Help. Wife says Teres 340 Is too bright.

Jj2468,
Regarding Silverline Audio speakers- I beg to differ. I owned Bolero, and it absolutely did need a lot of power to sound its best.
90 w/ch. of PP tube power was not enough. 150 wt/ch of triode power (BAT-150 SE) was significantly better.
I tried SET amp- was awful.
I have a suspicion, that many manufacturers are rather optimistic in their sensitivity claims.

Maril555,
I have not heard the Bolero. Have you heard the Sonata?

What SET amp did you pair with the Bolero?

Jj2468,
I have. And Bolero specs are very similar to Sonata- 92(or 93) Db and 8 Ohm.

Thanks to all for your input. Regarding loading, it is set at 42ohms. However this is done via cheap resistors installed in RCA plugs and inserted into a Y connector at the input of the tranny. FWIW, I have never been completely comfortable with this arrangement though it was suggested to me by someone who is pretty knowledgeable. I don't like the fact that it has so much wire run in the analog chain, which in itself may be causing the problem
Concerning the amp/speaker combo, I was not aware that one could have too much power. I have been wanting to get into tubed equipment but was shooting more towards the preamp than the amp, with thoughts that SS amp did better in handling the bass than tube. I'd love to borrow a good tube amp to try but unfortunately I live in flyover country and do not have any audiophile friends nearby. I would also note that my speakers are rated at 91.5 db, which, IMO is borderline capable of low power SET. And given my room size, I've been somewhat skeptical of going in that direction. I did consider it before I bought the CJ 2500A,
Again, I'd like to thank you all for giving me much info to consider. I will be gone for the next several days due to a death in the family. And when I get back I will address the problem and keep you posted as to the results
Hug a loved one today. We are not promised a tomorrow

Loading via the Y connector "works" fine, but as you suggest it is not optimal because of the excessive lengths of wire involved. It is even remotely possible that you are picking up RF on your phono stage as a result. That could certainly cause a sensation of brightness. Also, 42 ohms seems a rather low-ish load resistance for your cartridge, but that would not seem to be a culprit in causing brightness. Does the Wright phono preamp use a built-in SUT for LOMCs?

IF your speaker is truly as sensitive as others say (except for Maril), then when you couple it with a powerful SS amp, you are hearing only the first few Watts that such an amp produces. Many such amps don't sound very good in that area of their power curve; they tend to have rising distortion at low power outputs. From what I read above, this is a possible source of your problem, but it seems controversial whether your spkrs are truly as efficient as some say. Anyway, you had the same amp/speaker combo with the previous rig, so I would tend to think the issues are at the phono preamp level or before that in the chain. But before you spend big bucks on an entirely new preamp, you might consider cheap stuff, like soldering that load resistor closer to the signal input and things of that sort that have been brought up by others. Tube swapping might even ameliorate the problem. Replacing coupling caps also might help, if you are handy with a soldering iron.
