Monoblocks Fisher 30A or Mc MC30?
Any opinions?
Follow Ups:
Power difference not withstanding, these are 2 very different monoblocks.
The 30a has a lush "tubelike" sound- it really sounds like how people people describe tube amps as sounding. Midrange to die for, with surprising frequency extension, but bass only goes down so far.
The MC30 sounds like a cross between a SS and a tube amp. Tight bass and a quiet background like a SS amp; lush midrange and tube like imaging.
One of the best amp pair I ever heard was a fully rebuilt pr of MC30s. All new close tolerance parts, better power supply. NOS tubes. The best way to describe it would be natural. It neither added or subtracted anything and the soundstage and imageing were spectacular.
Best, Ross
Get a pair of Grommes or, Marantz 9s. Or, McIntosh MC3500s.

260, 250K, 221 or the earlier chrome models - 215BA, 216BA and 230BA are all nice. They're also more affordable than Marantz or Mac.
I preferred the Grommes 260 to the Mc amps save maybe the MC225. The Mc amps seemed too smeared compared to the Grommes and Marantz.

Got a pair which needs refurbishing badly. Most interesting design. I had Grommes which used two rectifier tubes, a 5U4 for power tubes and a 6X4 for input tubes: interesting. The 260 has 5u4 but interesting uses a 6L6 for a series regulator for the power tube b+. It also uses what looks to be an OD3 backwards to supply negative bias voltage. I may be wrong but I only took a cursory look inside....
Kinda cool
That's actually a 260A circuit with the 6l6 regulator. I've got quite a pile of the 260's including two 260As that are labelled 260, which may be what you have. I suspect he had the chasis made and then changed the amp but didn't bother ordering new chasis until he exhausted the chasis.
I just got one off of eBay with the original box like this and the box is printed 260 but had a hand written A following the 260 on the box. Either way, it's a good amp. The 250Ks are very similar but use 6CA7, and can sometimes be bought pretty cheaply on eBay.
I notice you love your Altecs. Interesting as they predate the ultralnear designs and used a fixed screen grid which I associate with better controlled dynamics. Also IIRC they used the Peerless 20-20 outputs, supposedly some of the best at the time.
but once Brian mentioned the Grommes, I do prefer the sound of my Grommes. I consider the Mac stuff pretty pedestrain, especially when you consider how much they cost. I've never owned the 225 but a friend of mine has a couple of them and he likes them a lot. I still have a 240, but that's mostly because I want to have some chrome Mac in the collection to go along with the earlier Mac that I decided long ago were keepers.
In addition to the Grommes, I would recommend the Scott mono amps as nice sounding alternatives, especially the 240 and 280. The 250 I consider a later step child. 232B's are also pretty good, but can be a little harder to find.
