Thanks for the advice, I'll see how that goes I usually listen through my headphones because my system is almost all the furniture in a quite spacious room (it's that and my couch ), so the sound through the speakers sounds very echoey.

Yes makes sense...big room, hardwood floors, not much furniture..sound can be like you said since there is nothing to absorb.
Again, if you can, a rug or something like that will make the sound a bit warmer, not echoey as you describe.
Or headphones work!! Do you still use the cassette deck?

Yes, the SD3030 is quadraphonic, so you can record on all 4 tracks independently and simultaneously, but I have never used it in that way.
And your TEAC is an object of great envy and desire :)

And here be, dear friends, a money-is-no-object audiophile system for men of means and fine taste from the faraway 1960. The sad thing about this $54K (in 2014 dollars) system is that there was no prog to listen to!

Nice article Argonaught.....Its cool to see what people back in the day used for gear.
Rek-o-Kut tables, HH Scott are still in use by some diehard vintage devotees.
Considering the $54K includes cabinet work, probably not a bad price for that gear.

is correct - they will sound less "chesty" if you raise them off the
floor and the stereo image improve if you move them further apart, also
tilting them back a little can sometimes make a big difference too.

Is there an easy and elegant way of raise them? I don't understand much about those kind of things

Or I could spend $54K on furniture I
only used the cassette deck once to record some vinyl singles to
cassette, but I only listened to that cassette once. I never liked that
format much, I guess I'm too young to understand it My mother uses it though; she has lots of cassettes

Thanks! By the way, you were right when you said that my headphones were great with solid state amps

The elegant way is to get some speaker stands.
The simple way of seeing if it makes a difference is to stand them on some books or a couple of house-bricks. The idea is to lessen the reflection off the floor and direct the sound more directly towards your ears, even with a rug or carpet the sound will be affected by such a close proximity of the speaker to any flat surface..

What?

Not humble at all, and very appropriate for listening to prog, because that's what your system would have looked like when prog was king, although I think your cassette deck is likely from the 1980s rather than 70s.

I never though about that, and it's cool now that I think about it You're
right, the cassette deck is from the 80s: my Pionner cassette deck from
the same set doesn't work, I'll see if I can figure out the problem one
of these days. I have a problem with my turntable though: it
makes some disturbing noises and I'm afraid that it might damage my
vinyls. I changed the cartridge two months ago and it still makes the
noises.

A common problem with cassette decks is the belt will need changing, it will gum up and stretch out too far to operate correctly, just open it up and look for it. That is a cheap easy fix to change the belt.
What noises are your table making? Is it motor noises or noises you hear coming thru the speakers?

It's sounds like a stone being dragged and it comes from the speakers.
EDIT: I solved the problem. I downloaded the service manual and noticed that the tonearm was lower than it should be: the distance between the stylus and the disc should be between 5 to 7 mm and mine was at 4 mm

Ok I was gonna say check out Vinyl Engine website, they have almost all manuals and great information on turntables.
Your tonearm should be parallel to the vinyl, this is your VTA (Vertical Tracking Angle). From there you can make adjustments based on your ears of either tail up or down slightly. Also to adjust for sibilance if that is an issue.....Sssss should sound as natural as possible. Of course a hot recording cannot be adjusted for
Glad you fixed it! Enjoy...

^ I got it on Vinyl Engine; I didn't find anywhere else. I'll check the VTA and I didn't know what sibilance was until now, but I don't think a have this problem. By the way, how do I know if a cartridge is compatible with my turntable? Is there a standard reference for the format?

Yes on VE there is a cartridge resonance evaluator under Tools. Input your tonearm effective mass in grams and it will give you a chart where you can find the RF (resonant frequency) your combination falls in.
You need to know the total weight of your cartridge and mounting screws and the dynamic compliance of your cart.
The top row is the total cartridge weight. The left side is the dynamic compliance of the cartridge, which you need to find out from the mfg website or in the VE database.
Cross reference the two and as long as you are in the green you should be good. Better if you are in the middle of the range, keep in mind this is an estimate, but should be close as long as your input data is good.
I have an excel sheet I use also if you tell me the following I can also check it for you.
Effective Arm Mass
Cartridge Mass with screws, washers, nuts
Dynamic Compliance of your cartridge
Or just tell me what make/model of TT and cartridge you have and I can find myself.

If you don't mind TT: Technics SL-BD20 Cartridge: Technics P24 (it's the original, I changed the needle not the cartridge) Thanks

What fixes the belt problem really well in cassette decks (and turntables) is DD.

So your SL-BD20 table according to VE has an effective arm mass of 13.5g including cartridge, since it is a P-mount system and also your VTF (tracking force) is fixed at 1.25g, you do not have a counter weight. Your overhang says 15mm but that should also be fixed again since this is a P-mount, but you can verify that. Overhang is the distance from the spindle to the stylus tip, if your arm will move that far.
Cartridge shows a dynamic compliance of 12x10*6 cm/dyne at 100Hz, since it is Japanese cart need to convert to 10Hz to get 21.6 dynamic, as that is what the VE calculator uses.
Those figures give you a 9.3112 resonance frequency, so your combo is good but not surprised since it is all Technics combo. You want to be in the 8Hz to 12Hz range, now this is just an estimate but usually pretty good. The best measurement is with a test record...I would only recommend one if you had a super high end TT/Cart/Arm combo and needed to match for different mfg.
You are in good shape!
Enjoy

Thanks for checking it I asked this to know what cartridge I should get if something appened to it or if I couldn't find other stylus to replace. In that case, if I understand correctly, I should get a light-weighted P-mount cartridge (since there's no counter weight), right? I listened to The Yes Album yesterday to test the changes I made and the sound was incredible compared to how it was: no crackles, no noises and it all sounded crystal clear. I still have a problem I don't know what it is: sometimes between two songs I can hear an echo of the first song and I don't know if it's a problem of the record or the turntable
