Moscode 402au vs Butler TDB2250 vs McIntosh MC275


I am using a McIntosh MC275 with an Aesthetix Calypso preamplifier and Sehring 703 speakers (86dB at 8 ohms). The Mac has great mid-range timbre, detail, and high end extension, but the bass and soundstage width could be better. I primarily am a fan of rock music, but find I mainly listen to more laid back music (Norah Jones, Feist) with the Mac because hard rock doesn't sound all that convincing. So I am looking to buy either the Moscode 402au or the Butler TDB2250 to replace the Mac, having read good comments about both hybrids, hoping for better bass and soundstage without sacrificing too much mid-range warmth.

OK, long preamble over...has anyone compared the MC275 to the Moscode or Butler? Any thoughts or advice?

Pdreher, thanks for your comments. Can I ask what integrated you are using now?

In any case, you may well be right, as the Mac does sound great in most respects. If I ever move into a bigger space, I could then buy a second MC275.

In the short run, one option is to buy a good used solid state amp that is fairly inexpensive and hear if the Mac can really be improved upon with a more powerful amp. I also could take Moscode up on the offer of a 33 day free trial and see if it is really better...
Mcondon - The first integrated I tried after separates was a Musical Fidelity Nuvista M3... a big disappointment. I knew instantly that it was all bling, with little substance... I listed it within 3 days of getting it. Even ended up paying the next owner to get it's caps replaced, even though the guy I had bought it from had just had similar repairs done 6 months prior.

Next, I went back to McIntosh and used the MA2275 tube integrated for about 3 months. The MA2275 is a very nice integrated. I really liked it... excellent build quality and very good sound. It just did not provide enough drive for my big Harbeth's and did not have the transparency or soundstage that I had grown accustomed to with my previous favorite separates setup (MC275 MKV & Aesthetix Calypso). I doubt I will ever down-grade again unless it's out of financial necessity.
A friend had a Moscode 401 and upgraded to a 275 and was very happy. Like you he thought the 275 had a weaker bass. He also bought a second 275 so he could run them mono.

Well, I switched to speaker cables from Clear Day Cables and placed the MC275 on a Mapleshade amp platform. Those changes, which were fairly inexpensive, have significantly improved the bass and dynamics of my system. So for now I am happy with the Mac and Aesthetix. They really are transporting with well recorded music.

The Moscode still appeals to me, mostly because the extra watts would help with my relatively inefficient speakers. But for now, the Mac is fine...
