Tenor OTL 75wi vs 175s


Folks,
I just bought a pair of Tenor OTL 75wi. I use it with a Lamm preamp. I do not know how exactly put it in words, this is the finest amplifier I have ever heard and that too by miles. It is unbelievably realistic sounding. The only little issue is, my Tannoy Turnberry SE seems to make this amp run out of gas for some kinds of music and at certain SPLs (not head banging SPLs). I cannot imagine letting go this amp. But I was wondering if it was worth saving up for the Tenor 175s which would give me all the headroom I would ever need but then the output stage is solid state and I do not know whether it can match up to the magic of all tube OTL 75. Has anyone heard the 175s and OTL 75 to give me an idea about how they compare ?

Changing the speaker is another option but I have kept it to the last because I absolutely love the Tannoys.

As Mike said .... the Tenor hybrid amps DO NOT have the magic of the OTL's. Find a speaker you like that your OTL can drive and enjoy. It really is a great amp!
Hi Mike,
So which other tube amps do you consider in the same league or better than the Tenor OTL 75 ?

Any speaker recommendations for a normal 200 sqft room which works well with the OTL 75 ?
Some obvious speaker recommendations are the Classic Audio Loudspeakers, also Audiokinesis. We've used both at shows with our OTLs of similar power to excellent effect!

Any speaker that is at least 8 ohms in the bass region (without dips below 6 ohms) and otherwise at least 93 db 1 watt/1 meter should do the job.

However looking at the specs of the speaker, it sounds to me like the amplifier has a malfunction- weak tubes, bad sockets, something like that. The speaker looks like it would be no problem for an OTL.
Hi Atmasphere,
Thanks for the suggestion. By weak tubes, are you indicating at the driver tubes or the output tubes ?

Secondly, do you have any recommendation on what kind of speaker cables should be used between a typical speaker and an OTL for a good match ? I currently use a 3 meter biwiring set of Auditorium23 speaker cables. Do you think shortening the speaker cable to less than 2 meters can actually improve the amp's response ?
