Esoteric A-100 vs a03

Friends,
I am currently using a Wavac 300B amplifier with my Tannoy turnberry SE speakers. While I am enjoying the luxurious Wavac ride but there are always times that I feel the 10 watts Wavac is not enough. Especially while listening to Rock and pop music when I would like to crank it up and have fun, the music doesnt sound very comfortable. I know I should not be doing this with a 300B tube amp but then I listen to all kinds of music and I dont own a 100db sensitive speaker.

The choice is now either to go with a powerful push-pull which has the overall purity of an SET or a more drastic step towards a good solid state amplifier. I have heard the Esoteric a03 and liked it a lot driving a pair of Maggies. But I have never heard the A-100. Esoteric says that A-100 sounds as pure and neutral as master tapes, thats a serious claim, but then they are manufacturers. Can anyone here give me an idea of which of these amps would be a better buy for sonic purity, neutrality and dynamics ?

How big is your listening room and how loud (in dBs) are you trying to comfortably achieve?

Onhwy61, my room size is pretty small, about 170 sqft with a usual 10ft ceiling height.

Pani,
Needless to say that my opinions are strictly based on personal
encountersand everyone's experience is unique. Prior to using my SET
amp I used a custom built PP amplifier (Response Audio Bella Extreme V
cap version) by Bill Baker (Purity Audio).This is a100 watt/60 watt triode
with 6550 or KT88. This and a friend's VAC Phi 300.1 were the best
sounding PP I've listened to compared to ARC, VTL, Quicksilver, Rogue etc.

What I came to realize is that regardless of the PP amplifier they just didn't
have the "thereness" presence or ultimate realism I get
convincingly with a proper SET -speaker match. In my case it was an easy
and in all probability permanent change. Of course your outcome may be
different from mine. I really enjoyed my Bella Exreeme PP amplifier until I
got the Frankenstein amplifier and directly compared them.

Based upon your comments I imagine you will be happier sticking with tube amps. Coincident, Atmasphere and David Berning all make not too expensive tube amps that can provide you with roughly 6dB more headroom. As a less costly alternative you might consider the Van Alstine Ultravalve 70. Keep us updated.

Yes,
For these particular speakers an 845 SET or good PP amplifier may be what you need to satisfy your objective.

Pani,

I have an Ayon Triton 1 integrated amp and like it a lot. It's 125WPC pentode, 80WPC triode; Class A operation with no negative feedback. Uses KT88 tubes. If that sounds like enough power for you there's one listed now but with about 18 hours left in the sale. You might consider it.
