Best value Set amp for under $1500 used is ok.

Looking to power some large horn speakers and replace my SS Audio Research upgraded LS10 power amp because it needs service and I am not ready to service this unit for a variety of reasons not worth discussing here.

Specs for the Viking Acoustics L’Instrument speakers

 

are:

Sensitivity: 98 db

Time Alignment: Drivers time-aligned mechanically and electrically.

Bandwidth: 18Hz - 19,000 (18Hz - 50kHz with optional super tweeter)

I have tried 845/805/KT88/120 in non set builds. I’d like to try a 300B or similar set  design for these without burning the budget. I’m based in Australia and prefer to use 240V capable amps.

Here's something else to look at.

It's a 1 watt preamp/headphone amp/speaker amp that could also be used as a preamp with your ARC.

International voltage with the stock power supply and within budget

I've read about it (online reviews) being used with higher efficiency speakers, but I don't know how they would compare to yours.

This said, I owned an Audion Silver Night DH/SET 300B amp years ago and it was perhaps the most fun I've had in this hobby.

I now use inexpensive (kit) DH/SET 2A3 mono blocks to power vintage wide band single drivers.

@johnread57 Well, congratulations on acquiring this amplifier. I’ll admit that I’m unfamiliar with this brand. It’s certainly affordable and that is nice. I hope that at its price point it utilizes decent/reasonable quality transformers (Particularly output) and power supply. Two important factors for amplifiers and especially SET amps.

I am very interested in your listening impressions and how well it pairs with your speakers (Which on paper is a very good one). This should be an exciting and informative endeavor for you.

Indeed @charles1dad  the price was the key feature along with many reviews. I have a Krell DUO XD300 in the process of sale that will fund this purchase. Then I may also fund the repair to another D240 MK II that was destroyed by FedEx who would not accept a claim against them. 
Hopefully this small purchase results in acceptance by my wife as we were listening to Stockfisch SACD simply on YouTube last night and marveling at the sound just through our cheap Marantz 1509 AVR. Super surprising. Demonstrating what great speakers bring to a Hi-Fi system. Appreciate your interest here too.
