Very interesting. It seems that this preamp can be associated to a wide range of Amp… Good to know. :cool:
This is a new generation of Bryston. It gets enough power and fine sounding.
The main question of passive pre amp is most likely from the gain output of the source. Once the output gain fits the need of the pre amp (the modern dac indeed helps a lot), the strengths of passive pre amp are easily shown up. :):)

This special version of Bespoke silver TVC has arrived at the hk dealer last week.
My friend Paul has not picked it up yet so I went for a brief audition yesterday.
Although not burned-in it gave a huge soundstage, much bigger than the demo Bespoke copper version at the dealer showroom.
Great potential!
I guess this may be due to the bigger TVC copper enclosure/cowl of this special version.

Had an audition of this grand and beautiful passive pre amplifier last night. The soundstage is amazingly wide and deep.

My Bespoke Silver preamp is on the road again!

20200208_065330~2.jpg

It's because I am sending it back to Harry & Lucy for upgrading to the spec of Ultimate Silver version, similar to the one owned by Matej Isak of monoandstereo.com
This is the photo of such version :

The main difference is the cowls (outermost enclosures of the transformer).

For the usual Besopke models, the transformers are put inside mu metal shields first and then into aluminium alloy outer enclosures.
This is the internal photo of my Bespoke Silver :

On the contrary, the cowls of Ultimate version are made with brass and are of bigger size :

They are also beautifully plated with true gold :

Due to the diff materials and sizes of the Cowls, the Ultimate version gives a significantly more effortless sound and a much bigger 3-dimensional soundstage.

Initially I was uncertain whether the upgrade was feasible or not, but Ben Lau, the HK dealer asked Harry & Lucy at the Munich Show last year and the answer was affirmative.

Therefore I laision and group together several Bespoke owners in HK and send our Bespoke, some copper some silver models to UK for the upgrade.

Will update you on the progress.

Hi @CKKeung , so if I understand it, the change from mu metal transformer enclosures to bigger gold plated brass enclosures is supposed to make a significant difference in the sound? One has to wonder if it's not the case that the mu metal enclosures are somehow deficient in the first place. When do you expect it back?

The size of the transformers and the mu metal shields of the usual models and Ultimate version are the same.

The only diff is the larger gold-plated brass cowl. There is more filling beewax inside them too.

The mu metal enclosures are still in place but not visible. The stock visible enclosures housing the mu metal encased transformers are made out of aluminium. These outter aluminium enclosures are the ones being replaced with larger brass enclosures (and more beeswax damping).

I wish they included a bigger cabinet with the upgrade. The cowls sticking out of cutouts on the top plate look out of place.....

I personally like the look of the Ultimate Silver version very much, even though the original top-plate of my Bespoke Silver is gorgeous!

I didn't sent it back with the preamp.
Will keep it as a souvenir.
