Lots of interesting suggestions. Few points worth mentioning:
1. I already have a Naim NAC 52 preamp. So adding a NAP 300 would not be an issue from the matching stand point.
2. Bombaywalla, thanks for your suggestions. Somewhere within, I know a high powered is always desirable for this speaker. But I am at a stage where I am unable to find an amp with a good balance of quality - quantity - cost. The tube vs SS battle is also on. After listening to the Wavac for the past few months, I am getting too critical of less than stellar sound from an SS amp. But then finding a neutral, high-resolution tube amp isnt easy either.
3. Charles1dad, you are really fortunate to own a 14ohm speaker. That is a cake walk for these 300B SETs. I auditioned the Wavac on a pair of WHT speakers which were 11ohms nominal impedance. The wavac could drive it to rock concert levels. So, in a way you are pampered :-).
4. Islandman, your suggestion of changing the speaker has already been on my mind since last couple of months. I have been weighing all options. After a lot of research and introspection I came down to this:
The Wavac remains among the most accurate sounding amps I have ever heard. Near flawless, I would say. However it is like a tool, a very high precision one. Tannoy prestige speakers on the other hand are a work of art. They might have flaws but to me they remain one of the most satisfying/fulfilling speakers to listen to music on. Since the time I acquired it I stopped bothering about better speakers! I mean even when I hear a better speaker I do not care because this Tannoy doesnt let me worry. When I auditioned it, it was being driven by $1k chinese amp and even with that I was floored. This speaker remains the best purchase of all time in my audio journey. I just do not know what to replace this speaker with (except the higher Tannoys). Till that time I will keep it.
The problem at hand is to maximize the sound for the money. I have written to Reno hifi for the F5, lets see if I could get a demo. I am at Singapore btw, so the typical demo policy probably wont hold for me.
