Plus one of the major advantages we will have is we will be able to offer cartridges and phono stages which will match identically (impedance, loading, capacitance, gain requirements etc.) to provide our customers with predictable performance.

Very cool!!!!!   :thumb:

Nice looking turntable!
Do I upgrade my 7BSST/2 to the cube or buy the turntable?

Hi James,

Just an idea of course for you to consider for an alternative finish.   I would say though that the leather finish looks very nice.  I also have a clear perspex finish on my other turntable quite nice as well.

I think you will be happy with Bluenote if you decide to go ahead as I've been happy with their after sales service.

Good luck

Rod

Hi,


For this years Recordstore day, What Hifi's record special edition: http://links.em.whathifi.com/servlet/MailView?ms=MTQyNDExODgS1&r=MjI0MTUxNTU5NQS2&j=NzYxMTE2MDY2S0&mt=1&rt=0


Of special interest of course since Bryston's announcement : How a (Rega) turntable is made: https://youtu.be/IxdGdyVD6cw


have a great RSDay!


 


Cheers,
Marius

My bias: Go for the amp upgrade!  Bigger system-wide impact.   :thumb:

Can't wait to see a pic of an all Bryston TT only system. :thumb:

Heres mine waiting for the new Bryston TF2-20 Step up Transformer:

As I can see I'm a little late to this discussion, did you look at any direct drive tables or manufacture of parts and build your own plinth. http://www.langer-audio.de/Page8.html. I still have and enjoy an old Technics SL-7 linear tracking table, the only problem with it is the cartridges are a P mount and very limited in what you can buy for it. Also on a separate note, is the MC/MM in my BP-26 up grade able .

HI

Yes I was looking at working with Stanton but decided on belt drive. 

When you say upgradable do you mean if you change your MC cartridge we could change the loading characteristics of the step-up transformers.  We could replace them when a diffeernt version but they come in 2 version currently 20 dB and 30dB of gain.

So it would only change the gain in the pre-amp not necessarily the sound? Or would the sound change also? Is there any other changes in your newer updated tranformers?

Hi

To match the cartridge you have to look at the output impedance of the cartridge and the gain because you do not want to overload the MM phono stage.

For example I have a Benz MC on my prototype table. It has .8mv of output and wants to see more than 200ohms  as a load and 56 DB of total gain through the total system. So I have setup our new TF2 MC transformer to reflect that requirement.

Hi Folks,

The new 1/3rd size phono stage is based on the BP 1.5 - a review below.

MEMO: To All Bryston Customers
SUBJECT: Bryston TF-2 Moving-Coil Step-Up Transformer


December 2015

Most Moving-Magnet phono stages expect to receive a signal between 3-6 mV at their input from the cartridge.



A step-up Moving-Coil transformer is designed to accept the lower voltage output from the MC cartridge and increase the voltage to a point which is acceptable to the input stage of the standard MM phono section.

The Bryston TF-2 Moving-Coil step-up transformer is available in two versions...with a 20dB or a 30dB gain option.

Your choice on which unit is most appropriate will be determined by the voltage output of your chosen cartridge.

• From .1 to .2 mV we would recommend the 30dB version

• At .3 mV we would say either version would work fine

• From .4 to .5 mV or more we would recommend the 20dB version

An important point to consider when choosing which Step-up to use is you do not want to over-power or under-power the MM phono stage. 

Under-powering results in not having enough GAIN in the system and over-powering can result in voltage overload and the resultant distortion.

Hi James

I've only heard a phono stage with an active headamp.

 In your experience what are the sound qualities that a passive step up transformer brings to a phono stage?

thanks

Hi

A Moving coil cartridge has a very small 'Voltage' output but a very large 'Current' output. So in my opinion what you want to do is work with the large current output rather than the very low voltage output of the MC to optimize the noise floor of your phono system.

So the passive step-up transformer "transforms" the high current output from the cartridge to high voltage which is required by your MM Phono stage. The quality of the transformer is critical of course and the cost is generally much higher than an active headamp but in my opinion it offers the best performance. 

If you look at high performance MC cartridge manufactures they generally offer step-up transformers as I believe they are cognizant of the advantages as well.

Hi James,


looks very promising and congrats  to Bryston for extending your product line. :thumb:

will  there be  a wood  finish option (burl or cherry etc...)  in the future plans  of the TT?

 
any tube gear plans with Bryston  in the future?       (phono or  preamp)


i admire companies  like Bryston. who  continue  to bring great technology to the audio community  and their customers


Cheers

HI

For the time being we will just be sticking with Black and Silver as we have to buy a lot of tables to qualify for proprietary manufacturing and adding different finishes would be very costly.

No chance of any tube products from Bryston.

Its easy to see why you've picked Bluenote to manufacture your new Turntable as they have always had great quality and engineering in their products.
And then adding your own expertise for a power supply design. :thumb:
