  1. There are some interesting comparisons between two floor standers in the VA range, the Beethoven Baby Grand and the Beethoven Concert Grand in a post below: I have owned both of these floors standers for considerable periods of time, I upgraded the BBG to the BCG about 8 months ago and haven't looked back. I agree with your assessment, to me the mid range is nicer and the BCG also create a far larger sound stage. It was like going from being at the back of the auditorium to the front seats! Bass wise the BCG perform better, adding some noticeable improvement in the ability to reproduce lower bass with a bit more impact. This is by no means over the top and still in keeping with the overall neutrality of the speakers signature sound. I've found other brands 'sparkle' in the store next to VA speakers, however when it comes to actually living with them that sparkle actually becomes their downfall, with the VA's remaining beautifully accurate but no grating in the top end. In that same vane both VA's don't produce huge bass, but in my experience the BCG do a much better job of digging the sub bass out of electronic music with a subwoofer-esque like ability. Basically, where there is super low bass you get a much better 'kick' feel from the BCG's than the BBG's. I've ran both with Solid State and Valve gear (all McIntosh, MC275, MC302, MHA100, MA7000 & MA5200) and can say that they will punch lower with the solid state and create a bigger, but shallower sound stage. With valves you loose some of the super low end but the paring yields a beautifully rich, slightly narrower and incredibly deep soundstage which I found fantastically intimate with the BCG's if you want to listen at lower volumes. I've found the BCG's were pickier and prefer to be paired on a 4ohm tap over 8ohm, where as there was not so much difference (if any) for the BBG's. The BBC's were happy on either 8 or 4ohm. My old man has also just recently bought a pair of new vienna acoustics haydn grand which are also quite lovely. We compared them in store to B&W and Sonos Faber of similar and slightly higher prices and preferred the haydn. At the end of the day - choose with your ears! It really helps to go and have a listen.

Hope this helps and I'm happy to answer any specific q's you had.
  3. Sold - Thanks Guys.
  4. I wish i had a pair of MC302's, I just got the one sadly. I only had two MC275's as well
  5. Hahaha - no sorry - i'm on the hunt for an MCD500 or 550 myself
  6. Item: McIntosh MC275 valve power amp Location: Canberra ACT - original outer box and internal foam - happy to courier at your expense and risk. Price: prices are FIRM $3700 with brand new Gold Lion KT88, JAN NoS Phillips 12at7 & 5751, with a Russian Mullard in the v1. Item Condition: functions perfectly, cosmetically the unit has some light marks on the stainless steel and some lettering in some places is lightly worn. Please see photos. Pleas note the amp is also missing the Tube Cage. Reason for selling: this is the last of the pair i was running, I recently sold the first one on stereonet a month or so ago. I was offered a great price on a new MC302 and now I'm looking to move this on. Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: The MC275 is a hifi icon in my mind, beautiful design and sound. I've found 75watts more than ample power for my Vienna Acoustics Concert Grand speakers. Happy to demo if you are local or want to make the drive. All photos below are of the amplifier - just added this 'glamour' shot of it which was taken with a real camera and not and iPotato:

  10. If you are into audio engineering or want to read abou how the autoformers work: " Transistor power output circuits can match 8-ohm loads directly. This eliminates the need for the output transformer for most manufacturers. However, output stages that are designed to operate into an optimum load of 8 ohms can double or quadruple heat dissipation when operating into 4 or 2 ohm loads. At some frequencies, speakers rated at 8 ohms can dip as low as 4 ohms. Some 4-ohm systems can dip even lower. This mismatch can cause the amplifier to exceed its thermal dissipation limits. On the other hand, if an amplifier is designed for an optimum load of one or two ohms, a low impedance load would be no problem. However, less power would be available for a speaker having 4 or 8 ohms impedance. The unique McIntosh output autoformer was the answer. Since McIntosh output stages were connected in a single ended push-pull circuit, one side of the output was always connected to ground. They were typically designed to work into an optimum load of 2.1 ohms. The matching autoformer was connected directly to the output. In the MC2505 amplifier, the matching output was for 4, 8 and 16 ohms. Other impedances became available in later amplifiers. Full continuous amplifier power could be delivered to each of these loads. There qas no danger of exceeding safe limits or overheating. The autoformer also protected the speakers from damage in the event of amplifier failure. Should a direct current component appear at the amplifier output, it was shunted by the low DC resistance of the autoformer, instead of passing through the speaker voice coil, which could damage the speaker or even cause a fire. McIntosh autoformers continued to be used in the "top-of-the-line" amplifiers. They were all designed and manufactured by McIntosh. Although the autoformers added extra cost, weight and took up extra space, they assured a safe, optimum match to a variety of speakers and speaker hook-ups. They were constructed and performed in the McIntosh tradition of excellence." http://www.roger-russell.com/mcintosh1.htm
  11. Ahh yeah the Autoformers were designed by McIntosh to handle exactly those sorts of issues.
  12. There's no doubt double the power using two and the McIntosh autoformers easily deliver all of it at 2ohm in mono. With my speakers the 4ohm taps sounded best as a single amp as well as with two in mono. As a single unit I've seen reference to claims that it actually produces more like 90watt stereo @ 4, 8 & 16 ohm. For reference I'm driving a pair Vienna Accoustic Beethoven Concert Grand and I feel one is sufficient.
  13. Item: McIntosh MC275 valve power amp Location: Canberra ACT - I have the original box and I'm happy to courier at your expense and risk. Price: prices are FIRM $3400 with original McIntosh valves (200 hours) or $3750 with brand new Gold Lion KT88, JAN NoS Phillips 12at7 & 5751, with a Russian Millard in the v1. Item Condition: functions perfectly, cosmetically the unit has light marks on the stainless steel and some lettering is lightly worn. Please see photos. Reason for selling: Bought this to I could mono block but I want to go back to one and free up funds for other gear. Payment Method: Pickup - Cash, Paypal, COD Only Extra Info: The MC275 is a hifi icon in my mind, beautiful design and sound. I've found 75watts more than ample power for my Vienna Acoustics hence I'm looking at dropping back to one. Happy to demo if you are local or want to make the drive. Pictures:
