A-348 Performance Integrated Tube Amplifier (EL34/optional KT88) - reduced MSRP US$1100.00
Positive Feedback Online's Writers' Choice Awards - 2008
"The Grant Fidelity amp A-348, used in a huge living room with both the Michael Greens and the Windjammers, was a surprise. No sidewalls within "miles," the system I set up for my month long recovery from a knee replacement, presented a wonderfully believable soundstage with surprisingly deep bass and crystaline highs. The midrange was gorgeous, female voices were presented well. So well, I shook Ella Fitgerald's hand and thanked her for her performance. The idea of two chassis in one made (I hate to say this) solid state silence and those big tubes looked so cool! People who came to see how I was doing after the operation were shocked by the great sound, commenting on how "real" everything sounded..."

"It's such a big improvement"
- from customer Randy B. by email:
"...I want to let you know the A-348 is working wonderfully. It is such a big improvement I still cannot believe my ears. I thank you very much for helping me make this purchase. Also, the CDP is working and sounding great. The pair make a great system."
A-348 is an amazing AMP
I purchased the A-348 in late December 08. After using it for the last few weeks all I can say is wow. The amp is so open and accurate that I have upgraded my CD player to a mid-level Marantz with good quality DAC's and to new speakers. This amp reveals everything so if you use a cheap cd/dvd player - you will hear it. I am trying to keep the signal paths (input+output) as simple as possible, no preamp or tone controls. I thought I would miss those tone controls but I don't. What you hear is everything that was on the CD and it's mastering. I can now say that recording quality varies greatly from artist to artist - disc to disc. I have found the low end to vary the most - some discs are fine but on some it just seems they forgot to record anything below 50Hz. In the past, my powered sub would make up for that and artificailly inflate the bass. I don't miss that because now I hear the music - all of it as it was intended. I also like the fact that I can upgrade to 88 tubes and change the character of the amp and power output.
This is a purchase you will not regret and Ian and Rachel were great to deal with and answered any question I had.
Even my wife likes this amp
I'm running this amp right now. I am impressed greatly. It takes everything I throw at it and keeps going. Some say with the EL34s it gets muddled in the mids. Not with this amp. Even my wife likes this amp.

"This amp powered my Maggies with rock music..."
- by customer David C., Oct 2008:
Been using this amp, paired to a difficult to run Magnepan 2.5R, for about 1 year now. Beautiful combination! By far it's the best sounding amp I've ever owned, it's also by a long shot the least expensive of any of the amps I've owned. Previously I was running Bryston, Linn, and Audio Refinement (the multi-5 is a fantastic HT amp). I've never knew my Maggies was so bass capable until the A-348 came home with me. The top end was much better and the mid-range is smooth and delicious. A very musical and warm amp and is a perfect match for my CD only system. Was initially very concerned that this amp may be underpowered for my Maggies. Others have told me I need at least 150 wpc in order to properly run the Maggies. I need not worry. This amp powered my Maggies with rock music at a volume that annoyed the neighbours without much difficulty. Recently upgraded to the KT-88 and yes it was a huge improvement without spending a lot of $$. Highly recommend giving this amp a listen. Don't be surprise if you find you can't part with this amp. Take the money you save and spend it on music and beers. A lot of beers! PS - Dealing with Ian and Rachel at Grant Fedility is NOT like dealing with the big box stores or the "boutique audiophile" stores. Be prepared to get prompt responses and great customer service. If your used to dealing with the big box stores you've been warned. Might be in for a shock, at least you'll have a good stock of music and beers from the money you saved on the amp to help.
From a very happy customer, David Chen
"A-348 clearly gets me much closer to the music"
- by customer, Chris M.
Since I have not experienced many tube amps, it would be difficult for me to do an A/B comparison but the A-348 clearly gets me much closer to the music than my previous SS gear. For a very reasonable price, this amp added the fullness, soundstaging and level of realism that I suspected I was missing. I also played a number of CD’s through the amp and although it is not my preferred medium, it made them far more enjoyable, removing much of the hard edge I associate with CD’s.
