SET amplifier (for AvantGarde Duo's-original) recommendations


Hello all,
I inherited the above speaker and I have been really enjoying them.  I also have a pair of Thiel 3.7s- paired with pass labs xa60.5's (and it works!) which I also love albeit they are very different animals from the DUO's as you can imagine.

Right now I am focusing on the Duo's and have used them both with Pass Labs and a Mastersound Compact 845- both are great but there is something about the DUO's driven by this 845 SET that is magical.   The problem is that the 845 was dropped and developed a hum.  A technician went through it and managed to reduce the hum but it is still there and it bugs me- I am not sure if one of the transformers itself may have been damaged and that isn't really repairable at reasonable cost, though I will speak to Mastersound to hear their thoughts. I should add that the amp used to be dead quiet and generally Masetrsound makes superb amps- and are renown for their transformers.

So I am now starting to think about alternatives solutions- I would like to either stick to a SET of comparable quality (that is known to be relatively quiet with efficient speakers)- maybe a 300b type just for a change, or even an OTL.

There's a lot of stuff out there at the moment, take the Line Magnetics that are floating around (but would they compare to Mastersound in terms of build quality etc?) and I was hoping to get some insights on what you think would work well.  I have read a lot of reviews and while helpful at times I feel they are almost always positive and a little too generic  when comparing similar products.  I'd like to stick to a $5k or so budget (therefore I would look for something used).

I can suggest the Erhard Ray. Listening to it right now. Will come in under way under budget. Dead quiet. Premium transformers. Suggest you wear Depends as you may lose control of bodily functions.

What a cool set of speakers. at 110dB, you need one watt or less in most listening situations.

I have a Tektron (italian maker) Amp that uses 45, 2A3, or 300b and the 45’s are less than 2 watts and more than enough with my 96dB speakers. The 845s are actully way more than you need. Mastersound makes great amps. Sorry this one isn’t doing well.

Decware makes a magical 2 watt amp, the SE84UFO2. You’ll have to find one on the used market since there is a 2 yr wait. If you go on the Decware forum and post that you have an utracool set of speakers that you’d like to listen to with a decware amp, a local owner will likely bring his amp over for a listen. I would.

The new Aric audio 2A3 looks interesting but I haven’t heard it.

Or have an amp custom built. that would be the way to go.

SET is the way, in general, but they are made for your speakers. A 2a3 would be a very good combination. I own a company called Apollo Audio Systems that focuses on this topology at the highest standard. Proprietary/domestic/hand wound iron, the finest audio path components in the world, lifetime limited warranty, personal support, ease and low cost of ownership and full customization options to match your other gear, the color of the horns, etc. The list goes on but I will put my gear up against any of the big boys. I have yet to find anything on the planet that will outperform Apollo gear at any discernible level or cost. I'll send you some pics if you're interested. End game gear is what I do and those speakers def deserve more than Line Magnetic or Willsenton. 

 

With the Avantgarde soeakers what really matters is speed. I suggest you llokmat Atmasphere or Wavac. alternatively Ken Shindo’s higher end offering might get you there. No need to bother with Audionote or Kendo
