Beautiful craftsmanship and a bargain! I have a larger Holton kit built amp that cost about the same and absolutely love it.

 

This amp would be a match made in heaven driving KEF LS50's in a normal sized listening room.

I heard this last week sounding great. It's so quiet it give me a fright when the music started. The finish is very high quality. It's a bargain at this price. Apparently it paired very well with my wyred 4 sound stp se preamp that was in Anthony's workshop for a checkup.

I've heard the prototype of this mate. It would be a nice match for the sexy little KEFs.

Looks great. Do you do a pre and/or an integrated also?

This is highly evolved advanced power amplifier cutting edge stuff, with more than 25 years of power amplifier design put in by a pro amp builder that is normally involved in building mega monster amps for the Audiophiles of Europe. I personally wouldn't underestimate the hifi character of such a beautiful well presented piece from the Holton Foundry where this was struck

 

The amp is built of milled aluminium plate the thinnest is 3 mm for top and bottom covers, billet mass loaded feet

The center mezzanine the 7mm front and 5mm back acts like a mass damping heat sinking structure to eliminate physical noise from the transformer and keep operating temperature low

It has on board speaker protection and soft start that is processor controlled with solid state relays at the speaker outputs to protect those very expensive drivers and dividing networks

It has 80 000 uf of capacitors on board which is normally reserved for amps 3 times it's size

Australian Made Harbuch 225va Transformer which is engineered to run at 100% of its nominal rating  100% surge ability

It does run a pair of Martin Logan CLS's in an addictive way meaning if dinner is on the table and you want to finish the track, you will leave the dinner a min to finish the track, inviting and transfixing detail, soundstage and 3D image.

It sounds warm and timbred on the ML's like a very good 300B tube amp.

The circuit board quality is normally reserved for only the World's best, 2 ounce copper through plated with gold and has SMD and through hole components of exceptionally high grade and accuracy, the best one can get actually

 

It's designed for a lifetime of enjoyment and ultimate reliability on any speaker system, for me personally a keeper as I have built 2 and have 2 more to do, which will replace some monster amps on a highly efficient PSE144, 4 way stereo rig that has been under development for a year or so. The thing is, they are just, better, quieter on 107dB horns and desirable after a taste

 

The amp has the most minimal noise floor, no physical transformer hum and has been well vetted by it's maker and myself as a quality piece of loved hifi kit in a 300 x 200 x 100mm package.

 

THere is plenty more I can say about this Holton 050 Rev 1.5, 50w x 2, as in it can be upgraded easily to 100w x 2 and already has an add on update for the driver stage  the Maker has been playing about with

 

BARGAIN, cost me more to actually have the parts made/purchase, even the transformer is small batch custom and not available off the shelf

 

GLWS Anthony

Just to help out, there is almost literally no more room in the amp for "integration stage" or quality pre amplifier to suit the myriad of cartridge loadings,

 

its a power amp and the final stage from your other quality seperate compontery

Fair enough. I do get it that space maybe at a premium, but finding a synergy with a pre amp is time consuming and not always successful

Indeed. The thing is, I have zero interest in trying to borrow and audition a dozen suitable pre amps that may work well with it:)

Lovely looking bit of kit.

I had a yarn and a quiet beer last year with Anthony in the lounge/bar at Marc's show and he had his big amps on display and didn't want to take them back to Tassie and offered them at a  really keen price. And yes he was tired and worn out at the time. If I could of knocked a 0 off them I'd of grabbed them:love

But alas still way out of my league but I think Marc has them now in his system so perhaps they never went back over Bass Strait.

 

@Aussieamps  Anthony, what are it's dimensions and weight?

@Aussieamps

 

I have a spare integrated that I want to use as a pre amp. It has pre out facility so with your Zero Five Zero , would this be a straightforward input to your power amp?

 

This could make for a nice combination if so:)

Hi Rantan

 

The 050 amp can be configured for balanced and RCA inputs so it would match nicely with your existing Preamp outputs.:)

Cheers for that.

 

A couple of other things if I may. What is involved in the upgrade to the higher performance amp and what would be the approximate cost?

 

Thanks.

It a fairly straightforward up grade requires a larger power transformer and higher supply rails.

the higher power version is additional $300.00

      Price: $4000
      Item Condition: Very Good
      Reason for selling: Upgraded
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info: This is a legendary stereo power amplifier with quad matched Sovtek 6550 output valves which still have an estimated ~1000 hours life on them. These valves turn this already great sounding amplifier into an amazingly lifelike musical presentation. This amp's 60W rating belies just how capable this amp is at driving complex loads with ease. It still rivals most amplifiers available today. Despite being a valve amp, like all ARC power amps it is actually a hybrid amp with a solid state input stage and valve output stage. There is a minor warp on the tube cage and a cracked plastic capacitor cover (no effect on functionality). It is an original 240V one for the Australian market. This amp has been lovingly taken care of since it was purchased and I still have the original packaging and manual.
