Bose 4401 + 1801

[mm54]

hello to all members,
i am from France
I am new on this forum and I read with great interest the various topics .. we might lose!
For a long time I wanted to realize a childhood dream:
have a hifi system 70's old with JBL speakers, I like these speakers, I had long ago 4311B of which was beautiful but unfortunately I could not keep them ..

My first purchase was a Studer A810 that I got in Germany, a beautiful tape

Second , i acquired a few days ago a couple BOSE 4401 + 1801 that I should receive within 1 week.
I do not know if it's a good set but the blow of heart for me !
pictures in a few days
I want to have your opinion about the best JBL speakers that I can set this amp + pre amp?
I have also the possibility to use 901 but i dont now this speakers
If anyone has information on patterns, materials, connections, manuals on this BOSE couple....

then he should choose a CD player, a turntable, a tuner, all of which should be 70/80 years

Thank you
michel

I want to have your opinion about the best JBL speakers that I can set this amp + pre amp
I would like the JBL L300 SUMMIT , there are very beautiful on ebay U.S.($3650) but the transport price is too high for France(about $2500)

Halo Michel,

I have a BOSE pre amp and power amp, the same as you bought.
I have had allways a pair of BOSE spaekers. But they are gone.
I am looking to buy my old JBL 4343B speakers back. I sold them years ago to a small studio. But the owner is now selling his stuff.
The BOSE is good material and the JBL's will sound great on the Bose 1801.
I also have a turntable Technics 1201, Nakamichi cassette deck,
Revox B77 recorder.

Send me some pictures,

Hi Ronnie Dagevos thank 's for reply,
i have received my BOSE1801+4401 and the cosmetic condition is mint !
actualy i cant test it because i have no speakers no CD and no tunrtable.
In few days i must go to pickup my L300 SUMMIT...

I must be patient to buy a very good CD ,i thought of STUDER D730 and turntable EMT948 but I will wait ... if you have a Id for other products 70/80 years

i have received my JBL L300 SUMMIT 1976 and tested with my BOSE1801+4401,
when I connect my turntable Luxman PD277 (coil MC) on the preamp BOSE4401 on IN switch to 1 or 2 for hight or low position
there is a steady background noise every second
if I connect to my Accuphase amp on MC phono1 it works properly
I think there is a problem on the preamp BOSE4401?

is it possible he does not accept MC entry ?
it seems yes on the manual but it is a copy and I can not properly read
the part that corresponds to the connection of a phono1 or 2

if impossible can i use outside adaptator...
since MC to IN adaptator and OUT adaptator to IN PREAMP PHONO1

Hofmannhp say the output of a Mooving Coil phono cartridge doesn't fir to the 4401.
therefore you need a Preamp with an MC input.
I suppose it is Preamp Phono like Clearaudio

the user manual says that the 4401 is compatible with the magnet coils MM
I would rather a problem with the phono stage of the 4401 which is more serious, I is not a means of control should be another person who uses the 4401 and which has a turntable with an MC cell if that work ??

[mm54]

i think Hofmannhp have the good answer,
the 4401 phono sensitivity is 2mV (for MM cell) in phono1 and 2
and my cartridge is :
CELL MOBILE REEL (MC) - DENON DL 103 PRO Voltage Output (1kHz, 50 mm / sec): 0.35 mV (1KHz 50mm/sec) Frequency response in Hertz: 20 - 75 000 Impedance Output (20Hz-20kHz) in Ohms: 38 Channel separation: More than 26 dB difference in sensitivity of channels: <1 dB Pointe reading: Elliptical diamond Flexibility dynamic (100 Hz): 6 x 10-6 cm / dyne Force Support: 2 g + / - 0.2 g Weight: 8.5 g

my question :
if I shall make a phono preamp type Clearaudio which has come between the phono and entry platinum phono 1 or 2 does it work or do I use the auxiliary input of the preamp in this case I'm bothering because I use the auxiliary input for my CD?

what kind of cartrige does i use to have better sound ?

Have a search for a MC step up transformer. Denon AU 320 is ideal but there are others available.

You have two problems with the input to the Bose pre , the voltage does not match and therefore the bose must create extra gain to compensate. Because of this the background noise and hum increases also.
You may also have a ground loop problem related to the turntable.

The Denon carts are not noisy.
