Another data-point on the 901s and power: As previously written, the 1.25s and 901s ae both connected to the same AQ niagra 5000, which is connected through a hubble outlet to a dedicated 20 amp circuit supplied by an equitech balnced power system.
With the D1100 upgrade I am able to sit in the room and enjoy really loud dynamic music (just not for too long or too often out of respect for my hearing). I engaged the 901s protection system (the 1.25 still had headroom) and I'm not sure if it was tube section or SS section or both, as both needles were bouncing off the edge of the meter, without ever overloading the Niagra or the circuit.

I see you have extensive experience with mac. I have also built a cave system with two 1,25 and 901 not yet set up. Cant wait to hear those babies. Have you had classe m600s before and what is your pros and cons vs the mac gear? Im also a classe delta mono fan and found good synergy driving bowers 800d1 and 802d3s. The mac gear is going to be hooked up to bowers matrix 800(the pointy Ones from 90s).

I have the xrt2k running with 1.25 on bass mc901 (solid on mids,valves on tweeters). Im thinking of bridging mc901 (used on mids) and being able to get balance right with 901s crossovers. ThEn investing in either in mc601 or 611s for tweeters. One forum member mentioned he had 2 x 2kw hooked up to xrt2k! What are your thoughts?

Mcintosh Mc 901 vs Mc 1,25
I like to ask you , i have the b&w 800 d3 , but i don't know what to buy
the Mc 901 vs the Mc 1,25 kWh what do you think what i must take? i know from a store in Canada , he told the Mc 901 is the best for the sound and if you like more power take the 1, 25 kWh a shop in my country the Nederlands ,he told take the new Delta series form Classe ,in a review the Classe was bit better than the Mc ,1,25 kWh. but the people next door ,don't like a play hard. Thanks |

I would love to try the 901 but my V1 Focal Scalas are not biwirable. I have heard to 1.25 and it sounds great but I prefer the tonal balance of my 275’s or 2301’s. No doubt there is deeper tighter bass with the SS design. The hybrid tube/SS output of the 901 seems perfect. Another thing to consider is while you can run the KW1.25 with only one speaker cable run, the MC901 requires two dedicated lines per channel. If you like your cables exotic the cost of a second run is not inconsequential. Whether one $5,000 run is better then two $2,500 runs is a whole different kettle of fish. Mike S. |
