robmid Posted April 11, 2017 Share Posted April 11, 2017 (edited) 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. Edited April 11, 2017 by robmid 2 Link to comment Share on other sites More sharing options...
greigw Posted April 11, 2017 Share Posted April 11, 2017 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. 1 Link to comment Share on other sites More sharing options...

Guest Posted April 11, 2017 Share Posted April 11, 2017 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 Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...

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 1 Link to comment Share on other sites More sharing options...

Luc Posted April 11, 2017 Share Posted April 11, 2017 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 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?

rantan Posted April 11, 2017 Share Posted April 11, 2017 @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 1 Link to comment Share on other sites More sharing options...
Aussieamps Posted April 11, 2017 Author Share Posted April 11, 2017 Hi Rantan The 050 amp can be configured for balanced and RCA inputs so it would match nicely with your existing Preamp outputs. Link to comment Share on other sites More sharing options...

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.

Aussieamps Posted April 11, 2017 Author Share Posted April 11, 2017 It a fairly straightforward up grade requires a larger power transformer and higher supply rails. the higher power version is additional $300.00 1 Link to comment Share on other sites More sharing options...
