Amp advice sought for Coincident Total Victory


I had driven my Coincident Total Victory II's with 100 W el34's. Now It's a 12 W 300b. I like the tonal accuracy and low level detail much more but do miss two things about the higher powered amp. One is the ability to occasionally turn it up. The other is the headroom needed to to accurately reproduce the fast rise of, for example, a piano or drum. For me, the TV II's are just below the efficiency needed for 300b amplification. Does anyone have experience with a sub $4k used tube amp or amplifier topology that would be a good compromise?

Thanks in advance,

Dave

Something`s strange here.Your speakers are quite simillar to mine(Coincident Total Eclipse 94 db)but even more sensitive at 97db, and with 14 ohm load. I get drsmatic speed,dynamics and jump factor galore with the 8 watt Coincident Frenkenstein 300b mono blocks. Others on this site report the same with this amp drving the Total Victory4,super Victory and the Pure Reference speaker. Though your amp is rated at 12 watts it may lack the driving capacity due to perhaps lesser power supply,driver tube or transformers. your speakers absolutely sing with effortless dynamics and control when mated to the Frankenstein(very stiff PS,large custom transfomers and 6em7 driver tube). Have you ever considered this amp? I used a very good push-pull amp(100 wattpentode/ 60 watt triode) and with this speakers the Frankenstein is better without question.Power supply and transformers are so critical when it comes to driving speakers sucessfully.
Rfogel8,I was present at that session and to be honest the Frankenstein MK2 amp was more transparent,open and dynamic than the Atma-sphere. The other listner present FWIW felt the Frankenstein better, it`s all subjective. And yes multi driver speakers can be driven quite well if designed with the intend to mate with low power SET amps.It`s in correct to equate fewer drivers with= easier load it`s not that simplistic.

One point to keep in mind is that Israel Bloom used your speaker(mine also) heavily for the design and circuit of the Frankenstein MK2.He`s adamant that it will easily drive any Coincident speaker he has built.The fact is all 300b amps are`nt equal, they range all over the map. As Azaud mentioned above the 6em7 driver tube is ultra high current and requires it`s own PS seperate transformer.It`s very extended and powerful as per design. I hope you`ll get the chance to hear one and judge for your self. The Cary may have different design parameters.
Mmike84,
I agree Israel is quite approachable and refreshing candid. Dave See if you could arrange an in home audition.I`d hate to see you judge 300b amps based on your Cary. As a number of posters have stated the Frankenstein amp is of a diefferent caliber.I don`t believe the issue is simply more watts(you`re using less than 1 watt at most listening levels most often) but probably higher quality.

Like you I own the Total Eclipse II speakers and they are brilliant with the Frankenstein. You raise an interesting point. The T.E. has 2 10 inch woofers and the T.V.II uses 4 8 inch woofers, I had`nt thought that a major difference but it`s certainly possible. There`s such a variety of personal accounts and opinions with the many posts here. Arthur Salvatore says a 5 watt amp drove the T.V.II well, yet you preferred more power with your encounter. Perhaps the T.E. though 3db less sensitive is easier driven with low watt amps. I do prefer the Franks over my 100 watt push pull amp. Horses for courses I guess.
Hi,
PMB,who knows which is better, what`s obvious is that you`re very pleased with the Manley amp and it`s providing you much happiness.I`m curious about the transformers in your amp.I always thought SET transformers were different from those used in a PP amplifier.Continue to enjoy.
Dave,
For the sake of followup after such an interesting thread, what amp did you decide to go with?
