The stud cleared all but one ram to a high of $3400, up $600 on last year.
The average price rose $150 to make $1288 on 52 rams sold, an extra five than last year.
The top ram was bought by long-term client Nick Maddern, Cummins, following strong interest in the ram at the EP Merino Expo at Wudinna in July.
The sire weighed 110.5 kilograms and carried a 21-micron fleece with a comfort factor of 99 per cent, co-efficient of variation of 13.9pc, and standard deviation of 2.9.
Mr Maddern hopes the infusion of the sire's genetics will help plain up his flock as well as boost size and wool production.
Volume buyer was again A&T Robins & Son, Yeelanna, who bought 16 to $800.
Sonja Robins said as well as the quality sheep which have brought much improvement to their commercial flock, she keeps coming back to the stud for the "extra mile" Brimanna's Jayden and John Harris go to in helping clients.
"They are very client-focused and we appreciate their positive input to our commercial operation," she said.
Other buyers included new client GW&PJ Hodge, Lock, with four to $2800; MB&KP Proctor, Yeelanna, four to $2400; RK&DA Campbell, Mount Isabella, Karkoo, three to $2600; and GR&M McLachlan, Yeelanna, three to $1000.
Brimanna classer Paul Cousins, Cousins Merino Services, Burra, said it was the most even line-up he had seen by the stud in the seven years he had been classing the Brimanna sheep.
"The rams are bigger and brighter-woolled sheep with good definition," he said.
"All are true to type which gives commercial buyers confidence in what they are going to breed."
Studmaster Jayden Harris was very pleased with the auction, which delivered their best result, and thanked the support of both new and return clients.
Landmark stud stock's Gordon Wood said although the highest average price was reached by the stud, there were rams available for clients at all budgets and many were secured between $800-$1000.
For most of the top-selling ram's life, he had been called 'Gordon', a namesake of stud stock auctioneer Mr Wood.
However, the ram's luck seems set to change with a new lease on life because just after the Maddern family paid top dollar for the ram, Mrs Maddern promptly renamed him 'Jaffa' after Brimanna's John Harris.
