I think people get too hung up on efficiency of speakers. If your speakers sound great but don't get loud enough, scoot them closer to your chair. If you don't like the sound of them, that is much harder to fix. I bought a pair of Klispch Heresy II's based on people's reviews and I wound up really not liking them that much. Oddly, I thought they sounded the best with my 125 watt solid state Pioneer with a whole lot of feedback. I own an S5 K12, 2 Magnevox console amps (single ended 6bq5s and a push-pull 6v6) Tubelab SE that can be used with 300b 2A3 or 45 triodes. I have bought or borrowed about a dozen pairs of speakers in the last few years, and my favorates for these tiny amps are a pair on Von Sweikert VR2's and a pair of Dynaco A35s. Niether of these are every efficent, but I think they sound great. I have found that most of the time I need about 4 watts to achieve the listening volume I want (the 45s and 6bq5s can't quite cut it.) That is me though, some people like a lot more volume. And if I want to have a party or somthing I hook up one of my bigger amps. The bottom line is it does not matter how efficient speakers are, if you don't like the way they sound. I would reccomend listining to as many as you can.

That said, there are some high sensitivity speakers out there that are reasonably priced. I have no idea what you mean by budget, other than less than a Lascala. My favorate high sensitivity speaker I have heard has been the Sonist, I think they start at around $1800. I would really like to hear a pair of Zu speakers, I think they can be had for around $1000 for thier base model. Dang near everything Klipsh makes is at least in the high 90's. A pair of Heresy 1 or 2 can be found for somthing like $300 to $500. I didn't like them that much, but my friend really did, he pushed a much more expensive pair out of the way to listen to them, and it's been 2 years and they never left his house. There are a lot of newer tower speakers they make too that are in the high 90s. Newegg likes to put them on sale, I have not had a chance to hear any on a tube amp though. Lastly, nearly every large speaker Cerwin Vega ever made was at least 95db/watt. Some of these really don't sound good at all, but my friend has a pair of VS-120s that I think sound pretty nice on a single ended tube amp.

So anyway that is my 2 cents, take it or leave it. Speakers and amps that look like a great match on paper may not sound great in your living room.

As an element of a finished product, ok I see what you mean.

As a design decision / tradeoff .... I couldn't agree less. Sensitivity = super important.

Yea, I imagine I will get a lot of people disagree with me. I am clearly going against the grain here. I feel I should say it depends a lot on what you listen to, how big your room is, and how loud you want your music to be. 4 watts on 87-90 decibel speakers is loud enough for me most of the time. I'm sure that is not true for a lot of people. I will further conceed that extra headroom is never a bad thing, and operating amplifiers at or beyond thier limits can damage your equipment.

I recently purchased another MC10 (a T this time) at a good price, complete with very low mileage EH Tubes throughout. Part of the deal was the MS22-B phono amp but I was very disappointed with its performance. It really really is bad in being lacking of life and vitality, almost like its output was passing through a set of low pass filters. My home made SS versions just ripped it apart so I decided to rebuild it. I used the now defunct WAD (World Audio Design) circuit with some tweaks and wow! What a difference! OK so the WAD design may not be the worlds best but it now puts the SS to shame and for the first time in years I find myself preferring Vinyl to CD's. I never thought that would ever happen but this rebuild is nothing short of startling. At first I replaced the transistor buffer with a Mosfet to simulate the high impedance normally provided by a third buffer tube. Although this arrangement sounded so much better, going the whole hog with an extra 12AX7 tube really made this amplifier complete. The whole story is documented here for those who have the MS22-B and feel they are missing out with it too.

I need help!

I brought a Yaqin MS-2A3 integrated amp last year and it sounded great. Unfortunately, the right channel lost its power and not generates any sounds at all. Does anyone have the MS-2A3 schematic by any chance? Thanks in advance for your help!
