WHEN I LOOK AROUND MY LISTENING ROOM AND SEE ALL THE WONDERFUL EQUIPMENT THAT I PURCHASED FROM MONARCHY AUDIO; THE "DIP CLASSIC, THE TWO "SM-70 PRO ZERO FEEDBACK POWER AMPS, THE TWO DAC AND LINE AMPS, THE MIND BLOWING 300B TUBE PRE-AMP AND OF COURSE MY MOST PRIZED POSSESSION; THE SE-250 HYBRID MONO-BLOCK AMPS. MY LIFE CHANGED THE DAY I DISCOVERED THE MONARCHY WEBSITE. FINALLY I COULD REALIZE MY DREAMS OF HAVING TRUE AUDIOPHILE EQUIPMENT. IF THAT WERE NOT ENOUGH, THE FACT THAT ANYTIME I HAD ANY QUESTIONS, I CALLED AND WAS GRACIOUSLY INDULGED BY THE VERY SAME (IF I MAY, GENIUS) THAT CREATED THESE WONDERFUL AUDIO PRODUCTS. PLEASE FORGIVE MY EXUBERANCE BUT I LOVE MY MONARCY AUDIO EQUIPMENT AND I LOOK FORWARD TO WHAT NEW PRODUCTS YOU MAY OFFER IN THE NEAR FUTURE. THANKS SO MUCH

Received the monos in perfect condition. They are wonderful. I left some positive feedback for you on Audiogon. Please do the same for me. Username is EHoehn. I will be positing a review on audiocircle in the coming weeks. I will send you a copy

I gather you will pay somewhere between US90 - US250 for a good NOS pair. I am about to put them up against some 1950`s Tele ECC801S AT7 or 802S AU7 tubes from a reliable source. I will let you know the outcome. Bare in mind I am not using any other tubes in my system yet as I have not received my NM24 from Lenehan audio. It is still getting modified along with my Marantz CD80 transport. I can`t wait. Mike says I will be floored.
Two things - people keep telling me that a good 12AU7 should usually sound better to some extent than a good 12AT7(so far the only evidence I`ve heard is the cheaper Mazda beating the highly regarded expensive GEC A2900). If that is so then I might be inclined to try the early tele 802S instead of the 801S when I compare with my Mazda silver plate.
ATM I am clipping my Yamaha preamp if I turn volume up to far. BUT before this happens the sound is very very nice indeed. My current cdp is of pretty good quality and I am using GE NOS cable as dedicated lines and good quality cables. I will be purchasing a regenerator from you soon and some sort of power isolation.
You might be interested in knowing that I am a huge believer in cables and had quite a few on hand for the 250`s. I tried many big buck PC`s on them. Quick exampe - Virtual dynamics Master (nice but a bit unnatural sounding), Lessloss DFPC(too uninvolving a bit bland),NOS GE cable(quiet nice smooth balanced dynamic),Purist Dominus(similar to NOS GE but less resolution and dynamics) BUT when I plugged in the huge Z-cable Cyclone Ref1 cables .... VOILA! Your 250`s love these cables. So smoooth and quiet yet everything is there/happening and very musical. I love this combo especially with the Mazda tubes! To compliment this I finally decided on the Audioquest Anaconda with Eichmann plugs. These ic`s truly sound nice on your 250`s. Nice extended very airy top end with good detail and everything else is very good. I went through many ic`s before settling with the Anacondas. Only other cables that sounded similar with slightly better resolution soundstage midrange on your 250`s was Z-cable(now clarity cable) current model Organic cable. I sent this cable back as it was too expensive to buy and my Anaconda sounds good enough. I will try the Organic again after I receive the NM24. I tried about 10 - 15 of my favourite highly regarded ic cables on 250`s including your DR-2 which sounded good well balanced for the price but a good ear will pick up improvements using other higher priced cables especially in the top end with the 250`s.
I have not played with many speaker cables as yet but my nice reference GE NOS cables seem to let everything through clearly and smoothly as always. Sorry to ramble on but I must say the above combo of cables on your 250`s sure sound sweet to my ears and everyone else that has listened. I am very happy! I had serious doubts that your amps could compete with my previous highly regarded and very popular current model Spectron musician III amp with all updates. What a great amp. With average cables and tubes Spectron beats 250`s in every area. BUT your amps really do seem to respond allot to great tubes and cables. With 250`s setup as described above I really do think I`m enjoying them more than Spectron even with good cables on it. Of course Spectron beats 250`s with more headroom etc at 600wpc and has better extended bottom end but heck listening to the 250`s atm I am not really missing that extra power at all as they are sounding great.
Plus I use a quality Revel B15 sub which is very tight fast and musical. Anyway my Lenehan ML1+ speakers are imaging like champs and sound big and beautiful.
Well done once again for a great design with loads of potential at an affordable price! SE-250`s are winners in my book!
I want you to clarify one thing for me again if you don`t mind.
Are you sure that I will have all the gain necessary with the NM24 to drive the 250`s using AU7ubes??? Please advise again. I want to be sure because I have not played with the NM24 yet and will not be receiving it until April sometime. This information will help me decide which Tele tubes to try next as described at beginning of mail. If you are sure that NM24 will fix slight gain issue I am experiencing atm with AU7 tubes then I will stick with this tube type instead of AT7.

