View Full Version : Slightly OT: Small Amplifier recommendations

Folks:

I am about to install an SB2 in a room on a shelf with shelf speakers
(Mission M30is -
http://www.mission.co.uk/product/m3iseries/loudspeaker_m30i.htm ).

My problem is the shelf is 25cm (10in) deep and I need a reasonable
amplifier to sit between the SB2 and the speakers that fits on the
shelf. This sounds like it should be easy, but it's not been very easy
so far. Most hifi separate amps are 30cm deep at a minimum.

The only amp so far I've found has been the Creek A50i which is 23cm
deep (just fitting with an RCA at the back) but it's a bit over the top
for the room and pricey at GBP 479 (USD 800+).

I've been through the archives to the list and seen some of the in-wall
suggestions, but I don't really have that option as I've just
replastered :)

I recall seeing an amp that was designed for PC amplification alongside
a laptop as part of following a thread on this list once, but i can't
find it at all.

Anyway, what I need is:

- a decent amp (by decent i mean it has to deliver a sound I'm likely
to enjoy - I've been quite impressed by Cambridge Audio's A1 & Azur
range so that is the kind of thing I'm after.
- nothing too expensive as it's only driving bookshelf speakers (that
are pretty good for their size)
- 23cm or less deep and not wider than a standard piece of hifi
separate (I could use something like a second hand NAIT 1 put sideways,
but there's no guarantee of getting them at a reasonable price)
- available in the UK

Anyone any thoughts or suggestions they'd care to share with me ?

Thanks in advance

...Iain

Cheap and apparently good: http://www.si-5.com/frontEnd/cm_productDetail.jsp?productID=18. Reviewed here: http://www.tnt-audio.com/ampli/t-amp_e.html. Just set the volume at a fixed position, and use the SB for volume control.

Has anybody got a recommendation for small speakers to go with this?
I don't recall seeing one on the list.

I'm aiming at a system with SB2 that is easy to move from room to
room. I'm in England, by the way.

I used Edirol (part of Roland group) active monitors that have the additional advantage of digital input as well as excellent sound for the price...
http://www.edirol.com/products/info/ma10dbk.html This is the set I use but they have larger and smaller units as well. Obviously not as high end as some monitors but don't have the price tag either.

Look a bit weighty to me. My hi-fi dealer has suggested (I indicated
that this was not even my secondary system, but tertiary) the Tivoli
Audio Model 2, which is actually a stereo radio, genuine stereo as it
has a second speaker. Supposed to be good, but I don't really need
the radio part.

Also, though active speakers are a possibility, I was specifically
thinking of ordinary speakers with that interesting-looking small
amplifier.

For a terrific small amplifier, you might look into the SE9 single-ended tube amp from Norh. I have one in my office with some high-efficiency speakers from Omega, and it sounds better than anything else I've ever owned. As long as you have relatively efficient speakers the SE9 can put out plenty of volume for most applications. Their website is http://www.norh.com.



And, it is certainly interesting looking, esp when the tubes get glowing.

Hrmmm... $450 for a 9 watt per channel tube amp, or $20 for the Sonic Technologies T-Amp that many reviewers have raved is a sonic marvel besting $1000 amplifiers that serve similar purposes.

Hrmm.....

Are there any UK suppliers for the T-amp? Also, could I repeat the request for recommendations of small speakers that would be well paired with the T-amp? Ideally, they would cost 15 pounds and be better than 1000 pound models... ;-)

Max

PS Has anyone noticed the price for the ac adaptor on the t-amp pages? It's 1/2 the price of the amp!

I'm using one of the T-Amps in the kitchen now and it's been
terrific. Not critical listening (you can't hear much above the
screaming), but impressive for the cost...

I've recently built an AMP3 kit from www.41hz.com. This is based on a tripath chip similar to the T-amp. I powered it from a 15 13.8v psu from Maplin (in UK). I've been comparing it with my (old and mid-fi) Linn Intek amp and I'm much impressed (more transparent, tighter, faster). I'm now planning to use the AMP3 boards to drive my planned SB based multiroom installation.

Sounds great. Do you need a preamp, or will it just connect straight to the Squeezebox?

Stuart,

The line level outputs from an SB are sufficient to drive an AMP3 happily. The AMP3 has a single stereo input, so if you want to change sources without unplugging then a passive selector or preamp will be required.

If you use volume control on the SB then all you need is the AMP3, PSU and some speakers. If you are feeding the AMP3 from a DAC and have the SB set to max (for best quality) then you will need some form of volume control before the AMP3, you can easily wire in a quality stereo potentiometer to do this.

The basic AMP3 gain is either set by the input resistors and is fixed when you build it. I am using the AMP3 with an SB1 at the moment and I think the default gain setting for the AMP3 I set at build is maybe a bit too high (certainly for internet radio, but not for classical cds ripped to FLAC). I hope to receive my SB2 this week and will test this as well to select the gain before I build my next AMP3.

Total cost - AMP3 23 inc postage, PSU 15 (could be upgraded), Basic Case & HW - say 15, about 6 hours effort for first assembly (will get lots faster), and very tired hands from winding toroids. I think this is brilliant deal for the quality, but the little TEACs do look much prettier and save fiddling.

Thanks Chris, I think I will invest in one. I have an old Pioneer A400 amp, thats far too big for my bedside table, and probably consumes a fair bit of power too. I only use it for an hour at night, and the volume is low.

Another idea, if no-one has mentioned it yet, is to use
these (http://www.edirol.it/europe/details.asp?code=362&id=12&la=UK) monitor loudspeakers which have a digital in socket. Don't know what they sound like though, but it's an extra option to think about.

I have a pair of the similar MA-20D's -- they sound excellent.

and as a possible midpoint in fiddliness between the Teacs and the AMP3,
you could purchase a Sonic Impact T-Amp and repackage the works with
decent connectors and a power supply. probably still only about a
$60USD investment (and no torroid winding) would net you a pretty nice
sounding little amp.

options.

here's another line of teac that i've been happy with and the units are not that expensive
