Are you aware that many Troughlines have incorrect de-emphasis capacitors, so they introduce a treble shelf? This will make it sound 'warm', so other (correct) sources will sound a bit thin by comparison. Yes, the Troughline sound which everyone likes is caused by a design error!

I will when I am able. However it's a 12ax7 preamp. It's built with the tetra board. I have checked and its RIAA accurate. Short leads from TT and amp. I also have a SS battery powered per amp. No real difference. Got to be something else. Maybe the arm, the plinth? The cart gets good reviews

Try increasing the load capacitance if you can. I've heard Ort. OM30's sound really "bright" into some RIAA's. Maybe the 2M's are similar for loading?

What is the output stage (impedance) of the phono pre-amp?

I am glad with the subjective comments of the thread starter. I'v had this same experience during a number of phases in my audio-history and never understood them well. In the seventies I had several tuners with which I have heard live broadcasts that were unbelievable good. I had Stanton 681EEE element in my turntable and when listening to a decent station on FM I very often could not help thinking that this was way better than the phono. I even went so far as to write to the station to ask which cartridge they used in the studio (Shure M75 and dozens of filters en limiters!).

And strange enough this effect seems to repeat itself in internet streaming radio. I listen to mp3-streams that can not be better than my own cd's, but nevertheless I enjoy them more.

I know of some amplifiers that deliberately use some treble-tailoring to sound more easy on the ears. Maybe it's an illusion to think that the most 'straight' amp or source is the most pleasing to the ears. But this is the end of high-end?

Hi-fi is about the closest approach to the original sound.

High-end can be about taking money off the gullible, who then actually brag to their friends about how easy it is to take money off them! People sometimes assume that high-end is the excellent end of hi-fi; it is often just the expensive end of audio.

The "mid-end" is where all the excellence is.

The system needs to be heard to come to any meaningful conclusion as to what may be astray.The Troughline tuner like all r.f. equipment of that era could be out of alignment and the de-emphasis cct could be wrong as has already been suggested.Perhaps other front end components could be substituted; certainly another pre-amp for a start and for interest,how do C.D's perform in comparision?
