Actually, my first hifi was almost-all Sony, and bought with almost-all ignorance too
. The amplifier was later "upgraded" to a [I think] Sherwood (after the event, I have doubts that that was such an "upgrade"). I was then shopping around for a new amp, and, one day, bought the demo speakers instead of the amp! That was my Castle speakers, which I still have. Nice, but I don't claim they are in your league, even though the list price, at that time, would be around Rs60,000 today.
I enjoyed my new speakers. I knew they were capable of better, and it was confirmed when I bought my Cyrus 3i, my real hifi
ahaa! moment, and, possibly my introduction to
real hifi. I decided that what I had been listening to before was
distortion!
The castles don't now, have the opportunity to show if they would show off even better source/amplification.
If, for instance, I had the opportunity to buy and use speakers like your Tannoys, I would gladly do so. It might be a mistake for poor equipment, but I think they would make anything from mid-level upwards sound good, whilst having plenty of capacity for showing off almost any upgrade.
But, whichever end of the chain a person decides to weight, doing so is just upgrade space in the rest. So long as one does not choose equipment that just plays badly together, really good equipment is to going to be a waste.
Much of this, I have to admit, I have not done in any planned way, but by buying as and when deals came my way. Half-price speakers, half-price amplifier, etc...
(By the way, my Sony amplifier and speakers were a lot better than one might think that name would imply these days! I actually wish I still had the amp for possible repair by Mr Sayeed, and had not given away the speakers before leaving London. They were more than good enough for a second system)
