Yes, I know what the blurb says, but many people have been very impressed with the performance of them, myself included. Don Garber also offered them as a cost saving option in his 2A3 amp and said he was impressed with the bang for the buck you get with them.
Besides, how many of us are really running opts that go 20 to 20? Not very many I will bet, considering the extra cost. It's that last 5% again that can cost you big bucks.
Follow Ups:
Very few gapped SE transformers will go flat to 20Hz because it's hard to get the necessary inductance without introducing a lot of capacitance that causes losses of the high frequencies.
Having said that, the "big buck" transformers get very close to 20Hz and extend well beyond 20kHz.
There are a lot of things that factor into what a system ultimately sounds like but I have always believed that the best output transformers, together with circuits that are built as broad band and distortion free as possible results in really good sound.

Can't argue with that, but it leaves one thing out. How close to perfect do you want to get, and how much are willing to spend to get there?
I suppose for some people money is no object, but for the rest of us there will always be trade offs. Each of us has to determine for themselves what those will be.
It's not a philosophical issue. The Hammond transformers you're using fall short of hi-fi performance. Reasonable cost alternatives are available from Hammond, Edcor and Triode Electronics. Used transformers by HK, Scott and Fisher also show up occasionally on eBay. Full range OPTs will make a significant contribution to the sound of your amps.

Buy Chinese. Bury freedom.
It is a philosophical issue in that we all have our own opinion of what "reasonable" is and what sounds good to us and how much we want to spend.
There is no such thing as perfection with audio electronics.
Even with the best parts it's always a series of compromises, as is life.
