An Endless Journey.


I've been pursuing, listening, looking, toying, buying, selling 2 speakers stereo system since I was 11-12yrs old as my hobby. It's an endless journey with a lot lot enjoyments. Bottomless money-pit as well, I would said.
Then when I was 34, tired, broke and still no satisfaction, no end on the sight, I bought a Rega Planar 3, a Rotel RCD-855, a Naim Nait 1, a Rega Ela and I called it quit.
So happy I am for the next 30yrs, so much I enjoy the Music, the Instruments, the Soundstage, Clarity and whatever comes out from the system.
Now the Rega Ela lost their Tweeters. 
Should I spend $2-300 and find the Replacement  or just get rid of them?
Note: I still enjoy and love the sound of Rega Ela very much.

Does an 80ish speakers as Rega Ela stands the chance to compete with any speaker now days? 
Of course they both are very much in the same  Pricewise.
Rega was $1250 back in 80ish, probably would be around $1500-$1750 now?
Should I start my journey again, it itches inside out.
Get a pair of Quad 57's! They will work well with your Naim  Nait amp. Every audiophile should at some point own a pair or two!
90 db efficiency is +/- this or that, pretty efficient, at least not inefficient.

I might try to go less power, more affordable choices, even tubes, and pick an amp that can be used both Stereo now and as a mono-block to add power in the future if desired.
Check with Madisound to see if they have suitable replacement tweeters.

I think something like this might work...

But, best to check with them.

The original Rega tweeters were custom from Scanspeak which is not to say that Scanspeak did not eventually incorporate some of the design changes into a standard model.

Samadhana, a lot more than $1500. Try $4000. Unless you are game for a total rebuild without any assurance of what they will sound like in the end I think you are best served with a new set. They served you well.
The Tweeter is a Scan Speak unit, the woofer I am not sure about. It is a transmission line enclosure which effectively doubles the size of the woofer. So, you are looking essentially at a two way speaker with a 12" woofer. Transmission line speakers are rare. They are difficult to design and expensive to built. The only one available now that I know of is the Sander's Model 10 which is not going to be your cup of tea. 
I think you have a lot of listening to do!