When we hooked up the SE-250's I immediatley noticed the great midrange and highs we were looking for. Detailed with a liquid feel that was missing from our previous solid state amp. The bass seemed a little thin, but I thought this was probably because my VMPS RM-2 speakers were over damped. This turned out to be the case. After I adjusted the putty on the RM-2 passive radiators, the bass was back and the music had a lifelike full feeling. I'm pretty poor at discriping how a piece of equipment sounds. Like alot of audio buffs, we have reference songs to test aspects of a a new piece of equipment.
One song for bass response,one for female vocals, ect. I started to go through this list but became too involved with the music to continue. Instead I started going through our CD's wondering how The Monkees and other "nonaudiophile" selections would sound. I think the ability to make one listen closer and more to music is the best compliment one can give. The SE-250's do that.
Thanks Kim Schroeder
I read the article from "Secrets of HomeTheater and High Fidelity", and itâ€™s too late the word is gettingout. One of the things that persuaded me to go with the SE-250 over theSE-160 is the beautiful faceplate you designed; all my audiophile friendsand my wife love them. Even my teenagers thought they were â€œkoolâ€?. If you could do it this would be a great upgrade option for your wholeline. I wish more manufacturers would make attractive faceplates as Iconsider my equipment a large part of my home decor (since it fills alarge part of the room) and therefore it must be pleasant to look at aswell.
Attached is a picture of my living room with all the equipment togive you an idea of what I mean. If you look closely at the pictures Imade some brass cylinders of various heights and widths to put under andon top of your amps, my speakers and other equipment. My friends and Iseem to really enjoy the sonic upgrade they made for only a small outletof cash. You can borrow some if you would like to try them. Your DIP andUpsampler are still in my home theater room and doing fine. I will becoming by soon for some more DR-1 interconnects, as they are quiteaddictive. Lastly the audio cables you sold me a few days ago are amazingfor only $49 and sound better then the $500 cables they replaced. Youwere right; you can get true hi-end sound without spending a fortune.
Nowif you would only design a new pre-ampï¿•••ï¿•••ï¿•••I might be reae ready foranother change. I seem to be becoming quite a fan of Monarchy equipment.
The Dynastats are themselves a joy. I am quite mindful of thecircumstances of their sale and can only express my gratitude.
I hope that your weekend was an enjoyable one.
When I got your email I thought that I would try putting in the Phillips 6922's intothe M24's output stage as suggested. Interestingly enough, I did not like theresult. For whatever reason, I felt the highs were very harsh - excessivelyso. I then replaced the 6922's with the stock tubes of the M24 and I think thatI've got the best sound coming from my discs that I can get; save spendingthousands of dollars more, which I won't be doing. I just want to say theresults of using your electronics is nothing short of amazing and given theprice point, almost too good to be true.
I have the M24 DAC connected in between my transport, which is nothing special; a Pioneer Elite unit, and mypre-amp which is another Pioneer Elite product, model C90, which is, I think, a great solid-state preamp. I use the Monarchy upsampler, and set the samplingrate at 96 kHz. As interconnects, I use Monarchy digital cables (1/2" model)between the transport, upsampler and DAC.
