Not necessairly - unless you buy into all the BS about esoteric components - by some of the more singel minded referred to as REAL HiFi.........
but - it's not cheap, either.... :roll: if you look carefully around teh DIYAuduo, you'll find quite a number of posters that refrain from all the mumbo jumbo, and still get very good results. A good tube amp won't necessearly cost very much more to build than some of the more hefty guitar amps presented here.
With guitar amps I'll think maybe if I throw some mouse turds, a desicated roach and some dirt from the vacuum cleaner in there I'll get it rght but with hifi I know I'll be temped by tantalum resistors, foil in oils, a drop in regulated heater board... Best stay away. Even with great self control it's impossible to resist quality iron, I know the GBP kills someone w/ dollars but even so check out the cost for a set of Williansons: ~$1800! :cry: I know I'd be fine with Edcors but I'll always be wondering what if I'd gone with the Sowters.

15 years ago I got myself a nice used Linn Sondek, Naim 250/102, Spendor SP1/2 system and stopped tinkering with hifi, store bought or homebrew, ever since.

few last notes to the OP, most of 'that sound' you want is in the speakers - the closest you'll get these days w/o too much invested are some 80s Rogers - LS2, LS6, LS7, Studio 1s. These are BBC school and designed flat rather than for bass and treble dazzle (ie mid-range suckout) like most contemporary stuff. They were still applying the philosophy of a large baffle and a carefully tuned resonant box. There's good new stuff around but it gets pricey if you want toneful accuracy and something other than mini monitors - of which I once read the sound described as the aural equivalent of looking through binoculars the wrong way.

If you wish to avoid DIY and tubes find an old Naim Nait 2 and Rogers LS2 mounted on 28" stands 10-12" from the rear wall. You'll have some rich sweetness without old bloat. Good luck.

Guys,
Many of you know that I came here from the HiFi design crowd. This power amp design (the Baby Huey) is the result of several years building and listening and has been built by 50 or more folk around the globe now.

The HiFi Amp I'm using now is a 6SL7 + PP 6V6 version of my Baby Huey design - baiscally the design on posts #1261 and #1262.

The 12AX7 PP EL84 version is also lovely and is at posts #602 and #603 here.

There is also a "basic" version which has its own wiki, see here:

If you have an ST35 as a donor amp may I recommend my design. Also easy enough to build from scratch.

It can also be built using two ECL86 (6GW8) Triode/Pentodes.

Cheers,
Ian

Well it is the Fourth Edition of the RDH, which came out in 1952. This one was printed in USA in 1960 by RCA. I bought it from an on-line used book dealer, with condition listed as good, with owner's name inside. When it arrived I was pretty shocked to find that name, and from what I can tell it is the signature of the McIntosh Labs founder.
