Valve amplifier choice



Hi Guys
I am considering making a switch from a Musical Fidelity Kw 500 to a lower powered all valve integrated or possibly a pre - power combination , i am due to move into a new house that has a smallish listening room 20ft x 12Ft , my speakers are Triangle Lyrr current model floor standing rated at 92db. Rega Dac as digital source , really fond of the smooth sound as in the past i have found cd sterile.
Although i enjoy the Kw 500 i was able to Listen to a Icon Audio integrated that really sounded nice , i also have had a crush on Macintosh amplifiers for some time now although not had a chance to audition due to living in Tasmania- Australia , there are very little in the way of local hifi outlets as it is a rural environment , i would like to get some suggestions for Icon Audio or macintosh valve integrated that would suit for a room of the above dimensions , I am a newbie valve amps with the Kw 500 being the closest i have come to with valves in the pre stage.

Thanks everyone.

I am not sure about what is available in Australia, that may be a big deciding factor. But maybe some of the tube gear from Japan or a reputable Chinese manufacturer? A lot of the Japanese gear that I am aware of seems to be fairly low powered, SET amps (Shindo & Yamamoto for example). For Chinese made gear, check out Line Magnetic (LM) and Primaluna.
Thanks Guys

It was not expensive , i think comeing in at around $2500
Australian which i thought was reasonable for a quality valve amp.
I kind of like Macintosh for you. Living in a rural Tasmania, I’m going to suggest that equipment maintenance and reliability with a company that has a solid track record should be a priority in your decision.

Hi Phaelon

Yes the Macintosh is very tempting as the backup seems second
to none and the reputation gives real confidence , at this stage i have a few pieces collected over the years in the hobby , at this time now i want just one nice system , i have moved on from experimenting and have found i have 3 of each component , The problem with living in Tasmania is that all the distributors are located in Melbourne or Sydney , any suggestions on Mac models up to say $7000 Australian. I also have a Wadia 302 cdp in storage but find the Rega Dac wonderful despite its budget price its "outstanding". I use Transparent Audio Reference speaker cable and Kimber Ks 1011 interconnect from dac to amp , i have come to realise a smoother sound i enjoy rather than high detail in your face which i find in most systems i have heard at retailers. I like Dire Straits , Neil Young , Gordon Lightfoot , Eric Clapton , not much into hard rock .
