Rowland Model 10 - Break in Help

I am currently trying on dealer loan a Rowland Model 10 that's replacing a BAT VK500. Th Model 10 was new and now has 125 hours on it. The amp is set in high gain mode for ineffecient 83db speakers. While it shows the possibility of being the great amp I heard at CES in three different systems and improves every day. I am fustrated at this long breakin time leads to two questions for all of you.

How long does it take for the upper midrange hardness to go away?

How long does it take to be broken in so I decide to whether to buy it?

Thanks in advance for any insight you can share.

the anomalies you attribute to the amp may never go away with the associated ic's and frontend with which it's matched, even if your scheduled burn-in period is the same as the half-life of plutonium. please understand that i'm not casting aspersions on your gear but "these things go together." yin without yang is the sound of one hand clapping. -cfb

Kelly,

Thanks for the prompt feedback. You may be right my associated equipment may not be up to the task (see below) but when my current BAT Vk500 is in the system it does not have the upper midrange glare the Rowland Model 10 currently has.

Are you fimilar with the breakin curve of the Model 10 Amp?

The rest of the system is
Sota turntable Circa 1990
SME V/Benz Ruby
Madrigal Transport, CD player and Digital cable
Rowland Coherence I (original model)
Amps as discussed
Mirage M-1's circa 1990
Transprarent Ultra or XL interconnect CD to PreAmp, Preamp to Amp
Transparent Ultra XL speaker cables
Dedicated lines with FIM Outlets
Tice Power Block and Capacitor Unit

Al

P.S. In my system, the Bat took between 200-300 hrs to breakin

P.P.S. I wouldn't be making these amp changes if my Rowland Model 5 hadn't died three times 2 years ago.

Hi Dral, I have the Model 10 and I never experienced upper mid range hardness. What is the rest of you system? Also the high gain has to be set internal.It increaces the gain from 26db to 32db but this does not give the amp any additional power.How are you running the amp balanced, or single ended, and do you have the switches in the right position.Does you dealer know that your speakers are 83db because this amp is only 150 watts at 8 ohms.If you have any other questions you can e-mail me
