I am enjoying my analog system, but what can I do to improve?

@rauliruegas, that poster obviously has not heard them with the right amplifier.

@chungjh , I think your ears then are not used to higher volumes. Start at lower volumes and slowly add 5 dB every few minutes and you will get used to the volume. Sound Labs will make great bas down to 30 Hz or so before cancelation wipes the out. Your not adding subs for bass (unless you really want everything below 30 Hz). You are adding then to relieve the Sound Labs from having to make bass. The result is much less distortion. 

@mijostyn , talking to Roger West, the owner of Sound Labs, having subwoofer introduces discontinuity and also loss of clarity in bass.

You probably did not talk to Dr. West, as he is very hard of hearing if not actually deaf, and he does not talk on the phone to anyone. You may have exchanged emails with him. I have done so myself, and he is a very nice man and very tolerant of his crazy customers’ questions. As to your description of your issue, I don’t know what to tell you except that all of this stems from the small listening space. Also, I have found that the dynamic contrasts on an LP vary from one record to another. Some are much more dynamic than others. For example Reference recordings are always so dynamic that even in a large room I too have trouble settling on a position of the attenuator that gives me tolerable crescendos and audible diminuendos. It’s just something that comes with the territory of being an audiophile . Are you saying that this issue of dynamics occurs with every LP you play? If so, I would be surprised. I don’t think this is because you have too much amplifier power or that your speakers are too good. The speakers are just responding to the signal that is put into them. They don’t care how big or small the amplifier is. As to using a single ended tube amplifier with the speakers, that is very much not a good idea at all. I know of no such amplifier that can drive the sound labs satisfactorily , for one reason because they have a dip in impedance at mid frequencies which no SET amplifier could deal with very well. As I think you know, I have measured impedance versus frequency curves for my own 845 PX speakers, which supports what I am claiming. Your 545s will have an updated crossover and treble transformer compared to mine which partially ameliorates the problem (for any tube amp) but probably not completely. Not a problem for a Pass amplifier.

Lew, I find the dynamic range too high only on certain recordings. May be that is the way it should be for those recordings. BTW, I moved my seat as far as I can and it sounds much better. Much more natural and less “in your face.”

Dear @chungjh  : I already talked about why we need to listen our room/system seated at near field position. Please re-read my post.

In any room/system the seat position of the owner is critical for several reasons that includes each one of us hearing lossed, SPLs each one of us prefers and so on.

Good that you improve changing your seat position and then you need to follow about from where you are testings with small/tiny seat position changes looking to find out the " rigt " one position and remember that behind that seat position should be romm/treatment too.

In the other side, try that your audio retailer browse to you at your place a Pass preamp or something similar to the Pass one.

No, it's a very bad move to change the 545 speakers for other speakers when the trouble is not there but is up to you.

Btw, o you already tested 3-4 different hedashells with your cartridge and tested with different headshell wires than the stock one?. This was my advise to you in your tread in 2021. Again, is up to you because I really don't care if you did it or not because at the end is you who must live with that audio system.
