Power Amp.

Hi!

I am thinking of upgrading my system and give some more juice to my speakers…
Currently I am running my B&W 803D2 with Primaluna Dialogue Premium HP int. with KT150.
I have found this combo very engaging and really have no complaints except I cannot reach the high level to enjoy orchestras play.

As always there is the budget factor that destroys ones dreams however, this time I have decided to opt for a good (possibly 1 time buy) power amp and a decent low budget pre till some $$ can be saved.

The pre will be the PRO-JECT PRE BOX DS2 ANALOGUE so, good or not it is a choice for not getting an integrated again.

Main question is for the power amps.
At the price point I can extent, following are considered:
- Bryston 4B3 cubed series
- Rotel Michi S5
- Gato PWR-222 High End Mono Power Amplifier (x2)
- McIntosh MC462

At the end step (after changing the pre), I do not want to lose the warmth, clarity, and stage I get with my current setup. Also, the full bodied music I can hear at ridiculously low levels.

At best I will be able to hear the Bryston and the Gato. The other are only available on order.
Personally I am a bit in favor for the Bryston. It is not the most powerful in the group but, not sure if I will miss the 2 dB I.e. compared to Rotel if it’s sound comes closer to the tubes one. I should be able to audition next month…

Any ideas / comments?

Cheers

Bryston 4B3 is an amazing

Bryston 4B3 is an amazing machine, real dual-mono, separate power and transformers. And (important to me!)- made in Canada. This is the only amplifier from your list that I actually heard.

Another amplifier you can look at is Accuphase M6200. It has a similar designto 4B3, with arrangement of two completely identical amplification circuits. It also has very low impedance (1200W into 1ohm. A close friend of mine has this god-like machine and its ownership remains my personal goal. If you get a chance to check it out, don't let it pass by.

Good luck!

Just a thought

For the kind of dough you are planning to spend and the aim(s) you intend to achieve, why not plan a or a few weekend trips to audition the other two amps that you don't have easy access to? Of course, as I assume you already know, in order to achieve fair assessment(s) of the equipment involved in these trips or auditions, the trips should obviously be scheduled and carefully orchestrated so as to replicate, as much as possible, your home sound room acoustics & equipment. I haven't heard the specific amplifiers you mentioned but have done serious seat-time with Rotel and McIntosh amplifiers, over the years. For that kind of moolah, I would encourage you to have a serious listen to the big MAC on your list. There's a review of it here in Stereophile. Good luck with the heavy lifting!

Many thanks for your input

Many thanks for your input, it is highly appreciated.

During past time I have been visiting dealers to demo power amps.
I managed to listen all above except from the MC462 however, I did listen the MA9500 though, it is not the same…

For my personal taste, I struggled to decide between the Macintosh and the Gatos while the Michi was the first to rule out and the Bryston the second.
Nothing wrong with any of the equipment, just what feels right in my ears.

Final decision was to buy the Gato Pre-1 and two monos PWR-222 on a very good deal made.
Can’t describe how happy I am to finally get a complete pre and amp setup

Cheers
