, for every new amp built!

The Proline should  do the business, but not so sure how long it will last!

Agree with that, but also can't really knock that China has made many things more affordable for all. 

RMX are China manufacture too I think, but yes 4050/5050 has v good reputation. I guess that shows China can build quality too, when that's what's ordered.

No idea about last heavy Crown, TBH I'm a bit out of touch, I used to play with Crest/Amcron/C-audio/Hill/Citronic etc when they were new Wink
